摘　　要：目的:考察五味子藤茎中木脂素含量在12个月内的变化规律,为确定适宜的采收期、合理开发利用其植物资源提供科学依据。方法:以五味子醇甲、五味子甲素、五味子乙素为对照品,采用反相HPLC测定。结果:不同月份五味子藤茎中3种木脂素成分的含量各不相同:五味子醇甲含量在12月份最高,为2.3 mg.g-1生药;4月份最低,为1.4 mg.g-1生药。五味子甲素在11月份含量最高,为0.8 mg.g-1生药;3月份最低,为0.4 mg.g-1生药。五味子乙素在1月份含量最高,为3.0mg.g-1生药;4月份最低,为1.1 mg.g-1生药。结论:以秋、冬季采收为佳。Objective: To determine lignan content in the vine stem of Schisandra chinensis during 12 months and provide the scientific basis for the development and utilization of the resources.Method: Analysis was carried out on an Eclipse XDB C18 column eluted with a mixture of methanol-acetonitrile-water(43∶28∶29) as the mobile phase.The flowrate was 1.0 mL·min-1,and the detection wavelength was set at 250 nm.Schisandrin,deoxyschizandrin and schisandrin B were used as reference substance,and the external standard m...
