摘要
通过薄层层析从锁阳中提取分离出熊果酸，并用紫外分光光度法测定其含量为０７８％。实验平均回收率为９７４％，ＲＳＤ＝０．４５％（ｎ＝４）。
Ursolic acid was isolated form Herba Cynomorii by thin layer chromatography and was quantitatively determined by ultraviolet spectrophotometry.The results indicate that the content of ursolic acid is 0.78%.The average recovery rate of ursolic acid is 97.4%,RSD=0.45%(n=4).
