Abstract
本实验建立了天泰牌改善睡眠软胶囊的质量标准。薄层色谱法定性鉴别莲心碱;高效液相色谱法测定五味子醇甲、五味子甲素和五味子乙素含量。选择Diamonsil C18色谱柱(150mm ×4.6mm ,5μm ),以甲醇-水溶液(60∶40)为流动相,梯度洗脱,检测波长254nm ,流速1.0mL/min ,柱温25℃。结果,莲心碱的斑点清晰,分离度好;五味子醇甲在质量浓度24.88μg/mL~111.96μg/mL、五味子甲素在质量浓度22.46μg/mL~101.07μg/mL、五味子乙素在质量浓度20.42μg/mL~91.89μg/mL范围内呈良好的线性关系,平均回收率分别为99.65%、99.45%、99.58%。所用方法简便可行,分离度好、重现性好,可作为天泰牌改善睡眠软胶囊的质量控制方法。
