摘　　要：目的 :测定不同来源竹叶中荭草苷、异荭草苷和异牡荆苷的含量。方法 :用HPLC法测定 ,以MeOH H2 O HAc(35∶6 5∶1)为流动相 ,340nm为检测波长。结果 :不同来源最高含量为 0 .89% ,最低含量为 0 .0 7%。结论 :该法简单、快速、准确。AIM: To determine the contents of orientin,isoorientin,isovitexin in Bamboo Leaf from different sources. METHODS : Orientin,isoorientin,isovitexin were determined by HPLC. The mobile phase was MeOH-H_2O-HAc (35∶65∶1). The detective wavelength was at 340nm. RESULTS : The highest content of three favonoids was 0.89% and the lowest content was 0.07% from different sources. CONCLUSION : This method is simple,quick and accurate for determination of the three favonoids in Bamboo Leaf from different sources.
