Eight collective samples of terminal cymose in¯orescences of Hypericum foliosum Aiton were collected on ®ve islands of the Azores (S. Jorge, S. Miguel, Pico, Terceira and Faial). The essential oils isolated by hydrodistillation to estimate the oil yields, and by distillation±extraction to determine

✦ Synopsis
The volatiles isolated from the leaves and flowers of fnufa viscosa (L.) Ait. were studied by means of GC and GC-MS. The oil obtained by hydrodistillation was shown to contain borneol (25.2%), bornyl acetate (19.5%) and isobornyl acetate (22.5%) as major constituents, whereas that isolated first by hexane extraction followed by hydrodistillation contained borneol (2O.8%), bornyl acetate (48.7%) as main components and a small amount of isobornyl acetate (0.3%).
