โฆ Synopsis
The leaf oils of Baeckea frutescens L., water-distilled from samples obtained from four dierent sites, were analysed by capillary GC and GCยฑMS. The oils were found to possess some compositional dierences and considerable variation in the levels of each component, suggesting the existence of chemical varieties. The oils were rich in pinenes (39.9ยฑ55.5%), with the exception of one sample which contained g-terpinene at 34.1% as the dominant component. 1,8-Cineole, which was present in appreciable amounts in three samples, was conspicuously absent in one sample. Other compounds that were found as the main components of most of the samples were p-cymene, limonene, linalol, a-terpineol, b-caryophyllene and a-humulene.
