贯叶金丝桃挥发油成分的GC-MS分析

GC-MS Analysis on Chemical Constituents of Volatile Oil in Hypericum perforatum

目的:分析河北产贯叶金丝桃挥发性成分。方法:采用水蒸气蒸馏法提取挥发油,通过GC-MS技术分析鉴定其化学成分。结果:从贯叶金丝桃挥发油中鉴定了58种化合物,占挥发油总量的90.0%,其中含量较高的是芳樟醇14.66%,其次为4-甲氧基丙烯基苯6.89%,苯乙醛4.66%,蘑菇醇4.41%,绿花白千层醇4.38%。结论:河北产贯叶金丝桃挥发油成分与其他地区产挥发油在成分类型和含量很大不同,影响因素主要是地域、气候环境和加工炮制工艺不同,为合理开发利用该植物资源奠定基础。

Objective： To analyze the volatile components in Hypericum perforatum from Hebei province. Method： The volatile oil was extracted by steam distillation method and its chemical constituents were analyzed and identified by gas chromatography-mass spectrometry（ GC-MS） technology. Result： The 58 compounds were isolated and identified from the volatile oil of H. perforatum,representing 90. 0% of the total amount of volatile oil. The main constituents were identified as linalool（ 14. 66%）,4-methoxypropenylbenzene（ 6. 89%）, benzeneacetaldehyde（ 4. 66%）, mushroom alcohol（ 4. 41%）, and viridiflorol（ 4. 38%）.Conclusion： The volatile oil of H. perforatum from Hebei province was significantly different from that grown in other areas,indicating that the chemical constituents could be greatly influenced by various geographical locations and environmental conditions. It provides foundation for the rational development and utilization of this plant.
