Terminalia chebula
Retz. well-known species of
family Combretaceae is commonly known as
Chebulic Myrobalan and ‘
in Sanskrit. It is
an important plant in both, Indian as well as Korean
and Chinese traditional medicine (Lee
et al.
Bark powder is gargled in water as a dentifrice to
treat toothache and bleeding gums, as well as
chronic ulcers (Singh
et al.
2002). Fruits are common
constituent of ‘
’, capable of imparting
youthful vitality and receptivity of mind and sense
et al.
1990; Sharma 1995 and Kochhar 1998).
It is a major constituent in the Ayurvedic preparations
Abhayarishta, Abhayamodak, Haritakikhand,
. In
Allopathy, it is used in astringent ointments. In
Unani system, it is used as a blood purifier. The
pulp of the fruit is given in piles, chronic diarrhoea,
dysentery, costiveness, flatulence, asthma, urinary
disorders, vomiting, hiccup, intestinal worms and
enlarged spleen and liver (Cheng 2002, Masoko &
Eloff 2007). Powder of the fruits is used in chronic
ulcers and wounds, carious teeth and bleeding
ulceration of the gums. Fruits are used for diabetes,
fever and anemia (Daniel 2005). Bark and fruits are
good cardiac tonic and laxative (Singh
et al.
’ is used in biliousness, hemorrhoids,
enlarged liver and other disorders. The kernel oil is
applied to hairs and to rheumatic swellings, mixed
with honey, fruit pulp is employed in ophthalmia
et al.
1998). Fruits are astringent (Masoko &
Eloff 2007). Finely powdered fruits are also used as
dentifrice and considered useful in various teeth
bleeding and ulceration of gums (Jain 1994 and
Sharma 1995). The fruits are valuable for tannins
and dyes. The wood is used for building purposes,
agricultural implements, ply-wood and in match box
industry. It is also grown as a shade tree (Joy
et al.
1998; Joshi 2002; Khare 2007 and Trivedi 2008), also
for cabinet work, furniture and interior fitting
(Sambamurty 2005). This plant is also used as fodder
(Anonymous 1909 and Kumar & Bhatt 2006).
T. chebula
Retz. occurs typically in dry
deciduous forests and favoring clay soil, up to 1450
m in southern India, 450 m in Central India, 200 m
in Western India, 500 m in North East India, 1500 m
in Himalaya and 1050 m in Myanmar. It is also
reported from Sri Lanka and Bangladesh and
cultivated elsewhere.
Materials and Methods
The plant parts were collected from the tree
planted in Milind College of Science, Aurangabad
(MS), Field no.7073, Latitude N 19o53'17'', Longitude
E 075o18' 79'', altitude 600 m. Transverse sections (T.
S.), tangential longitudinal sections (T. L. S.) and
radial longitudinal sections (R. L. S.) of wood,
transverse sections of bark, leaves and petioles were
taken by free hand method with the help of razors.
Sections were double stained and permanently
mounted. The bark, wood and leaves were macerated
by Jeffery’s method (Khandelwal 2006). Trichomes
were studied by scrapping. The dimensions were
measured and microphotographs were taken by
Motic Microscope with image processing software.

According to its commercial interest, there are several studies on wood characteristics of the genus with some attempts to differentiate between Terminalia species (Metcalfe and Chalk, 1950;Normand and Paquis, 1976;van Vliet, 1979;Rajput and Rao, 1999;Tilney, 2002;Gupta and Singh, 2005;Singh and Sharma, 2013;Ingle and Dhabe, 2015). Despite all previous wood studies, Terminalia, in general, vary significantly in morphology, anatomy, and karyotype characters (Gill et al., 1982;AL-Mayah, 1983;Jansen et al., 1995;Ohri 1996;Schmidt and McCleland 2002;Sarkar et al., 2016). ...
... His detailed description of wood elements is typical to that of the current study except for ray cell arrangement that was stated as mostly multiseriate and occasionally uniseriate in T. catappa. Moreover, these anatomical stem characters were similar to those observed in T. chebula by Ingle and Dhabe (2015). On the contrary, this study slightly differs from that of Singh and Sharma (2013), who concerned about the composition of rays forming of procumbent cells except for T. arjuna; rays were heterocellular and were composed of both procumbent and square cells. ...

A comparative investigation of the anatomical characters through a microscopical examination of the prepared transverse sections of the stem was carried out. Six plates with 32 photomicrographs were provided to convincingly show the considerable variations of anatomical characters within the nine examined species. The matrix of 18 anatomical characters which included nine quantitative and nine qualitative was applied for the clustering analysis (CA) followed by the principal component analysis (PCA) using the Multivariate Analysis of Ecological Data, PC-ORD. The results exhibited significant variations among the species resulting in the construction of an artificial key; this key accurately represents a sufficient tool to display the considerable variation among the recognized species prominently. The distinction between Terminalia L., 1767 species based on significant variations in the elements of stem anatomy; axial parenchyma and ray characteristics were considered as important parameters, while vessel diameter, fiber wall thickness, etc. were considered minor characters to differentiate between the studied species. The potential usefulness of the differentiation of these species properly maintains a profound efficiency in pharmaceutical and traditional medicine.

Background: The fruit pulp of T. chebula and S. jambolanum seeds are used for treatment of various body ailments and have key part of complementary and alternative medicine since ancient time. Aims: This study was designed to lay down the pharmacognostic, phytochemical and HPTLC features of the fruit pulp of T. chebula and the seed of S. jambolanum which may be useful to establish the micro-morphology, quality, purity, safety and efficacy of selected medicinal plants. Methods: Numerous methods including macroscopic, microscopic, phytochemical and HPTLC assay were applied to describe the diagnostic features for the identification and standardization of fruit pulp of T. chebula and S. jambolanum seeds. Results: Microscopic study of S. jambolanum reveals the presence of scattered vascular bundles, tegmen consisting brachysclereids and macrosclereids with broad and narrow lumen. Whereas T. chebula shows the fragment of epidermis with epicarp, fragments of parenchymatous cell fragment of rosette crystal. Preliminary phytochemical screening detects the different compounds viz., carbohydrates, proteins, amino acids, steroids, glycosides, alkaloids, tannins and phenolic compounds. HPTLC 3D densitogram at 270 nm shows comparative Rf value of comparable to samples with standard value and derivatization with sample as that of standard at Rf value 0.78 for gallic acid equal to T. chebula and Rf value 0.41gallic acid equal to S. jambolanum extract. Conclusions: Various pharmacognostical characters were observed in this study can be an evidence of the effective and standardized method of HPTLC analysis which is simple, rapid, precise and Prajapati et al. 32 accurate to further research these medicinal plants. Meanwhile, the results of this paper deal with pharmacognostical and HPTLC finger print analysis on the T. chebula and S. jambolanum in an attempt to mitigate the adulteration of the crude drug.

Pterocarpus angolensis and Terminalia sericea are two African species with medicinal potential. Despite the importance of their bark as a powerful astringent to treat various diseases it is poor described. In order to provide referential information for correct identification and standardization of the plant material, bark samples from each two species were collected and analyzed under light and electron microscopy. Some important anatomical features to identification were: the sclerenchyma tissue mostly in form of fibre-sclereids and the large secretory cells arranged in conspicuous rows or tangential bands in the conducting phloem in P. angolensis; the crystalliferous cells arranged in very regular tangential rows (druses) and the occurrence of large crystal cells near or including the tangential fibre bundles in T. sericea bark.The results obtained show that the anatomy of the bark can be used as an important subsidy in identification and standardization of the studied species contributing the scientific knowledge for more effective forms of scrutiny in preventing commercial adulteration of species.
Leaf (midrib and lamina) anatomical characters were investigated to enhance the identification of Terminalia L. The central portions of the mature leaves were fixed in formaldehyde, glacial acetic acid, and ethanol (FAA) for 12 hrs. They were dehydrated in alcohol series, hand-sectioned, stained with safranin and alcian blue, mounted on a slide, viewed, and photographed with Optika B-1000 FL LED fitted with digital camera. Our findings showed the absence of rib trace in T. ivorensis, presence of secretory ducts in T. catappa, open vascular cylinder with incurved ends in T. mantaly, and medullary phloem in T. avicenniodes. These characters were key to the delimitation of the Terminalia species.

The traditional systems of medicine are really effective but the problem with them is they lack in quality assurance. Standardization is the need of the hour in ayurvedic system of medicine. PanchaHarithakadi Churna (PHC) is a traditional polyherbal formulation which consists of five household ingredients used for indigestion. It is mainly used for Constipation and Bloating. Churna’s will play a major role in gastro intestinal problems and they have greater bioavailability because of smaller particle size. It consists of fine powder (sieve 100 size) of ginger rhizomes, fennel fruits, myrobalan fruits, senna leaflets and pink rock salt in equal proportions (1:1:1:1:1) are mixed well. PHC was formulated by standard procedures and evaluated by microscopic characterization, inorganic analysis and digestive studies. Microscopical characters indicate the presence of genuine crude drugs used in the formulation. Inorganic analysis shows the presence of calcium, magnesium, sodium, chloride and phosphate. The PHC showed pronounced amylolytic activity and trypsin activity whereas moderate lipolytic activity, proteolytic activity and pepsin activity, mild chymotrypsin activity in treating indigestion. In future we will carry out in vivo digestive studies.

TERMINALIA in Egypt is represented by nine species. The locations of the different collected species were georeferenced with a GPS device. The samples were identified at the Cairo University Herbarium (CAI). Anatomical sections were investigated with a light microscope; Olympus BX51. Photomicrographs were taken using photomicroscope; Olympus DP12. Twenty-four anatomical characters have significant diversity. In leaf, type of mesophyll, length of palisade tissue, number and size of the main and accessory vascular bundles, presence or absence of vascular bundles in small veins as well as lysigenous ducts and crystals. In petiole, the number, shape and distribution of the main and accessory vascular bundles, types of bundle sheath, number of lysigenous ducts, etc. Qualitative and quantitative data of the anatomical characters have been investigated through numerical method by using the unweighted pair group method with arithmetic mean (UPGMA). An artificial key was constructed that could be a taxonomic delimitation for comparison between species. This Study proposed that anatomical features of leaf lamina and petiole of Terminalia species investigated should be used as an effective delimitation for authentication and differentiation between the species.

This report deals with 64 species of plants belonging to 42 families and 57 genera. The plants discussed are all used as medicine among ethnic groups in Sikkim. Important ail- ments purportedly cured by these plants are epilepsy, leprosy, paralysis, asthma, typhoid, diabetes, hemorrhages during childbirth, cholera, as well as others. Some of these plants are also used as food items and play a significant role in the rural economy. A few of these medicinal plants are believed among ethnic people to prolong life and are part of local tradition. Though allopathic medicines are in vogue, herbal medicinal practition- ers do a brisk business. The herbals in the region are in danger of economic exploitation by the rural folk as well as commercial collectors. In order to conserve these important resources, management options, including the cultivating of medicinal plants, should be explored.

The dried leaves of Combretum and Terminalia species (Combretaceae) were extracted with acetone, hexane, dichloromethane and methanol. Thin layer chromatography (TLC) plates were developed under saturated conditions and sprayed with 0.2% 2,2-diphenyl-1-picryl hydrazyl (DPPH) in methanol for antioxidant screening. Visualization of separated bands exhibiting antioxidant activities enabled the localization and the subsequent identification of the potential active compounds. The acetone and methanol extracts displayed the presence of antioxidant activity after spraying the chromatogram with DPPH. Hexane and dichloromethane extracts did not have any antioxidant activity. C. hereroense had the highest number of active compounds, followed by C. collinum ssp. taborense, which were 16 and 10, respectively. Acetone extracts of all tested Combretum species had 53 active bands and methanol had 55. All Terminalia species extracted with acetone and methanol had antioxidant activity. T. gazensis and T. mollis methanol extracts had 11 and 14 active compounds respectively in one of the solvent systems used. The qualitative DPPH assay on TLC was successfully used in this study to systematically assess the total antioxidant activity of the Combretum and Terminalia species extracts.
The selection of plants studied in this treatise is based on its significance, and its representation of members of different taxonomic families as well as of different classes (and subclasses) of compounds. All the available data on the chemical compounds and the pharmacological studies on these plants/compounds have been incorporated. The plants are arranged by the type and nature of chemical compounds they contain. Secondary metabolites have been included in this volume due to their great therapeutic role.
The cytotoxicity-directed fractionation of MeOH extract ofTerminalia chebula fruits led to the isolation of three hydrolyzed tannins and a related compound, gallic acid(I), 1,2,3,4,6-penta-O-galloyl-β- d -glucopyranose(II), chebulagic acid(III) and chebulinic acid(IV), as active principles. They were shown to exhibit moderate cytotoxicity against cultured human tumor cell lines including A-549, SK-OV-3, SK-MEL-2, XF-498 and HCT-15in vitro.
The major portion of the local population which is economically depressed is scattered in different hill terrains, which are beyond the normal mode of approach. Sometimes it takes days to reach remote corners of the country, where the usual supply of allopathic medicine is out of the question. Due to increasing export demand, dependence of the local people on the herbal flora and their implicit faith in the old tradition of Ayurvedic medicine would go a long way in exploiting the wild plants for commercial return and in expanding research activities to gain productive results. It is reported that in the sixth and fifth centuries B.C., in the course of his survey, Jivaka, the Royal Physician during Buddha’s time, examined all the plants growing in the specified area around Taxila (Pakistan) and concluded that there was not a single plant which could be considered devoid of medicinal utilization (5). These observations are of special significance for the rich herbal flora of Nepal, which has tremendous need for critical scientific examination. It may be concluded that the inside knowledge of herbal therapy for the healing of humanity is the vital part these mysterious herbal plants have now to play, and it can be hoped that their contributions would be of great practical importance.
Casuarinin, a hydrolyzable tannin isolated from the bark of Terminalia arjuna Linn. (Combretaceae), was investigated for its antiviral activity on herpes simplex type 2 (HSV-2) in vitro. Results showed that the IC(50) of casuarinin in XTT and plaque reduction assays were 3.6+/-0.9 and 1.5+/-0.2 microM, respectively. The 50% cytotoxic concentration for cell growth (CC(50)) was 89+/-1 microM. Thus, the selectivity index (SI) (ratio of CC(50) to IC(50)) of casuarinin was 25 and 59 for XTT and plaque reduction assays, respectively. Casuarinin continued to exhibit antiviral activity even added 12 h after infection. During the attachment assay, casuarinin was shown to prevent the attachment of HSV-2 to cells. Furthermore, casuarinin also exhibited an activity in inhibiting the viral penetration. Interestingly, casuarinin was virucidal at a concentration of 25 microM, reducing viral titers up to 100,000-fold. This study concludes that casuarinin possesses anti-herpesvirus activity in inhibiting viral attachment and penetration, and also disturbing the late event(s) of infection.
