摘　　要：采用水蒸气蒸馏法分别提取云南两个薰衣草品种（CAS07和CAS08）鲜花及干花精油，然后经GC—MS分析其化学成分，并用峰面积归一法确定其相对含量。结果表明，CAS07鲜、干花的得油率分别为2．2％和2．7％，CAS08鲜、干花的得油率分别为3．3％和3．8％，两个不同品种间的薰衣草精油得油率表现出极显著差异（P〈0．01），同-品种鲜、干花得油率无显著性差异（P〉0．05）；CAS07薰衣草精油中的主要化合物有：芳樟醇（38．58％～39．16％）、乙酸芳樟酯（21．80％～26．71％）和乙酸薰衣草酯（7．69％-13．15％）；CAS08薰衣草精油中的主要化合物有：桉叶油醇（49．70％-49．80％）、樟脑（13．64％～14．26％）、0L-红没药醇（6．62％-7．65％）。本研究结果发现鲜花采收后及时加工比于花加工提取精油产量更高，精油品质更好；可为云南薰衣草产业化发展决策提供理论科学依据，并为建设美丽家庭农场及特色生态庄园提供参考与借鉴。In this study,the essential oils were extracted from both fresh and dry flowers of two cuhivars of Yunnan La-vandula spp. （ CAS07 and CAS08） using steam distillation method. The chemical constituents were analyzed using GC- MS, and their contents were determined by peak area normalization method. The results showed that the yields of fresh and dry flowers of CAS07 were 2.2% and 2.7% ,respectively,while the yields of fresh and dry flowers of CAS08 were 3.3% and 3.8% ,respectively. A significant difference （P 〈0.01 ） was observed in the yields of two cultivars but the difference was not significant （P 〉 0. 05） between the fresh and dry flowers within the same cultivar. Moreover, the prin-cipal constituents of the essential oil extracted from CAS07 were linalool （38.6%-39.2%） ,linalool acetate （21.80% - 26.71% ） and lavandulol acetate （7.69%-13.15%）. The essential oil of CAS08 extract mally included eucalyptol （49. 70%-49.80% ）, camphor （ 13.6%-14.3% ） and α-bisabolol （6.6%-7.7% ）. We found that the yields and quali-ties of oils which extracted from fresh flowers were higher than dried flowers. The results of this study can provide a theo-retical basis for Yunnan Lavandula spp. Industry policy, and a reference for the construction of the ecological park and beautiful family farms.
