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‐γ‐ eudesmol (21%), juniper camphor (7%) for L. alata var. montana and γ‐eudesmol (10%), β‐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 afforded β‐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) and β‐caryophyllene (6% and 16%, respectively). The essential oil from the stems also contained a high proportion of γ‐eudesmol (20%). Copyright © 2002 John Wiley & Sons, Ltd.
