Chemical composition of the essential oils ofpeucedanum ruthenicum m. bieb. leaves, flowers and fruits

ABSTRACT

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
