粤东产重瓣臭茉莉叶挥发油化学成分的GC-MS分析

The Volatile Oil Constituents from Leaves of Clerodendrum chinense in East Guangdong

采用水蒸气蒸馏法对粤东产重瓣臭茉莉(Clerodendrum chinense(Lour.)Merr.)挥发油进行提取,并运用GC-MS对其成分进行分析和鉴定。结果分离出31个峰,确定了31种化合物,按峰面积归一化法计算各组成化合物的相对百分含量。所鉴定化合物的含量占全油的100%,其主要成份1-辛烯-3-醇(蘑菇醇)(49.50%)、(E)-3-己烯-1-醇(青叶醇)(13.39%)、芳樟醇(9.41%)、环己醇(3.37%)、3-辛醇(1.69%)、n-正戊酸-(Z)-3-己烯酯(1.42%)、1-己醇(1.38%)、糠醛(1.37%)和α-萜品烯醇(1.17%)等9种化合物占全油的81.53%。

The volatile oils were extracted from the leaves of Clerodendrum chinense （Lout.） Merr. collected in eastern Guangdong by monthod of steam-distillation, and their compositions were analyzed by GC-MS. Thirty-one compounds were identifled, accounting for 100% of the total volatile oils. The five main compounds, such as 1- octen-3 -ol （49.50%）, （E）-3-hexen-1 -ol （13.39%）, linalool （9.41% ）, cyclohexanol （3.37%）, 3-octanol （1.69%）, n- valeridc acid-cis-3-hexenyl ester （1.42%）, 1-hexanol （1.38%）, furfural （1.37%） and α-terpineol （1.17%）, accounting for 81.53% of the total volatile oils.
