蓝玉簪颗粒的质量标准提高
China Pharmacist(2019)
Abstract
目的:建立蓝玉簪颗粒的质量提高标准.方法:采用TLC法定性鉴别蓝玉簪龙胆和三七总皂苷;采用HPLC法定量测定龙胆苦苷的含量.色谱柱为Promosil C18柱(250 mm×4.6 mm,5μm),以甲醇-水(27∶73)为流动相,检测波长为270 nm,流速为1.0 ml· min-1,进样量为10 μl,柱温25℃.结果:薄层鉴别斑点清晰,阴性对照无干扰;龙胆苦苷含量在25.00 ~1 000.00 μg·ml-1之间线性良好(r=0.999 9),平均回收率为98.24%,RSD为3.04%(n=6).结论:本方法结果可靠,操作简便,可用于蓝玉簪颗粒的质量控制.
