Sesquiterpene Hydrocarbons in Glandular Trichome Exudate of Rosa rugosa Leaves

From glandular trichome o f Rosa rugosa, three major sesquiterpene hydrocarbons [acora3(4),7(15)-diene, carota-4(5),ll(12)-diene (isodaucene) and carota-l,4-diene], and two minor [daucene and acora-3(4),7(8)-diene] were identified. The presence o f these carotadienes, which are possibly precursors o f the corresponding C-14-oxygenated carotanoids, suggested that the formation o f the carotane s...
