Abstract
The chemical composition of three different buchu essential oils which were derived from Agathosma betulina, A. crenulata and an A betulina x crenulata hybrid respectively (fam. Rutaceae) was investigated by means of chromatographic and spectroscopic methods. Approximately 40 compounds, all known, were detected. A. betulina was characterized by 31% of (iso)menthone, 41% (ϕ)-diosphenol and 3% of the olfactory important cis- and trans-8-mercapto-p-menthane-3-ones. The A. crenulata oil contained very high quantities of pulegone (54%) besides considerable quantities of trans-8-acetylthio-p-menthan-3-one (7%). The hybrid showed, apart from a very high concentration of (iso)menthone (55%), an intermediate composition.Keywords
