摘 要:采用乙醚为溶剂提取云南产蓝桉干叶的挥发油,经气相-质谱联用仪分析,得到57种组分,确定了其中54个化合物的结构,主要成分是1,8-桉叶素(68.61%),α-蒎烯(10.24%),别香橙烯(5.27%),乙酸松油酯(4.05%),香橙烯(1.45%),(-)-蓝桉醇(1.26%),α-松油醇(1.02%)等。采用峰面积归一法计算各组分的相对含量,所鉴定成分占总馏出峰面积的99.69%。

Abstract:The essential oil was extracted by ether from leaves of Eucalyptus globulus Labill. growed in Yunnan province. The volatile chemical constituents from the herb were identified by GC-MS. Fifty-four volatile components were identified,and its the main compounds were 1,8-eucalyptol(72.71%),α-pinene(9.22%),α-terpineol acetate(3.11%),α-terpineol(2.54%),alloaromadendrene(2.47%). The compounds were quantitatively determined by normalization method,and the identified compounds represented 99.17% of total GC peak areas.
