The resin of Boswellia neglecta yielded four triterpenes canaric acid, α-amyrin, α-amyrone and epi-α-amyrin. Canaric acid and epi-α-amyrin are isolated here for the first time from the family Burseraceae. The compounds were identified using 1D an

Journal of Essential Oil Research. 15:102-105
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 w
