摘　　要：为了解不同株龄薰衣草花生物学性状、精油主要化学成分及含量差异,以昆明薰衣草CAS08(Lavandula angustifolia Mill.×Lavandula latifolia Medik.)为试材,对不同株龄(一年生、两年生和三年生)薰衣草的花枝、精油提取率和精油成分变化进行了研究。结果显示,不同株龄薰衣草的单支花生物学性状差异显著(P<0.05);薰衣草花精油的提取率在不同株龄间有差异,分别为一年生熏衣草花精油提取率3.40%、两年生2.37%和三年生3.60%;薰衣草CAS08花精油的主要成分有桉叶油醇、芳樟醇、樟脑和红没药醇,株龄对精油中各化学成分的相对含量有影响。本研究结果可为云南薰衣草产业化发展及持续开发利用提供科学依据。We investigated changes in botanical characteristics and essential oils from the flowers of lavandin at different plant ages. This research focused on changes in the flowers and both content and composition of essential oil extracted from lavandin CAS08（ Lavandula angustifolia Mill. × Lavandula latifolia Medik.） of different aged plants collected from Yunnan,China. The results showed significant differences（ P〈0. 05） in botanical characteristics among the different aged flowers of lavandin CAS08. Moreover,differences in essential oil content also occurred in annual,biennial and three-year-old plants（ 3. 40%,2. 37% and3. 60% respectively）. The major components of the essential oil were eucalyptol,linalool,camphor and α-bisabolol. The age of plants had an effect on the relative content of chemical compositions. The findings of this study provide a reference for the industrialization of lavandin and sustainable extraction of oil content from plants grown in Yunnan.
