The essential oils of leaves and flowers of Peucedanum ruthenicum (M. Bieb.) Rochel (Umbelliferae) were prepared by hydrodistillation separately and analyzed by GC and GC-MS, and the composition of both essential oils were compared together. Sixteen and eleven compounds were identified in leaves and flowers essential oils representing 100% and 96.4% of total oils, respectively. Th...

In the search for novel herbal-based anticancer agents, we isolated a new angular-type pyranocoumarin, (+)-cis-(3'S,4'S)-3'-angeloyl-4'-tigloylkhellactone (1) along with 12 pyranocoumarins (2-13), two furanocoumarins (14, 15), and a polyacetylene (16) were isolated from the roots of Peucedanum praeruptorum using chromatographic separation methods. The structures of the compounds were determined...

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 bacteria, while the nonoplar extracts ...

Widespread worldwide Peucedanum plants (Apiaceae) have been used for centuries as plant medicines. The polymorphism of this genus is consistent with chemotaxonomically and therapeutically significant differences in the composition secondary metabolites. GC-MS tauricum M.B. volatiles from headspace (HS) hydrodistilled essential oil (HD), both obtained simultaneously flowers (FL), immature ripe f...
