摘要:
目的 建立HPLC法测定养血安神丸中2,3,5,4'-四羟基二苯乙烯-2-O-β-D-葡萄糖苷的含量。 方法 用Waters C18(4.6 mm×250 mm,5 μm)色谱柱,流动相:乙腈-水(20:80),流速:1.00 ml/min,检测波长:320 nm。 结果 2,3,5,4'-四羟基二苯乙烯-2-O-β-D-葡萄糖苷在0.086 7~1.083 5 μg范围内与峰面积线性关系好,r=0.999 8,平均回收率为99.2%,RSD为1.1%(n=9)。 结论 本法测定简便,结果准确,灵敏度高,重复性好,可用于养血安神丸的质量控制。
Abstract:
Objective To establish a HPLC method for determination of stilbene glucoside in Yangxueanshen Pills. Methods The Waters C18 column (4.6 mm×250 mm, 5 μm) was used. The mobile phase was acetonitrile-water (20:80).The flow rate was 1.0 ml/min.The detection wavelength was 320 nm. Results The linear range was 0.086 7 μg~1.083 5 μg(r=0.999 8). The average recovery was 99.2% with RSD=1.1% (n=9). Conclusion The determination method was simple, accurate, sensitive and reproducible which could be used for quality control of Yangxueanshen Pills.
