The essential oils from the leaves of Laggera alata var. montana C. D. Adams, and Laggera gracilis (O. Hoffm. & Muschl.) C. D. Adams, and those from leaves, roots and stems of Laggera oloptera (DC.) C. D. Adams from the western highlands of Cameroon were analysed by GC and GC-MS. The essential oils of L. alata var. montana and L. gracilis were found to be rich in dimethoxy-p-cymene (34% and 33%, respectively). The other most abundant components in these oils were 7-epi--eudesmol (21%), juniper camphor (7%) for L. alata var. montana and -eudesmol (10%),ˇ-caryophyllene (7%) for L. gracilis. The essential oils from leaves of L. oloptera were found to be poor in dimethoxy-p-cymene (0.1-0.3%) but affordedˇ-caryophyllene (15-20%), germacrene-D (10-17%) and sabinene (2-28%) while the volatile extract from roots and stems were rich in dimethoxy-p-cymene (67% and 36%, respectively) andˇ-caryophyllene (6% and 16%, respectively). The essential oil from the stems also contained a high proportion of -eudesmol (20%).
