[ 1 ] - Antibacterial Activity of Peucedanum ruthenicum, Johreniopsis seseloides and Cervaria cervariifolia Extracts

       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...

[ 2 ] - New Triterpenoids from Peucedanum ruthenicum

       From hexanic extract of aerial parts of Peucedanum ruthenicum M. Bieb (Apiaceae) collected from Mazandaran province of Iran, four triterpenoids namely taraxasterol, y-taraxasterol, poriferasterol and b-sitosterol have been isolated by column chromatography, thin layer chromatography, and crystallization. Their structures were elucidated by spectroscopic methods (UV, IR, MS, 1H and 13C-N...

[ 3 ] - Chemical Constituents and Antibacterial Activity of Essential Oil of Prangos ferulacea (L.) Lindl. Fruits

      The essential oil of Prangos ferulacea (Apiaceae) fruits was obtained by hydrodistillation and analyzed by gas chromatography (GC) and GC-mass spectrometery (MS). Among the 39 identified constituents accounting for 99.99% of the total oil, the major components were chrysanthenyl acetate (26.53%), limonene (19.59%), alpha pinene (19.50%), delta-3-carene (6.56%), mesitaldehyde (6.0...

[ 4 ] - Chemical Composition of the Essential Oils of Peucedanum ruthenicum (M. Bieb.) Rochel Leaves and Flowers from Kalardasht

     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...
