【摘要】 目的:采用薄层扫描法测定积雪苷片中积雪草苷含量。方法:样品经适当提取后点于硅胶G薄层板上,以三氯甲烷-甲醇-水(65:35:10)下层溶液为展开剂,10%硫酸乙醇为显色剂,检测波长为λS=530nm,参比波长为λR=400nm。结果:平均加样回收率为100.7%,RSD=3.2%。结论:此方法简便、灵敏、准确,可用于该制剂的质量控制。更多还原

【Abstract】 Objective:To ddtdrmine the comtent of Asiaticoside in Jixuedaipian by TLC-scanning.Methods:The extractrion solution of the preparation was analysed on silica gel-G plate,using the CHCl3-MeOH-H2O(65:35:10)as the floor down solution developing system,10%H2SO4-EeOH Solution.as the spray veagent,then detected by dual wavelength scanning(λS=530nm,λR=400nm).Results:The average recoverys is 100.7% RSD=3.2%.Conclusions:The method is simple、sensitive、auuvate and available for quality control of Jixuedaipian.更多还原
