摘　　要：为了对亮叶含笑的精油提取和开发利用提供参考,采用水蒸气蒸馏法,提取亮叶含笑不同器官（叶芽、一年生叶、一年生茎、两年生茎、假种皮、花瓣、雄蕊和雌蕊）中的挥发油,比较其出油率,并运用灰色关联度法对8种精油进行综合品质评价。结果表明：亮叶含笑不同器官精油的平均提取率在0.082%-1.859%,以叶芽的提取率最高,假种皮次之,两年生茎的提取率最低。综合品质以一年生叶的精油最优,花瓣最差。综合比较,亮叶含笑精油提取的材料选择一年生叶最好。The extraction rate of essential oil extracted from different eight organs （leaf bud,annual leaf,annual stem,two-year stem,arillus,petal,stamen and pistil）of M.fulgens Dandy was compared and the integrated quality of eight essential oils was evaluated by gray relational degree to provide a reference for extraction,development and utilization of essential oil extracted from M.fulgens Dandy. The results showed that the average extraction rate of eight essential oils is 0.082% - 1.859% and the extraction rate of essential oil extracted from leaf bud of M.fulgens Dandy is the highest,followed by from arillus,and the extraction rate of essential oil extracted from two-year stem of M.fulgens Dandy is the lowest.The integrated quality of essential oil extracted from annual leaf of M.fulgens Dandy is the best but the integrated quality of essential oil extracted from petal of M.fulgens Dandy is the worst.In conclusion,the suitable material for extracting essential oil from Michelia fulgens Dandy is annual leaf.
