仙灵二至颗粒的质量标准研究

摘要

Objective To establish the quality standard for Xianling Erzhi Granules .Methods Eclipta prostrate L .and Anemarrhe-na asphodeloides Bge .were identified by TLC ;icraiin was determined by HPLC .Results Eclipta prostrate L .and Anemarrhena asphodeloides Bge .could be detected by TLC ;The linear range of icraiin was good in the range of 1 .3-3 .8 μg ,r=0 .999 9 .The average recovery of icraiin was 99 .4% (RSD=1 .1% ) .Conclusion The established methods are stable ,accurate and good repro-duceable .This study provides a method for the quality control of Xianling Erzhi Granules .%目的：建立仙灵二至颗粒的质量标准。方法采用TLC法对仙灵二至颗粒中墨旱莲和知母进行定性鉴别；应用HPLC法对仙灵二至颗粒中的淫羊藿苷进行含量测定。结果墨旱莲和知母的薄层鉴别方法专属性强，简单可行。淫羊藿苷进样量在1．3～3．8μg范围内呈良好的线性关系，r＝0．9999；平均回收率为99．4％（RSD＝1．1％）。结论该方法稳定、准确、重复性好，可用于仙灵二至颗粒的质量控制。
