【摘要】 目的 分析并区分重楼中薯蓣皂苷元类化合物与偏诺皂苷元类化合物。方法 利用高效液相色谱／大气压化学电离质谱联用技术,在正离子模式下,利用多离子监测法对重楼进行特征离子的同时监测。结果有效地将重楼中的薯蓣皂苷元类化合物与偏诺皂苷元类化合物区分开来。结论 建立了一种简单、快速、准确的用于区分不同苷元类型的皂苷类化合物的联用方法。更多还原

【Abstract】 Objective To analyze and discriminate steroid saponins in Paris Polyphylla. Methods By means of HPLC-APCI/MS, In positive mode , the characteristically fragment ions of diosgenin and pennogenin saponins were monitored simultaneously with multiple ions monitor mode(MIM) in Paris Polyphylla. Results Diosgenin and pennogenin were successfully discriminated. Conclusion This method is a simple, fast and accurate method for discriminating different steroid saponins.更多还原
