RESUMO
The essential oils ofPeucedanum ruthenicum M. Bieb. [Umbelliferae] leaves, flowers and fruits were prepared by hydrodistillation and analyzed by GC and GC-MS and the composition of the three essential oils were compared. Thirty-three, thirty-seven and thirty-one compounds were identified in leaves, flowers and fruits essential oils representing 89.13%, 88.66% and 76.45% of total oils respectively. The major components were thymol [18.29%], B-bisabulene [13.29%] for leaves oil, B-myrcene [10.68%] and germacrene-B [10.06%] for flowers oil and caryophyllene oxide [13.65%] 8, 9-dehydroisolongifolene [11.33%] and 1, 8-cineol [11.15%] for fruits oil. The amounts of monoterpens and sesquiterpenes were found nearly to be equal in oils of the three parts of plant
RESUMO
In this study, 278 species from 37 families of native Iranian plants were screened for in vitro antifungal activity against 19 fungal strains. Initially, the crude extracts in concentration of 100 micro g/ml were tested. Among 278 plant extracts, 201[71.27%] of them showed antifungal activity against at least one fungal strain. A wide range of total extracts of different species were shown to have potentially noticeable antifungal effects. The outstanding species were: Mentha longifolia, Saliva multicaulis, Thymus transcaspicus, Zataria multiflora, Glycyrrhiza glabra, Hulthemia persica, Heracleum persicum, Pimpinella anisum, Pragnos ferulacea, Pragnos uloptera, and Viola odorata
