目的:为了更好的控制补脾益肠丸质量,对补脾益肠丸中苦杏仁苷的含量进行测定。方法:采用Zorbax SB-C18柱(250 mm×4.6 mm,5μm);流动相:乙腈-0.1%磷酸溶液(8∶92);检测波长为210 nm;柱温35℃。结果:苦杏仁苷在10.25~512.5μg范围内线性关系良好,r=0.9999,平均回收率98.91%,RSD=0.48%。结论:此方法操作简便、准确、重现性好,可有效的控制补脾益肠丸的质量。
Objective: In order to better control the quality of the Spleen Yixie Pills, determination of the content of amygdalin in the spleen and intestine pills. Methods: A Zorbax SB-C18 column (250 mm × 4.6 mm, 5 μm) was used. The mobile phase was acetonitrile-0.1% phosphoric acid solution (8:92). The detection wavelength was 210 nm. Results: The amygdalin had good linearity in the range of 10.25-512.5 μg with r = 0.9999, the average recovery was 98.91% and the RSD was 0.48%. Conclusion: This method is simple, accurate, reproducible, and can effectively control the quality of Bupi Yichang Pills.
