粤东产重瓣臭茉莉挥发油化学成分的GC-MS分析

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

摘要:

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a-萜品烯醇(1.17%)等9种化合物占全油的81.53%。

Abstract:

The volatile oils were extracted from the leaves of Clerodendrum chinense (Lour.) Merr. collected in eastern Guangdong by monthod of steam-distillation, and their compositions were analyzed by GC-MS. Thirty-one compounds were identified, 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 a-terpineol (1.17%), accounting for 81.53% of the total volatile oils.
