We isolated and examined a new Alternaria sp., which causes leaf spots on Peucedanum japonicum in Korea, by using molecular and morphological methods. Phylogenetic analysis based on a combined internal transcribed spacer region analysis and two protein-coding genes (gpd and Alt a1) demonstrated that the causal fungus was most closely related to A. cinerariae and A. sonchi, and relevant to A. br...

       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...

from methanolic extract of aerial parts of peucedanum ruthenicum m. bieb (apiaceae) collected from mazandaran province of iran, four flavonoids namely isorhamnetin 3-0-rutinoside 1, rutin 2, quercetin 3, morin 4 and two phenolic acids namely caffeic acid 5 and p-coumaric acid 6 have been isolated by paper chromatography (pc) and crystallization. their structures were elucidated by ms, 1h, 13c n...

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. the major compon...
