Immortelle (Helichrysum italicum (Roth) G. Don; Asteraceae) is a perennial plant species native to the Mediterranean region, known for many properties with wide application mainly in perfume and cosmetic industry. A total of 18 wild H. italicum populations systematically sampled along the eastern Adriatic environmental gradient were studied using A...

Olive leaves are a highly available by-product from table olive and olive oil production. They are nowadays strongly valuable for their major bioactive compounds and their beneficial effects. To determine the differences between two Croatian domestic (Lastovka, Oblica) and two introduced (Leccino, Frantoio) cultivars, physical and chemical analysis...

Dalmatian pyrethrum (Tanacetum cinerariifolium /Trevir./ Sch. Bip.) synthesizes secondary metabolite pyrethrin, known for its potent insecticidal and repellent activity. The present study was aimed at optimizing the maceration extraction parameters that improve the efficiency of pyrethrin extraction from the dried Dalmatian pyrethrum flower heads....

Salvia officinalis is a perennial species, native and endemic to the Western Balkans and the Apennine Peninsula. Due to its medicinal and aromatic properties, it is used in pharmaceutical, cosmetic, and food industries. The main objectives of the study were to infer the genetic structure of S. officinalis populations in the northern and central par...

Helichrysum italicum (Roth) G. Don is a thermophilus perennial from family Asteraceae. Due to versatile biological activities and applications, the interest in Helichrysum italicum scientific research and use has increased in the last couple of decades. Consequently, due to the increased industrial demand its plantation farming experienced a huge e...

The essential oil of Helichrysum italicum (Roth) G.Don, commonly known as immortelle, is produced in Mediterranean countries to meet the increasing demand of the cosmetic and pharmaceutical industries. This study focused on the analysis of secondary metabolites, specifically essential oils, extracted from plants grown from the seeds of natural immo...

Sea fennel (Crithmum maritimum L.) is one of the most abundant and widespread Mediterranean halophytes, traditionally harvested and used in the summer months. As the plant bioactive metabolites are strongly influenced by the plant vegetation period and environmental conditions, we investigated some of the main bioactive compounds from sea fennel le...

Background: Dalmatian Zagora has experienced significant depopulation trends over recent decades. The area is very interesting because of its rich biodiversity of species as well as its history of the use of wild foods. Since there is a danger of permanent loss of knowledge on the use of wild edibles, we focused our research on recording traditions...

Extreme environmental conditions affect the synthesis and accumulation of bioactive metabolites in halophytic plants. The aim of this study was to investigate the presence and quantity of key health-promoting phytochemicals in Croatian sea fennel, one of the most popular Mediterranean halophytes with a wide range of uses. The EOs were characterised...

Service tree (Sorbus domestica L.) is a wild fruit species distributed through central and southern Europe, rarely in North Africa, Crimea and Caucasus. In Croatia, service tree typically grows scattered in mixed hardwood forests, in small groups or as a solitary tree, mixed with other species, in agricultural lands, under different environmental c...

The aim of this study was to produce non-fermented preserved sea fennel leaves in different pickle juices prepared with apple cider vinegar, wine vinegar and alcoholic vinegar, and to compare their chemical parameters (pH, titratable acidity and salt content), organoleptic properties (color and texture parameters; volatile aromatic compound profile...

Wild edible Mediterranean herbs have always played an important role in human diet and traditional medicine, and recently special attention has been paid to halophytic species, since about 1% of the total world flora consists of these plants. They are native to saline habitats because of their special adaptive mechanisms to the harsh conditions to...

The main objectives of this study were to investigate the effects of the applied essential oil (EO) isolation method, conventional hydro-distillation (HD), and microwave-assisted hydro-distillation (MHD) on the chemical profile of sea fennel (Crithmum maritimum L.) essential oil and to investigate the main constituents present in the liquid by-prod...

The objective of this study was to evaluate the release rate, duration, and biological efficiency of yeast volatile compounds associated with olive fruit flies in slow-release dispensers, polypropylene vials, and rubber septa attached to yellow sticky traps under different environmental conditions in order to protect the environment, humans, and no...

Plant biodiversity is the basis for sustainable agricultural production. Due to various geographical, climatic and soil conditions, Croatia has a great richness of medicinal and aromatic plants (MAP), whose natural populations show great diversity at the morphological, biochemical and genetic levels. However, they are threatened by genetic erosion...

Dog rose (Rosa canina L.) is a wild fruit species widely distributed in Croatia in forest edges and agricultural areas. This research discusses the morphological variability of the dog rose fruits in the Mediterranean part of Croatia. Fruits were collected in situ, in four different ecological areas: the coastal region (Split and Klis) and the hint...

Even though Olea europaea L. is one of the most important and well-studied crops in the world, embryonic parts of the plants remain largely understudied. In this study, comprehensive phytochemical profiling of olive vegetative buds of two Croatian cultivars, Lastovka and Oblica, was performed with an analysis of essential oils and methanol extracts...

Lavandin (Lavandula × intermedia Emeric ex Loisel.) was brought to the Island of Hvar (Croatia) in the 1920s, coinciding with the beginning of large-scale cultivation of lavandin in France. Although the cultivation of lavandin and the production of essential oils are of great importance worldwide, the genetic diversity of lavandin has been little s...

Leaves play a central role in plant fitness, allowing efficient light capture, gas exchange and thermoregulation, ensuring optimal growing conditions for the plant. Phenotypic variability in leaf shape and size has been linked to environmental heterogeneity and habitat characteristics. Therefore, the study of foliar morphology in plant populations...

Pyrethrin is a specialized metabolite of Dalmatian pyrethrum (Tanacetum cinerariifolium (Trevir.) Sch. Bip.), Asteraceae, known worldwide as an effective bioinsecticide. It consists of six active compounds: Pyrethrin I and II, cinerin I and II, and jasmolin I and II. Pyrethrin accumulates mainly in the flower heads and its content depends on numero...

Dalmatian pyrethrum (Tanacetum cinerariifolium /Trevir./ Sch. Bip.) produces pyrethrin which is currently the most important natural insecticide. Due to the growing interest for its use in organic agriculture, the demand for this valuable plant is increasing. However, poor seed germination and inaccessibility of high quality planting material is on...

Pyrethrin is the secondary metabolite synthesized in Dalmatian pyrethrum (Tanacetum cinerariifolium /Trevir. / Sch. Bip.) and recognized for its potent insecticidal activity with no adverse effects on humans and environment. The natural distribution area of Dalmatian pyrethrum expands throughout the Eastern Adriatic coast and the islands. Today, as...

Dalmatian sage (Salvia officinalis L.) represents one of the most significant medicinal autochthonous species in flora of eastern Adriatic coast and islands. It is evergreen outcrossing perennial subshrub with short woody stems that branch extensively and violet flowers. Apart from being native to Mediterranean karst of west Balkan and Apenine peni...
