| 摘 要： | 通过水蒸气蒸馏法制备海金沙挥发油,用GC/MS分析了挥发油乙醚萃取物的化学成分,构建了海金沙的气相色谱指纹图谱,并进行了方法学考察。指纹图谱由14个特征峰构成,不同产地样品的图谱有一定差异;指纹图谱相对保留时间的精密度、稳定性和重现性的RSD分别在1.8%,1.76%和2.45%以下。挥发油用GC/MS共检出20个化学成分,主要成分是α-油酸单甘油酯和油酸二羟基乙酯,相对含量分别为47.82%和42.77%。

| Abstract: | The volatile oil from Lygodium japonicum was prepared by water vapor distillation method and its chemistry composition was analysed by GC/MS.The fingerprint of the volatile oil was established by gas chromatography and its methodology was investigated.The fingerprint is consist of fourteen characteristic peaks and fingerprint of sample from different producing area was different.RSD of the precision,stability and repeatability of fingerprint's relative retention times are 1.8%,1.76% and 2.45%,respectively.Twenty chemical substances in volatile oil was analysed by GC-MS,main constituent is α-monoolein and oleic acid 2-hydroxyethyl ester,and relative content is 47.82% and 42.77%,respectively. |
