| 摘 要： | 以丙酮为提取溶剂,物料粒度为100~200目,料液比1:15,浸泡8 h,萃取时间为1.5 h,在超声功率为80 khz,30℃时对韦塔桉桉叶油进行提取,并用GC-MS对其成分进行分析。结果得到韦塔桉桉叶油的提取率为19.04%,经GC-MS分析得到韦塔桉桉叶油含有10种脂肪酸,其中亚油酸和亚麻酸为不饱和脂肪酸。桉叶油中棕榈酸、亚油酸、亚麻酸及硬脂酸的绝对含量分别为0.82%、0.86%、0.15%、0.33%,占提取粗脂总量的2.16%。

| Abstract: | Extraction of Eucalyptus wetarensis leaf oil was carried out with acetone as solvent,material particle size of 100～200 microns,solvent volume of 150 ml,immersion time of 8 h and extracting time of 1.5 h,in ultrasonic extractor of 80 khz at a temperature of 30℃.The content and components of fatty acids were analyzed by GC-MS.The results showed that the oil extraction rate was 19.04% by dry weight of leaf,and the oil included 10 types of fatty acids including two unsaturated fatty acid： linoleic acid and linolenic acid.The absolute contents of hexadecanoic acid,linoleic acid,linolenic acid and octadecanoic acid in Eucalyptus oils were： 0.82%,0.86%,0.15% and 0.33% respectively,and together fatty acids accounted for 2.16% by weight of the leaf oil. |
