A rapid and sensitive reversed-phase high-performance liquid chromatographic (RP-HPLC) method has been used for determination of furanocoumarins in methanolic extracts of Peucedanum tauricum Bieb. HPLC separation was performed on a C18 analytical column (250 mm × 4 mm i.d., 5-μm particles) with a methanol–water gradient as mobile phase. A second chromatographic system with an acetonitrile–water...

Members of the genus Centaurea (Asteraceae) have been used in traditional plant-based medicine. The methanol extracts of twelve Centaurea species, of which five are endemic to Turkey flora, were screened for antibacterial activity against four bacteria (Escherichia coli, Bacillus cereus, Salmonella enteritidis, Staphylococcus aureus). The antibacterial activity was evaluated by the microdilutio...

Many of the best-selling anticancer drugs are plant-derived. We tested for the anticancer properties of extracts isolated from Centaurea ainetensis, a plant species endemic to Lebanon and which is often used in folk medicine. We performed bioassay-guided fractionation of Centaurea ainetensis extracts using a panel of normal and neoplastic murine cells to identify a component that is associated ...

Centaurea L. is a genus of the family Asteraceae that comprises over 600 taxa. Representatives of the Centaurea genus were used as natural medications for many diseases. Methanolic-aqueous extracts from aerial parts of two Centaurea species: C. borysthenica Gruner and C. daghestanica (Lipsky) Wagenitz were studied for their polyphenolic composition and potential protective effect on cardiomyocy...

In this study, the growth and fruit characteristics of two species maquis, one Mediterranean were determined. The average individual height Crataegus orientalis Pall. ex M. Bieb. subsp. individuals 2.99 m, crown diameter is 2.13 number branches 2, monogyna Jacq. var. was 3.17 2.35 2.8. While fruits in C. 295.82 weight 1.72-3.37 g, 4274.5 0.33-0.90 g. As a result analysis variance applied to com...

BACKGROUND Biological invasions are fundamentally biogeographic processes that occur over large spatial scales. Interactions with soil microbes can have strong impacts on plant invasions, but how these interactions vary among areas where introduced species are highly invasive vs. naturalized is still unknown. In this study, we examined biogeographic variation in plant-soil microbe interactions ...

Methanol extracts from the leaves of 55 species, belonging to 4 subgenera and 16 subsection genus Euphorbia (Euphorbiaceae) have been screened for presence ellagic acid (EA). EA was quantified by gas chromatography-mass spectrometry (GC-MS) in fresh plant material sp. growing Russia Kyrgyzstan wild indoor outdoor collections Peter Great Botanical Garden Komarov Institute Russian Academy Science...

       Antimicrobial activity of the polar and nonpolar extracts of the roots and aerial parts of Peucedanum ruthenicum M. Bieb., Johreniopsis seseloides (C. A. Mey.) Pimenov and Cervaria cervariifolia (C. A. Mey.) Pimenov were examined against gram-positive and gram-negative bacteria. The polar extracts of the roots and aerial parts displayed no activity against bact...
