Abstract

Tillandsia L. genus comprises 649 species, with different uses at different times. T. usneoides L. uses are reported since the late-archaic and pre-Columbian cultures. In XIX-XX centuries, T. usneoides was used in some manufactured products, as polish and packing fruit. Tillandsia has a favorable reputation as medicine: for leucorrhea, rheumatism, ulcers, hemorrhoid treatment, as an anti-diabetic remedy, emetic, analgesic, purgative, contraceptive, antispasmodic and diuretic. Tillandsia chemical composition includes cycloartane triterpenes and hydroxy-flavonoids, which are present in at least 24 species. Several extracts and compounds from Tillandsia spp. have been reported with pharmacological actions, as anti-neoplasia, hypolipidemic, antifungal, anti-HSV-1, hypoglycemic and microbicide. This review communicates the economic importance, ethnobotany, chemistry composition and biological activities of the Tillandsia genus, and analyze its biological and economic perspective. Tillandsia genus has cultural, economic and pharmacological relevance, with a high potential in many essential aspects of the modern society.

INTRODUCTION
Bromeliaceae family includes 57 genera and 3,350
species (Luther, 2006). They are distributed
predominantly in the Neotropical region, from
southern Mexico through Chile and reaching the
North-American Southeast (Manetti et al., 2009).
Except for Pitcairnia feliciana (A. Chev.) Harms &
Mildbraed, Bromeliaceae is considered an endemic
family of the Americas (Givnish et al., 2007) that
comprises eight subfamilies: Pitcairnioideae,
Tillandsioideae, Bromelioideae, Puyoideae,
Navioideae, Hechtioideae, Lindmanioideae, and
Brocchinioideae. They differ for: growth habit,
trichrome, type of fruit, seed, leaflet, photosynthesis,
and pollinator; as well as its epiphytes, growth, and the
chlorenchyma (Crayn et al., 2004; Givnish et al.,
2007; Vasconcelos et al., 2013; Givnish et al., 2014).
Tillandsia genus has over 649 species and
includes members with distinctive morphological and
physiological characteristics (Pickens et al., 2006;
Gouda et al., 2016; Granados et al., 2016). Most of the
species of the genus are epiphytes of trees or live on
rocky slopes, preferring to settle in Quercus spp. tree
branches, because of its rough bark. They possess
leaves covered with peltate trichomes and are arranged
in rosettes; whereas the inflorescences are bracteates
with bright colors (Diego-Escobar et al., 2013). All
Tillandsia species are epiphytes, living independently
of the soil, on trees or inert substrates, such as electric
power-line wires (Brighigna et al., 1997). In these
species, the lack of an absorbing root system is
substituted by a specialized structure named trichrome
that is essential for water uptake and other nutrients
(Papini et al., 2011). It is known that around 27.614
species are vascular epiphytes, with 913 genera in 73
families (Zots, 2013), representing approximately 13%
of the species of vascular plants (Kress, 1986; Douglas
et al., 1987).
Tillandsia genus is the most primitive and
xerophyte of all Bromeliaceae family (Garth, 1964).
Carl Linnaeus called to the genus ‘Tillandsia’ in honor
of his Finnish teacher Elias Tillands (Vasconcelos et
al., 2013). From the beginning of the formal
investigation of the Tillandsia genus, it has awakened
much interest. Authors like Dubois (1917) mentioned
the extreme adaptability of T. usneoides in their host
as ‘carnivorous plant.' Also, Billings (1904) reported
the great versatility of T. usneoides, which during the
dry spell in the spring of 1902, was exposed to a
period during without rain during two months without
suffer injury. Nowadays, Tillandsia species has been
reported with qualities for pollutants environmental
monitoring (Capannesi et al., 1987; Figueiredo et al.,
2004; Elias et al., 2006; Cardoso-Gustavson et al.,
2016).
Although, Tillandsia genus species possesses
cultural relevance, economic importance, and unique
ecological features, also is used in traditional
medicine, with repercussions in the treatment of
human illness. In the present review, we report the
historical uses, customs, chemistry, economic
importance as well as biological activities of
Tillandsia genus species, empathizing the most
relevant since the point of view ethnomedicinal and
analyzing its biological and economic perspective.
Culture importance, uses, and customs in the
Americas
There are different applications of the Tillandsia
species reported in the Americas. Two of the plants
more reported are T. usneoides and T. recurvata,
commonly called ‘Spanish moss' and ‘Ball moss,'
respectively. The first hint of the use of Tillandsia
happened by T. usneoides fibers, which were found in
the pottery-making societies of North America before
our era (Smith & Trinkley, 2006; Gilmore, 2015). The
interest in Tillandsia plants was confirmed in the 19th
and 20th centuries.
One of the first uses of T. usneoides was
proposed throughout a patent for treatment and cure of
the decomposition of the bark of the trees (Cummings,
1880). In the early 20th century in Louisiana, Florida
USA, T. usneoides was used in the winter by farmers
when the pastures were scarce, whose often chop
downed trees and allow the cattle to feed on the moss
(Halligan, 1909). T. recurvata was used with the same
purpose in Brazil (Vasconcelos et al., 2013). In this
same century, T. usneoides was suggested as a product
very versatile in USA (Schorger, 1927), as for tanning
hides (Hall & Tuttle, 1918), and as a possible source
for a hard-natural wax and for processing of
upholstering fibers (Feurt & Fox, 1953a; Feurt & Fox,
1955). Besides, the waste material from the processing
of threads for the upholstery industry was suggested as
a source of estrogens for cattle, to improve meat
quality and the efficiency of feed utilization (Feurt &
Fox, 1953b). T. usneoides was also used to eliminate
the bitter taste of citrus for use in animal feed
(Sokoloff & Redd, 1951).
Interestingly, the cultural importance of the
Tillandsia plants is prominently most wide in the
different Latin America countries that in other parts of
Estrella-Parra et al.
Chemistry and biological activity of the Tillandsia L. genus
Boletin Latinoamericano y del Caribe de Plantas Medicinales y Aromáticas/241
the Americas. Avila (2012) reports that Tillandsia spp.
was probably known as ‘chicōm-ācatl in pre-
Columbian cultures, which was used in Aztec temples
as decoration (Pierce, 2000). Other Tillandsia species,
like T. purpurea Ruiz and Pav. are depicted on pre-
Incan Mochica pottery of northern Peru, often within a
magical context (Arslanian et al., 1986). Also, in Peru,
T. usneoides was used to wrapping fruit and fragile
objects, as well as filling pillows and mattresses
(Pierce, 2000).
Tillandsia species can propagate and live in
trees of economic importance as cacao and shrubs as
well as in power-line poles. Due to that Tillandsia
species grow in other plants with more significant
commercial o social value, they were considered
parasitic plants (Rodriguez, 1955), and some
herbicides against T. recurvata and T. usneoides were
proposed (Rodriguez, 1955; Cole, 1959; Cardenas,
1971; Johnson & Halliwell, 1973). Fortunately, this
practice has disappeared in some regions thanks to a
better knowledge of the cultural, ecological and
economic importance of the Tillandsia genus.
Ethnobotany
While in the USA the plants of Tillandsia genus were
used practically in everyday needs, in Latin America
the past knowledge of this genus affected on the
culture of these countries, particularly in its traditional
medicine. For instance, in Peru were reported several
Tillandsia spp. with magical connotations, and some
species are used in rituals as adornment, especially: T.
usneoides (salvagina), T. walterivar (Sara-Sara), T.
cauligera (huiccontoi) and T. walteri (pasto verde)
(Arslanian et al., 1986).
In México, T. usneoides had an essential use
in Azteca society and posteriorly in post-Colombian
time like decoration in scenes of nativity in Chiapas
(Gardner, 1982), as well as T. religiosa in Morelos
(Hernández-Cardenas et al., 2014). In Tarahumara
community, T. mooreana L.B.Sm., usually named
‘waráruwi’ together with the ‘peyote’ (Lophophora
williamsii), are important plants used in its rituals
(Bye, 1979). Recently, the Otomi community of San
Bartolo Tutoltepec, Puebla, use this resource as part of
their wardrobe flying in the Danza de Los viejos,' this
to show himself as one of the old of vegetation, in an
ancient dance in the community (Stresser-Peann,
2011). Today, these plants can purchase in markets
mainly for ornamental purposes (Monteiro et al.,
2011).
Economic importance
The Bromeliaceae family is of horticultural interest,
mostly due to their growth forms and brightly colorful
inflorescences (Vervaeke et al., 2004). Today, from
Belgium and Holland millions of Bromeliaceae
seedlings and tens of thousands of finished plants are
imported into the USA (Cathcart, 1995). Only in
Florida, the commercial crop of Bromeliaceae has
been estimated at $20 million per year (Cathcart,
1995). However, some Tillandsia plants are
endangered (CITES) (Bessler, 1997) and it has been
sought techniques for its improvement and care. In
Brazil has been improved the conditions of growth
Tillandsia in the greenhouses due to the presence of
the mosquito Aedes aegypti, which is vectorized by
crows (Soares, 2005).
The plants of Tillandsia genus have received
hormonal treatment with 6-benzylaminopurine (6-BA)
as well as gibberellic acid, to accelerate the
multiplication and propagation velocity of the growth
(Chekanova, 1980; Bessler, 1997; Ding et al., 2009;
Ding et al., 2014). Also, it has been developed a
medium of culture to accelerate the propagation of the
plant (Zheng et al., 2013), including a specific method
with a particular medium of culture for Tillandsia, as
well as many fertilizers suitable for its growth
(Wrinkle, 1973; Sanchez, 2007; Ding et al., 2013;
Wang et al., 2013; Wang et al., 2014; Zheng et al.,
2015a; Zheng et al., 2015b; Wang, 2015; Zheng &
Ding, 2015; Ding et al., 2015a; Li and Zheng, 2015;
Zhang, 2016).
T. cyanea Linden ex K. Koch is used as
organic fertilizer in many Asiatic countries (Zhang,
2016). Also, T. usneoides is used as a decorative
arrangement in buildings (Wickham, 2013), as
ornamental plants in vertical type support, as air
purification indoors (Kim, 2011a; Kim, 2011b) as well
as green plant curtain (Yu et al., 2009). Interestingly, a
portable container accessory for clothing
transportation of Tillandsia plants has developed
(Sadaki, 2006). Also, with plants of Tillandsia have
been made ‘live pictures’ and jewelry for women
(Blió, 2013).
The speciation also has been of commercial
interest for the genus, and it has been developed
hybrids to commercialize them (Skotak, 2016), and
new cultivars of Tillandsia ornamental plants with
economic importance developed. Some varieties
known are: ‘Mora’ of T. leiboldiana Schltdl. (Bak &
Steur, 2011), ‘Jose’ from T. cyanea (Van der Velden,
2009) and ‘Tilstsil’ from T. stricta Sol. Ex Sims

(Osada, 2004). This activity satisfied the use of
technology for promoting the growth of the plants
(Ding et al., 2015b; Zheng et al., 2015b), which
reflexing the interest for improving and developing
crop in this genus.
Tillandsia genus possesses importance also in
the cosmetic industry. Aerial part extracts of T.
usneoides, T. cyanea, T. tectorum, T. ionantha, and T.
stricta improve rough skin and keeping moisture
(Ohara & Hori, 2001; Shoji et al., 2003; Kurokawa et
al., 2004; Yokozeki, 2010). Moreover, from T.
usneoides has been developed an anti-aging cosmetic,
which promotes the keratinocyte differentiation in the
skin (Kwon et al., 2013; Jung et al., 2015). All this
denote the commercial interest associated with
Tillandsia plants, whose potential real in this area
should be explored in further studies.
Medical traditional use of Tillandsia
In traditional medicine people mainly recommends the
use of aerial parts (leaves and stems), only leaves or
the complete plant to prepare remedies for many
ailments. Also, it has been reported the use of
inflorescences and roots, including preparations from
fresh plants. In South Louisiana, USA, people use the
decoction of T. usneoides in diabetes mellitus control
(Keller et al., 1981) and for hemorrhoid treatment
(Agra et al., 2008). In Latin America, T. recurvata is
usual for leucorrhea (Adonizio et al., 2006),
rheumatism, ulcers, hemorrhoids, eye infections,
gallbladder, and as antispasmodic agent (Paz et al.,
1995; Agra et al., 2007; Agra et al., 2008;
Vasconcelos et al., 2013). T. recurvata is used in
Bolivia for kidney inflammation (Bourdy et al., 2004).
Meanwhile, T. streptocarpa Baker as purgative and
laxative (Agra et al., 2008), emetic, analgesic and anti-
inflammatory remedy in Brazil (Delaporte et al.,
2004), as well as contraceptive agent (Delaporte et al.,
2006). T. loliacea Mart. ex. Schult. f. is used in the
treatment of external ulcers (Agra et al., 2008), as an
anti-rheumatic, and for obstructed liver (Braga, 1976).
Additionally, T. stricta is used in the vicinity of the
Parana River as a diuretic, in gonorrhea treatment and
as an anti-inflammatory (Lucietto et al., 2006).
In Mexican traditional medicine, there are
more than 30 Tillandsia plants reported (Table No. 1),
being the most critical T. recurvata and T. usneoides,
which are used for cough, bronchitis, rheumatism,
ulcers, and hemorrhoids, among other (Bennett, 2000;
Acebey et al., 2006; Grijalva, 2006; De Fátima et al.,
2008; Zamora, 2009; Hornung-Leoni, 2011;
Mondragón et al., 2011). Moreover, in the traditional
medicine of Amatlan, Veracruz, T. recurvata is used
for menstruation concerns (Smith & Downs, 1977;
Smith-Oka, 2007; Smith-Oka, 2008). Also, the leaves
of T. imperialis E. Morren ex Mez are used for
digestive disorders, respiratory tract, hemorrhoids,
inflammation and burns (Sandoval-Bucio et al., 2004;
Vite-Posadas et al., 2011). However, in most cases,
little attention has been placed on the experimental
validation of their medicinal properties.

Chemistry
In general, the compounds from the plants of the
Tillandsia genus have been isolated from organic
extracts, mainly alcoholic (methanol and ethanol),
although also acetone, chloroform, hexane, and
benzene were used. Some extracts have been explored
by CO2 supercritical fluid, and minor attention has
been put in the more polar compounds in aqueous
extracts; hemisynthesis has also been practiced for
some reported compounds the genus (Table No. 2).
The primary compounds in Tillandsia genus are
triterpenoids and sterols (51%), flavonoids (45%) and
cinnamic acids (4%) (Clemes et al., 2008;
Vasconcelos et al., 2013). Historically, in 1861 ash
content for T. usneoides resulted in chemical
properties (Schorger, 1927). However, the
investigation about the chemical of the Tillandsia
genus was initiated at the beginning of the XX century
by American society. Thus, T. usneoides was initially
reported containing as main constituents, water
(15.95%) and carbohydrates (69.50%) (Halligan,
1909; Schorger, 1927; Seldon & Feurt, 1953),
cellulose, (Wise & Meer, 1936), proteins (Pickell,
1890; Halligan, 1909), and wax, which represented a
possible commercial source for natural wax (Schorger,
1927; Seldon & Feurt, 1953).
The first chemical analyses of ash of Spanish-
moss T. usneoides were reported containing Na2O,
K2O, MgO, CaO, Fe2O3, SiO2, P2O5 and SO3
(Halligan, 1909; Wherry & Buchanan, 1926; Wherry
& Capen, 1928). T. usneoides was reported containing
sugars and other non-identified chemical constituents
with potential commercial value (Marsden, 1918) and
a sample of this species, which was recollected in the
winter season, it was reported with 15 mg/g and 46
mg/g of carotene and ascorbic acid, respectively,
representing nutritional levels of interest for cattle
(French & Abott, 1948). T. aeranthos (Loisel) L.B.
Sm. was reported containing polysaccharides (Moyna
& Tubío, 1977).
Although the value mineral, bromatological
and nutrimental of T. usneoides was already known, its
first secondary metabolite, a phenol methyl ether
glucoside, was described for Schorger in 1927, who
also reported chlorophyll and a sterol (Schorger,
1927). The corolla of T. fragrans André (Salgues,
1955) contained 0.18% of essential oil and 74% of
several free alcohols as citronellol (52%), geraniol
(20%), and nerol (2%), as well as 18% of esters. These
findings allow hypothesizing about the possible
obtaining from T. fragrans of a fragrance of cosmetic
interest, which also should be explored in other
Tillandsia plants.
Until the 60s and 70s, the chemistry of
Tillandsia was more addressed toward its biological
activities, probably due to the development of tools
and techniques for the identification assertive of
molecules.
Table No. 2 enlists the chemical compounds in
distinct Tillandsia species. McCrindle and Djerassi
(1961) and Djerassi and McCrindle (1962) reported 15
cycloartanes triterpenoids isolated of T. usneoides
(compounds 1-15). Ten years later, Atalla and
Nicholas (1971) reported similar compounds, sharing
at least three compounds 19, 20, and 21). Later, Lewis
and Mabry (1977) reported the first poly-hydroxylated
molecule: 3,6,3’,5’-tetramethoxy-5,7,4’-trihydroxyfla-
vone, corresponding to a compound iso-flavonoid type
(Table 2).
From the decade of the 90s, the growing
interest for the Tillandsia plants in the scientific
society increased the number of reports. Cabrera et al.
(1995, 1996), Cabrera & Seldes (1995, 1997)
Cantillo-Ciau (2001, 2003), Delaporte et al. (2004),
Delaporte & Laverde (2006), and Lowe et al. (2012a,
2013c) confirmed the presence of cycloartanes
triterpenoids in Tillandsia species. Also, Wollenberger
et al. (1992), Queiroga et al. (2004), Delaporte et al.
(2006) as well as Lowe et al. (2014c), reported the
presence of phenolic compounds in different
Tillandsia plants (Table No. 2). The chemical
properties confirmed into the genus also permitted
delving in the knowledge of its biological effects,
supporting several of its traditional medical use (Table
No. 3).

have satisfied the use of several experimental models
for its study. Mainly, in vitro (microbicide, antiviral
and cytotoxic) and in vivo (hypoglycemic, anticancer,
and anti-inflammatory), whereas clinical studies there
are not yet available. Table No. 3 enlists the
ethnobotanic data and primary pharmacological
studies in distinct Tillandsia species in order of
importance. In Table 4, the similar studies that have
been carried out with different Tillandsia species are
listed. Weld (1945) and Webber et al. (1952) reported
a flavonol-type glycoside as microbicide agent from T.
usneoides extracts. Also, Feurt & Fox (1952) indicated
the effect estrogenic of eight species of Tillandsia,
which induced estrus in male rats (two to the last row
in Table 2). Posteriorly, Williams (1978) observed in a
wide variety of Tillandsia species the presence of
quercetin and flavonols hydroxylated, among other
compounds, which are enlisted in the Table No. 4.
Keller et al. (1981) and Medon et al. (1985)
reported the hypoglycemic effect of T. usneoides in
rats. Simultaneously, Ulubelen & Mabry (1982),
Arslanian et al. (1986) and Siegel et al. (1987)
reported poly-hydroxylated flavonoids isolated from T.
purpurea, T. fasciculata, and T. utriculata (Table 2).

presence of mercury vapors, which incremented the
peroxidase activity.
Witherup et al. (1995) confirmed the use of T.
usneoides against diabetes, being the 3-hydroxy-3-
methyl glutaric acid (HMG), the molecule active
(Table No. 3). Cantillo-Ciau (2003) and Vite-Posadas
et al. (2011) retaken the pharmacological study of the
plants of the Tillandsia genus (Weld 1945 and Webber
et al., 1952) as a microbicide in human pathogen
organisms (Cantillo-Ciau et al., 2003; Vite-Posadas et
al., 2011). Cantillo-Ciau et al. (2001) also reported the
compounds 60-64 from T. brachycaulos. Delaporte et
al. (2004) reported several compounds from T.
streptocarpa (cycloartenol, 4',5-dihydroxy-3',7-
dimethoxyflavone, and compounds 26-28), which is
used in medicine traditional as analgesic and anti-
inflammatory, which inhibited the ear edema in the rat.
In both cases existed a positive correlation between the
traditional uses of this plant and the experimental data.
Posteriorly, Andrighetti-Fröhner et al. (2005)
reported the antiviral activity (HSV-1) of polyphenol
compounds from T. usneoides, which in traditional
medicine was indicated for the treatment of
ophthalmic illnesses, again validating the relationship
between conventional use and experimental data. The
molecules in T. buseri, β-sitosterol, 4-
methylcholesterol, and lanosterol, showed utility as
biomarkers for the reconstruction of vegetation in the
past (Jansen et al., 2007). More recently, Lowe et al.
(2008, 2012a, 2013b, 2014a) reported T. recurvata
organic extracts against leukemia and prostate cancer
that is the sixth leading cause of death in men
(Stennett & White 2013), conferring biological activity
to the cycloartane triterpenes, to the phenolics
compounds and the soyasaponin molecule (compounds
68-101).
On the other context, it was also reported that
a fungus (Xylariaceae sp.), which is a host of T.
usneoides, synthesizes cytochalasin, a metabolite with
cytotoxic effect in human tumor cell lines (Xu et al.,
2015). Also, 1,3-di-O-cinnamoyl-glycerol failed as an
anticancer drug, which was isolated from CHCl3
extract, although this extract if it was active,
Therefore, other compounds in the extract. Also,
several derivates by hemisynthesis were obtained
which also were studied (Table No. 2).
Thus, T. usneoides and T. recurvata are the
plants most studied of the Tillandsia genus; however,
other Tillandsia species exhibited a similar chemical
content as well as biological effects of interest, such as
anti-diabetic, bactericide, microbicide, anti-
inflammatory, antiviral, and anti-cancer, which should
be studied in depth including clinical studies.
Therefore, the future is promising for exploring more
biological effects of other Tillandsia plants against
various diseases.
Some other medical applications of Tillandsia
plants, particularly of T. usneoides, have been
practiced since the mid-twentieth century. Dean (1943)
and Metzger (1943) reported that extracts of T.
usneoides possessed antigenic properties against
rhinitis and asthma, without an allergic reaction.
Nowadays, many Chinese medicinal preparations
based in T. usneoides as post-treatment in craniotomy
surgery (Lin, 2013), post-dural puncture headache (Li
& Cui, 2013) and hiatal hernia (Wang, 2013) have
been proposed. In addition, a method to obtain nucleus
in suspension for investigation from Tillandsia plants
was proposed (Jin et al., 2014), including the use of T.
recurvata in processes of harvesting, packaging,
transportation, and production of capsules and tablets,
and as an alternative medicament against AIDS-related
diseases (Aizpurua, 1998).
Tillandsia genus: the future
The future of Tillandsia research is uncertain and
paradoxically disastrous in many Latin-American
countries. For instance, in Mexico, particularly in
some communities at Queretaro, State of Mexico and
Veracruz, the people responsible for the care of the
Protected Natural Areas depleted the Tillandsia plants
due to the erroneous conception of that are parasitic
plants. Fortunately, nowadays we are proposing as a
strategy the environmental education, to give more
diffusion of the ecological, medicinal, social,
economic and cultural importance of the plants of the
Tillandsia genus. For instance, there are communities
in which the care of Tillandsia species is a priority, as
at Santa Catarina Ixtepeji and the community of ‘El
Mandimbo’ in San Miguel del Puerto, Oaxaca,
México. In these localities, native people under the
tutelage of their traditional uses and customs, and their
forests protect these plants against pillage and the
deforestation. The acquisition of natural resources
requires official permission. The goal will be to stop
the harmful practices with this resource, which is
relevant worldwide.
T. usneoides and T. recurvata also can have
utility as atmospheric indicators (Wherry and Capen,
1928). Brazil and Mexico reported the efficiency of T.
usneoides for this purpose (Cardoso-Gustavson et al.,
2016; Castañeda et al., 2016). T. velutina Ehlers also is

a good indicator of atmospheric pollutant
formaldehyde (Li et al., 2015). The study of the
Tillandsia genus as an indicator of environmental
pollutants is a topic of high relevance that should be
considered in further studies.

CONCLUSION
Tillandsia genus was used in ancient times as fiber in
pottery. Nowadays it is mainly used as ornamental and
as a medicinal remedy in Latin America. Also, as part
of the rituals in some communities, even too as raw
material for products of use to polish. Tillandsia genus
has economic importance in emerging markets as well
as is utilized in cosmetics products. From the chemical
point of view, more than 40 compounds in 24
Tillandsia species have been proposed, such as
cycloartane triterpenes and hydroxyflavones as
majoritarian metabolites. Several compounds have
been associated with biological activity: HMG as a
hypoglycemic agent, polyphenols as antiviral and
antioxidant properties, soyasaponin I and Cycloartane-
3,24,25-triol, as anticancer agents, among others.
Several compounds and extracts have been associated
with biological activities that are promissory for the
treatment of distinct disease conditions, like metabolic
syndrome, cancer, AIDS, mycosis, and other
infectious diseases. However, only around 10% of
Tillandsia species has been explored, which makes the
future of research for this genre promising. Tillandsia
genus exhibits cultural, economic and pharmacological
relevance, with good potential in many essential
aspects of the modern society.

... Este grupo exhibe una gran diversidad de hábitats y representa la tercera familia botánica más importante de monocotiledóneas mexicanas (Pulido-Esparza et al., 2004). Tillandsia usneoides, pertenece a la familia de las Bromeliáceas, que comprende de 649 especies, popularmente conocida en distintas regiones de México como heno o pascle, es una planta epífita que habita de forma independiente: en el suelo, árboles, sustratos inertes e incluso en cables de líneas eléctricas (Espejo-Serna y López-Ferrari, 2018;Estrella-Parra et al., 2019). En estas especies, la falta de un sistema radicular absorbente se compensa con una estructura especializada llamada tricoma, esencial para la absorción de agua y otros nutrientes (Papini et al., 2011). ...
... Los compuestos de las plantas del género Tillandsia han sido extraídos mayormente de extractos orgánicos, especialmente alcohólicos (metanol y etanol), aunque también se han empleado solventes como acetona, cloroformo, hexano y benceno. Además, algunos extractos han sido investigados utilizando fluido supercrítico de CO2, mientras que los compuestos presentes en extractos acuosos han recibido menos atención (Estrella-Parra et al., 2019). ...
... Los principales compuestos en el género Tillandsia son flavonoides, triterpenoides, ácidos cinámicos, también han sido reportados alcaloides, cumarinas y glucósidos (Vasconcelos et al., 2013;Lowe et al., 2014;Estrella-Parra et al., 2019). Estos compuestos han demostrado actividades biológicas como agente hipoglucémico, antitumoral, antimicrobiana, antiinflamatoria, antivirulencia y antialérgicas (Vite-Posadas et al., 2011;Espejo-Serna y López-Ferrari, 2018;Lasso et al., 2022). ...

La identificación de compuestos bioactivos en plantas es esencial para el desarrollo de nuevos productos farmacéuticos y nutracéuticos. El objetivo de esta investigación fue la caracterización fitoquímica y actividad biológica de extractos de Tillandsia usneoidesrecolectadas en Córdoba y Tetelzingo. Se realizaron pruebas fitoquímicas para identificar metabolitos secundarios presentes en los extractos. La actividad antioxidante se evaluó mediante ensayos de inhibición de radicales libres, y la citotoxicidad se determinó usando un bioensayo de letalidad en nauplios de Artemia salina.Los análisis fitoquímicos revelaron la presencia de alcaloides y glucósidos en el extracto etanólico de Córdoba, mientras que el extracto acuoso mostró una alta concentración de flavonoides. En Tetelzingo, el extracto etanólico presentó una alta concentración de taninos y glucósidos, y el extracto acuoso en flavonoides. La actividad antioxidante fue significativamente mayor en el extracto acuoso de Córdoba (72.09%) en comparación con el extracto etanólico (37.33%). En Tetelzingo, el extracto etanólico mostró una mayor actividad antioxidante (46.94%) que el extracto acuoso (30.04%). Los ensayos de citotoxicidad indicaron que ambos extractos presentaron una toxicidad moderada, con valores de CL50superiores a 100 μg mL-1, mientras que el control positivo mostró alta toxicidad (CL50de 15.58 μg mL-1).
... 7,11,12 The Tillandsia genus has shown some potentialities in pharmacy as a medicinal plant. 13,14 More than 30 Tillandsia species have been mentioned in traditional Mexican medicine, and this has been reviewed recently by Estrella-Parra et al. in a comprehensive and pluridisciplinary approach including ethnobotany, chemistry, biological activity, and economic issues. 14 Uses in traditional medicine have led researchers to investigate the biological properties of compounds isolated from the extracts of Tillandsia species like Tillandsia streptocarpa (Baker), Tillandsia recurvata, Tillandsia usneoides, Tillandsia aeranthos, and Tillandsia brachycaulos, among others. ...

This allowed to demonstrate the presence of several secondary metabolites, of which the major ones are triterpenoids and sterols (51%), flavonoids (45%), and cinnamic acids (4%), obtained from the organic extracts and presenting a wide range of biological activities such as antimicrobial, antiviral, antiherpetic, antiinflammatory, antibacterial, hypoglycemic, and anticancer activities. ...

Plants are an everlasting inspiration source of biologically active compounds. Among these medicinal plants, the biological activity of extracts from some species of the Tillandsia genus has been studied, but the phytochemistry of the hardy species Tillandsia bergeri remains unknown. The aim of the present study was to perform the first phytochemical study of T. bergeri and to identify the compounds responsible for the antibacterial activity of T. bergeri extracts. Soxhlet extraction of predried and grinded leaves was first performed using four increasing polarity solvents. A bio-guided fractionation was performed using agar overlay bioautography as a screening method against 12 Gram-positive, Gram-negative, sensitive, and resistant bacterial strains. The results showed the inhibition of Gram-positive methicillin-sensitive Staphylococcus aureus ATCC 29213 (MSSA), methicillin-resistant S. aureus N-SARM-1 (MRSA), and Staphylococcus caprae ATCC 35538 by the dichloromethane fraction. A phytochemical investigation led to the isolation and identification by high-resolution mass spectrometry and nuclear magnetic resonance of the two flavones penduletin and viscosine, responsible for this antibacterial activity. For viscosine, the minimum inhibitory concentration (MIC) value is equal to 128 μg/mL against MSSA and is equal to 256 μg/mL against MRSA and S. caprae. The combination of these compounds with vancomycin and cloxacillin showed a decrease in MICs of the antibiotics. Penduletin showed synergistic activity when combined with vancomycin against MSSA (FICI < 0.258) and S. caprae (FICI < 0.5). Thus, unexplored Tillandsia species may represent a valuable source for potential antibiotics and adjuvants.
... The genus Tillandsia within the Bromeliaceae family, is categorized as an ornamental succulent in the horticultural industry. Tillandsia species typically grow epiphytically on tree branches or in rock crevices (Estrella-Parra et al., 2019) and are commonly called air plants because of their ability to thrive in soilless environments (Techato et al., 2014). Owing to this unique characteristic, Tillandsia can often be found attached to various artificial structures in urban environments, such as electricity poles, telephone lines, TV antennas, and building exteriors (Piazzetta et al., 2019). ...

In the present study, we aimed to establish an efficient cultivation method for Tillandsia ionantha, which is commonly known as an air plant and is distributed as an ornamental succulent. This species was cultivated using non-substrate cultivation methods in a controlled environment, and the influence of various light spectra on its growth was investigated. The light-emitting diode (LED) light sources used included red (630 nm), green (520 nm), blue (450 nm), purple phyto-LED (450 nm, 650 nm, and far-red wavelengths), warm white (3000 K), natural white (4100 K), and cool white (6500 K) lights. The results showed that shoot length, root length, and leaf width significantly increased under monochromatic blue LED light, highlighting its effectiveness in promoting plant size. In contrast, root and leaf numbers were most effectively enhanced under cool white LED light, highlighting the suitability of broad-spectrum light for balanced root and leaf development. Biomass analysis revealed a growth imbalance between the shoot and root parts, with root biomass being the highest under warm white and cool white LED lights. Red LED light increased relative water content in shoots, indicating its potential for enhancing water retention. Additionally, the external quality of T. ionantha, evaluated using the Commission Internationale de l’Éclairage Lab (CIELAB) color space values, revealed significant changes in leaf coloration under various light spectra. The highest L * value was observed under the natural white LED treatment, whereas the a * and b * parameters varied significantly depending on the light spectra. These findings underscore the importance of light spectrum selection in optimizing T. ionantha various parameters and suggest that a combination of monochromatic and broad-spectrum light can be used complementarily for balanced growth and external quality. This study provides foundational data for the stable cultivation of epiphytic plant species in a controlled environment facility, supporting their broader application in the ornamental plant industry and indoor horticultural projects.
... Epiphytic plants such as Tillandsia from the Bromeliaceae family are rootless and grow by up taking nutrients from the air, the rainwater, and ambient humidity (Estrella-Parra et al. 2019;Eggli and Gouda 2020;. Tillandsia natural habitat can be rainforest with high humidity and temperature, or highlands with wind, cold, and dryness (Bernal et al. 2005;Garth 2015;Sáyago et al. 2018;Miranda et al. 2020;Belmonte et al. 2022). ...

Tillandsia species are plants from the Bromeliaceae family which display biomonitoring capacities in both active and passive modes. The bioaccumulation potential of Tillandsia aeranthos (Loisiel.) Desf. and Tillandsia bergeri Mez acclimated to Southern/Mediterranean Europe has never been studied. More generally, few studies have detailed the maximum accumulation potential of Tillandsia leaves through controlled experiments. The aim of this study is to evaluate the maximum accumulation values of seven metals (Co, Cu, Mn, Ni, Pb, Pt, and Zn) in T. aeranthos and T. bergeri leaves. Plants were immersed in different mono elemental metallic solutions of Co (II), Cu (II), Mn (II), Ni (II), Pb (II), Pt (IV), and Zn (II) ions at different concentrations. In addition, cocktail solutions of these seven metals at different concentrations were prepared to study the main differences and the potential selectivity between metals. After exposure, the content of these metals in the leaves were measured by inductively coupled plasma-optical emission spectrometry. Data sets were evaluated by a fitted regression hyperbola model and principal component analysis, maximum metal loading capacity, and thermodynamic affinity constant were determined. The results showed important differences between the two species, with T. bergeri demonstrating higher capacity and affinity for metals than T. aeranthos. Furthermore, between the seven metals, Pb and Ni showed higher enrichment factors (EF). T. bergeri might be a better bioaccumulator than T. aeranthos with marked selectivity for Pb and Ni, metals of concern in air quality biomonitoring.
... Several activities have been reported for T. usneoides, including microbicide due to the presence of a flavonol-type glycoside; hypoglycemic activity attributed to 3-hydroxy-3methylglutaric acid (HMG), and antiviral activity due to the presence of polyphenols. In addition, other research has reported T. usneoides as anti-hypertensive and active in rheumatism, hemorrhoids, cholagogue, diuretic, renal and ophthalmic illnesses [38]. Other Tillandsia genera exhibit anti-inflammatory and cytotoxic activity in vitro against different tumor cells [39][40][41]. ...

The main limits of current antitumor therapies are chemoresistance, relapses, and toxicity that impair patient quality of life. Therefore, the discovery of therapeutic alternatives, such as adjuvants to conventional therapy that modulate the intracellular oxidation state or the immune response, remains a challenge. Owing to traditional medicine, several uses of plants are known, indicating a promising antitumor and immunomodulatory effect. We evaluated the effect of ethanolic extract of T. usneoides in vitro and in vivo in models of 4T1 breast cancer and B16-F10 melanoma. In vitro evaluations with both cell lines showed that the extract has cytotoxic activity and induces apoptotic cell death. However, its effect on ROS production and glucose uptake was opposite. In vivo, only in the 4T1 model, a significant decrease in tumor size was found in animals treated with the extract, accompanied by an increase in dendritic cells and activated CD8+ T cells, and a decrease in myeloid-derived suppressor-like cells (MDSC-LC) and Tregs in the tumor microenvironment. These results suggest that T. usneoides extract antagonistically regulates tumor metabolism of 4T1 vs. B16-F10, impacting the tumor microenvironment and effective antitumor immune response, leading to a reduction in 4T1 tumor size but not on B16-F10.

Tillandsia is a genus belonging to the Bromeliaceae family, most of which are epiphytes. The flowers of some of the Tillandsia species are very fragrant, but the volatile composition has been scarcely reported. In this report, we studied the chemical composition of volatile compounds emitted by the flowers of Tillandsia xiphioides using the HS-SPME/GC-MS method. The extraction conditions (fiber, temperature, and time) were optimized using a multivariate approach, and the composition of the extracted volatiles was determined by gas chromatography coupled with mass spectrometry (GC-MS). In total, 30 extracted compounds were identified. Two extraction methods are necessary for the efficient extraction of the volatile compounds. These results were applied to profile two forms of T. xiphioides.
... These phytocompounds could be directly involved in the observed cytotoxic activity against both cell lines. In fact, plants of the genus Tillandsia and Ananas (Bromeliaceae) have already been shown to have the ability to synthesize these types of glyceryl HCA derivatives (e.g., 2-O-p-coumaroyl glycerol, 1-O-p-coumaroyl glycerol, and caffeoyl coumaroyl glycerol), which are known to have various biological activities [21,22]. The effects of the extracts of Tillandsia recurvata were shown to have potent effects on PC3 cells (IC50 = 2.4 μg/mL), and this activity was linked with the potent inhibition of protein kinases (Kd = 8-14 μg/mL) that are implicated in cancer growth and proliferation [23]. ...

Preliminary bioassay-guided fractionation was performed to identify cytotoxic compounds from Hechtia glomerata, a plant that is used in Mexican ethnomedicine. Organic and aqueous extracts were prepared from H. glomerata’s leaves and evaluated against two cancer cell lines. The CHCl3/MeOH (1:1) active extract was fractionated, and the resulting fractions were assayed against prostate adenocarcinoma PC3 and breast adenocarcinoma MCF7 cell lines. Active fraction 4 was further analyzed by high-performance liquid chromatography–quadrupole time-of-flight–mass spectrometry analysis to identify its active constituents. Among the compounds that were responsible for the cytotoxic effects of this fraction were flavonoids, phenolic acids, and aromatic compounds, of which p-coumaric acid (p-CA) and its derivatives were abundant. To understand the mechanisms that underlie p-CA cytotoxicity, a microarray assay was performed on PC3 cells that were treated or not with this compound. The results showed that mitogen-activated protein kinases (MAPKs) that regulate many cancer-related pathways were targeted by p-CA, which could be related to the reported effects of reactive oxygen species (ROS). A molecular docking study of p-CA showed that this phenolic acid targeted these protein active sites (MAPK8 and Serine/Threonine protein kinase 3) at the same binding site as their inhibitors. Thus, we hypothesize that p-CA produces ROS, directly affects the MAPK signaling pathway, and consequently causes apoptosis, among other effects. Additionally, p-CA could be used as a platform for the design of new MAPK inhibitors and re-sensitizing agents for resistant cancers.

Numerous volatile organic compounds (VOCs) with a large chemical diversity are emitted by plant flowers. They play an important role in the ecology of plants, such as pollination, defense, adaptation to their environment, and communication with other organisms. The Tillandsia genus belongs to the Bromeliaceae family, and most of them are epiphytes. The aromatic profile of the Tillandsia genus is scarcely described. In this study, we use the headspace solid phase microextraction (HS-SPME) coupled with gas chromatography combined with mass spectrometry (GC-MS) method developed in our laboratory to explore the chemical diversity of the VOCs of fragrant flowers of three species of the genus Tillandsia. We were able to identify, for the first time, 66 volatile compounds (monoterpenes, sesquiterpenes, phenylpropanoids, and other compounds). We identified 30 compounds in T. xiphioides, 47 compounds in T. crocata, and 43 compounds in T. caliginosa. Only seven compounds are present in all the species studied. Comparison of the volatile compounds profiles by principal component analysis (PCA) between T. xiphoides, T. crocata, and T. caliginosa species showed a clear difference in the floral emissions of the studied species. Moreover, floral VOCs profiles allowed to differentiate two forms of T. xiphioides and of T. crocata.

Tillandsia usneoides is an aerial epiphytic bromeliad that absorbs water and nutrients directly from the atmosphere by scales covering its surface. We expanded the use of this species as a broader biomonitor based on chemical and structural markers to detect changes in air quality. The usefulness of such comprehensive approach was tested during the construction and opening of a highway (SP-21) in São Paulo State, Brazil. The biomonitoring study was performed from 2009 to 2012, thus comprising the period during construction and after the highway inauguration. Metal accumulation and structural alterations were assessed, in addition to microscopy analyses to understand the metal chelation in plant tissues and to assess the causes of alterations in the number and shape of scale cells. Altogether, our analyses support the use of this species as a wide biomonitor of air quality in urbanized areas.

The Tillandsia erubescens group (Bromeliaceae) encompasses seven currently recognized species with reduced, pendulous inflorescences and endemic to pine-oak forests in the high mountains of Mexico. During the course of a taxonomic revision based on extensive study of herbarium specimens and detailed observations in the field, a new species of this group was discovered, which is described and illustrated here as T. tecolometl. The new entity belongs to a subgroup of species with purple corollas that also includes T. andrieuxii, T. macdougallii, T. oaxacana and T. pseudooaxacana. We present detailed morphological comparisons of the new species to the other species in the group with purple corollas, complemented with information on their habitat preferences, geographical distribution and phenology. An identification key to all the species with purple corollas belonging to the Tillandsia erubescens group is provided.

Some epiphytic species accumulate airborne particles and are suitable biological indicators for monitoring urban and industrial pollution. The species Tillandsia recurvata L. was studied as a monitor of air pollution in an urban area from Mexico. Individuals were collected in 25 sites which are exposed to different pollution degree and sources. The magnetic particle concentration, particle size, and mineralogy were determined and compared with chemical contents for all samples. The highest values of magnetic concentration dependent parameters were observed in industrial and heavy traffic sites (e.g., mass specific magnetic susceptibility of up to 171.5 × 10 −8 m 3 kg −1). In contrast, sites with low or without vehicular traffic reached low values (e.g., mass specific magnetic susceptibility of down to 1.8 × 10 −8 m 3 kg −1). The integrated magnetic analysis (King's and Day's plots, remanent magnetization parameters and thermomagnetic measurements) revealed the presence of ferromagnetic minerals, mostly magnetite-like with fine grain sizes (0.1–1 ␮m) and subordinate presence of high-coercivity minerals. Selected samples were observed by SEM and EDS analysis and revealed the presence of Fe-rich particles, as well as trace elements, among others, As, Sb, S, Cr, Mo, V, Zn, Ba, Hg, Pt and Cu. Most of the elements detected by EDS were also quantified by ICP-MS measurements. Multivariate statistical analyses prove a high correlation between magnetic parameters and elements, as well as allow us classifying sites in clusters (fuzzy c-means clustering) with different pollution degree. These results demonstrate the usefulness of the species T. recurvata L. as a passive pollution monitor, with an affordable and immediate application. This species is abundant not only in Mexico, but also in other cities from America.

Some species of the genus Tillandsia (Bromeliaceae) are highly endangered in their natural habitats. This report introduces a method for induced lateral shoot development in atmospheric Tillandsias using the cytokinin BAP. Spraying or dipping the plants with BAP-solutions induced many lateral shoots. Even difficult-to-propagate species like T. cacticola L.B.SM developed up to 30 times more usable shoots than the control. Applying low concentrations (1 and 5 mg · L-1) over a longer period of time (10 weeks, 3 times a week) produced results similar to those using higher concentrations (50 mg · L-1) for shorter periods (2 weeks, 3 times a week). Chemical name used: 6-benzylaminopurine (BAP).
