复方黄槐片质量标准的提高
China Pharmacist(2017)
Abstract
目的:提高并完善复方黄槐片的质量标准.方法:采用TLC法对制剂中槐米、黄芩、赤芍、大黄、白茅根、鸡血藤、薏苡仁、夏枯草等8味药材进行定性鉴别;采用HPLC法测定芦丁的含量:色谱柱为DIKMA?Spursil C18柱(250 mm×4.6 mm,5μm),以甲醇-0.2%磷酸(45:55)为流动相;检测波长为350 nm;柱温为25℃;流速为1.0 ml·min-1,进样量为20μl.结果:TLC鉴别斑点清晰,阴性对照无干扰;芦丁在0.0116~0.1859 mg·ml-1的浓度范围内有良好的线性关系(r=0.9999),平均回收率为98.93%(RSD=1.14%,n=6).结论:提高后的质量标准具有操作简单、专属性强、重复性好的特点,可用于该制剂的质量控制.
