The essential oil of bifora radians bieb.
Water-distilled essential oil from the herb of Bifora radians was analyzed by GC/MS. Twenty nine compounds were characterized representing 99.6% of the oil with (E)-2-tridecenal (47.2%) and (E)-2-tetradecenal (23.4%) as ... -
Ferulagone: A new monoterpene ester from Ferulago thirkeana essential oil
Başer, K. Hüsnü Can; Demirci, Betül; Demirci, Fatih; Hashimoto, T; Asakawa, Y; Noma, Y (Georg Thieme Verlag Kg, 2002)Essential oil obtained by micro-distillation and hydrodistillation of the endemic Ferulago thirkeana (Boiss.) Boiss. (Apiaceae) was analysed by GC/MS. An unknown component isolated from the essential oil was characterized ... -
The microbial oxidation of (-)-beta-pinene by Botrytis cinerea
Farooq, A; Choudhary, M. I.; Tahara, S; Atta-ur-Rahman; Başer, K. Hüsnü Can; Demirci, Fatih (Verlag Z Naturforsch, 2002)(-)-beta-pinene, a flavor and fragrance monoterpene is an important constituent of essential oils of many aromatic plants. It was oxidized by a plant-pathogenic fungus, Botrytis cinerea to afford four metabolites characterized ... -
