摘要
用色谱、色谱-质谱联用、红外光谱和其他化学方法鉴定了樟精油中的34个成分。通过164株樟不同部位的363个精油样品的分析,观察到不同树龄的植株及不同部位精油成分的差异。叶部精油具有显著的特征。按照叶油的主成分可将樟划分为五个化学类型(生理类型):樟脑型、芳樟醇型、桉油素型、龙脑型和异橙花叔醇型。
Cinnamomum camphora is one of the important economic trees in China.The essential oil is obtained from its leaves,branches,trunks and roots.Total 164 trees were selected in Jiangxi province.Different organs of each tree were cellected and steam-distilled 363 essential oil samples were analyzed and quantitated for their constituents by gas chromato- graphy.By means of GC,GC/MS/DS,IR and other chemical methods,34 chemical com- pounds were identified.Cinnamomum camphora could be divided as following chemical types(physiololgical-types)by the major compounds of their leaf oils:camphor-type; linalool-type;cineol-type;isonerolidol-type and borneol-type.
