【 摘 要 】

Essential oils from fresh leaves ofSclerocarya birrea(A. Rich.) Hochst.were extracted by steam distillation. The oil yield from plant collected during the hot season (February) was 0.10±0.02 and 0.24±0.01% from plant collected during the cold season (August). GC/FID and GC/MS analysis allowed us to identify a total of 49 compounds,representing 98% of the hydrodistillate.The oils contained about 96% sesquiterpenes among which 38±0.034% of 7-epi-α-selinene during the hot season and 51.7±0.12% of 7-epi-α- selinene during the cold.The main components of the oil from thehot period were 7-epi-α-selinene(38±0.03%),α-muurolene(25±0.03%),valencene(17±0.06%),β-selinene (4.3±0.01), β-caryophyllene(3.2±0.02)allo-aromadendrene-epoxide (1.5±0.03) and 14-hydrox-α-humulene (1.5±0.03). The essential oil from the coldseason was characterized by 7-epi-α-selinene(51.7±0.12%),β-selinene (15.1±0.2%),valencene(12.9±0.05%),α-selinene (8.1±0.03) andβ-caryophyllene (1.8±0.02%). This is the first report of these components in the essential oil ofSclerocarya birrea.
