萆清栓质量标准研究

摘要

Objective To establish a quality standard for Biqing Suppository. Methods Rhizoma Dioscoreae Septemlobae, Rhizoma Acori Tatarinowii, Radix Et Rhizoma Salviae Miltiorrhizae and Cortex Phellodendri Chinensis were qualitatively identified by TLC method. The content of berberine hydrochloride in Biqing Suppository was determined by HPLC method. The chromatographic column was Waters C18 (250 mm×4.6 mm, 5 μm);the mobile phase was acetonitrile∶water (0.2%phosphoric acid-0.02%three triethylamine)=25∶75;the flow rate was 1 mL/min;the detection wavelength was 265 nm. Results The spots of qualitative identification method were clear without interference. Berberine hydrochloride had good linear relationship in the range of 0.235-9.40 μg;the regression equation was Y=40 033 998.176 3X-85 021.2, r=0.999 7;the average recovery rate was 99.16%, RSD=3.45%. Conclusion The method is simple, flexible and reproducible, which can be used as the quality control standard for Biqing Suppository.%目的：建立萆清栓的质量标准。方法采用薄层色谱法对制剂中的萆薢、石菖蒲、丹参、黄柏进行定性鉴别。采用高效液相色谱法测定萆清栓中盐酸小檗碱的含量,色谱柱为Waters C18柱(250 mm×4.6 mm,5μm),以乙腈∶水(0.2%磷酸-0.02%三乙胺)＝25∶75为流动相,流速为1 mL/min,检测波长为265 nm。结果萆薢、石菖蒲、丹参、黄柏的薄层色谱斑点清晰,专属性强,阴性对照无干扰。盐酸小檗碱进样量在0.235～9.40μg范围内线性关系良好,回归方程 Y＝40033998.1763X－85021.2,r＝0.9997,平均回收率为99.16%,RSD＝3.45%。结论该方法简便、灵敏,重复性好,可作为萆清栓的质量控制标准。
