摘要
目的:应用高效液相色谱法对妇科止带片中盐酸小檗碱进行含量测定。方法:选用Hypersil C18色谱柱(250mm×4.6mm,5μm),选用0.05mol/L的NaH2PO4溶液:甲醇(53:47)为流动相,检测波长为345nm,流速为1.0m l/m in,柱温:25℃。结果:盐酸小檗碱线性范围为0.07575μg^0.75750μg,r=0.9999,平均回收率为99.44%,RSD=0.92%。结论:该测定方法简便、灵敏、可行,可有效控制妇科止带片的质量。
Objective: To determine the content of berberine hydrochloride in Fukezhidai tablet with HPLC. Method: the chromatographic column of Hypersil C18 (250mm ×4.6mm,5μm) was selected, mobile phase: NaH2PO4 (0.05mol/L) : methanol(53 : 47) ; detection wavelength :345 nm ; flow rate: 1.0ml/min; temperature :25 ℃. Result: the linear range of berberine hydrechloride was 0.07575μ g ~ 0.75750μg, r = 0.9999, with the average recovery 99.44%, RSD = 0.92%. Conclusion: the method is simple, sensitive, can be used to control the quality of Fukezhidai tablet.
