Phenological Variations in the Content of Polyphenols and Triterpenoids in Herb Originating from Ukraine.

The composition of secondary metabolites undergoes significant changes in plants depending on the growth phase and the influence of environmental factors. Therefore, it is important to determine the harvesting time of plant material for the optimum secondary metabolite profile and therapeutic activity of the primary material. The shoots of are used as a healing tea due to the presence of polyphenolic compounds.

Do Reproductive Traits of Invasive Populations of Scotch Broom, (Fabaceae), Outperform Native Populations?

Reproductive traits are among the most important factors in determining the success of species establishment and invasion in a new area. Studies on transcontinental invasions have revealed that invasive species perform better in the invasive range than in their native ranges. We assumed that the same regularity exists in intracontinental invasions and thus investigated whether the reproductive traits of Scotch broom, , perform better in the alien invasive range in Europe compared to its native range in the same continent.

Study on the Rare Semiaquatic Plant (Elatinaceae) in Lithuania: Population Density, Seed Bank and Conservation Challenges.

Background: Wet, intermittently flooded freshwater coastal and shallow water habitats are notable for their high biodiversity. Many of the usually semiaquatic annuals or small perennials common in such habitats are in decline due to the high sensitivity of such habitats to changes caused by anthropogenic and natural factors. The Euro-Siberian semiaquatic rarely occurs in Lithuania and is protected there and in other Baltic and Central European countries.

(Cyperaceae), a newly-discovered native species in Lithuania: population, habitats and threats.

A previously unrecorded native species, (Cyperaceae), was discovered in the southern part of Lithuania in 2020. Although this species has a large distribution area in other parts of Eurasia, it is currently recognised as threatened in many European countries. Recordings of in Lithuania had been expected, as these plants do occur or have been reported to occur in neighbouring regions.

The Comparative Analysis of Carboxylic Acid Composition of Four Iris Species from Ukraine.

The present article reports results of analysis of carboxylic acids in leaves of Iris species from Ukraine using a gas chromatography (GC) method with mass spectrometric (MS) detection (GC/MS). Carboxylic acids play significant roles in contemporary society as evidenced by multiple applications in fields of medicine, agriculture, pharmacy, food, and other industries. Study of natural plant products as a source of organic acids is of particular interest.

Chemical Composition and Antiproliferative Effect of Essential Oils of Four Solidago Species (S. canadensis, S. gigantea, S. virgaurea and S.×niederederi).

There is a growing interest in the research of natural products with potent activity in the prevention and treatment of diseases. Thereby, essential oil phytochemicals have demonstrated broad bioactivities. This study highlights the chemical composition of essential oils obtained from the leaves and inflorescences of diverse species of the genus Solidago (Solidago canadensis, Solidago gigantea, Solidago virgaurea and Solidago×niederederi), also known as Goldenrod, through GC/MS analysis, and their antiproliferative activity on three human tumor cell lines (MDA-MB 231, A375 and HCT116) by the MTT assay.

Effect of ecological factors on the accumulation of phenolic compounds in Iris species from Latvia, Lithuania and Ukraine.

Introduction: It is important to conduct studies on the influence of environmental factors on the accumulation of secondary metabolites in plants, as well as the cultivation of plants and harvesting of their raw material.

Objective: In this study, we examined the influence of habitat types, soil composition, climatic factors and altitude on the content of phenolic compounds in Iris species from different populations in Latvia, Lithuania and Ukraine.

Methodology: According to high-performance liquid chromatography (HPLC) analysis, 25 compounds (flavonoids, isoflavonoids, isoflavonoid glucosides, xanthones, phenolcarboxylic acids) were identified in the methanol extracts of 16 samples of Iris rhizomes.

(Apocynaceae, Asclepiadoideae): a rare or unrecognized alien species in Europe?

Studies on populations of L. in Lithuania revealed the occurrence of a new alien plant species, the North American native Torr. (Apocynaceae, Asclepiadoideae), in southern parts of Lithuania - the first report of the latter species in Europe.
