摘要:

采用水蒸汽蒸馏法提取单性木兰种皮的挥发组分，用GC MS分别定性定量分析了提取的油层精油和溶解在水中的化学成分。结果表明，挥发组分的提取率为4.2%，其中，油层精油得率为3.5%，主要成分中萜烯类化合物多，含量高，其中罗勒烯37.3%、D 苧烯9.03%、对伞花烯8.10%、β 月桂烯7.79%、β 反罗勒烯4.08%、对孟 1 烯4.00%、α 侧柏烯3.11%；水层乙醚萃取率0.7%，其中α 松油醇6.13%、对伞花烃557%、D 苧烯5.33%、6 甲基 3，5 庚二烯 2 酮4.44%、4 甲基 4 戊烯 2 酮4.16%。

Abstract:

The volatile constituents of testa of Kmeria septentrionalis were extracted by the steam distillation. The chemical constituents of essential oil and compounds of dissolution in water have been analyzed by GC MS. The results show that extractive yield of volatile chemicals is 4.2%(essential oil 3.5%，extractive substance from water 07%). The terpene compounds are rich and high content in the major constituents of essential oil. The compounds of essential oil are α cimene(37.30%)，D Limonene(9.03%)，p Cymene(8.10%)，β Myrcene(7.79%)，β trans Ocimene(4.08%)，p Menth 1 ene(4.00%)，and α Thujene(3.11%). The major constituents in dissolution of water with ether extraction are α Terpineol(6.13%)，p Cymene(5.57%)，D Limonene(5.33%)，6 Methyl 3，5 heptadiene 2 one(4.44%)，4 Methyl 4 penten 2 one(4.16%).
