Abstract
abstract the essential oil from laggera tomentosa sch. bip. ex oliv. et hiern (asteraceae) endemic to ethiopia was investigated by means of gc, gc/ms and nmr spectroscopy. forty-nine compounds constituting 94% of the oil were identified. the oil composition was characterized by a high percentage of oxygenated monoterpenes (78%), the major compound being chrysanthenone (58%). sesquiterpene hydrocarbons constituted 10%, while the monoterpene hydrocarbons and oxygenated sesquiterpenes accounted for 3% each. the high percentage of chrysanthenone and the other main compounds isochrysantenone, filifolone and (z)-isogeranic acid made the composition of the oil markedly different from those of the other species of the genus.
