Identification and determination of l-tetrahydropalmatine of suxiao zaoren anshen capsules

目的：对速效枣仁安神胶囊中的左旋延胡索乙素进行定性、定量测定。方法：采用薄层层析法对其进行定性鉴别，用双波长薄层扫描法测定其含量。结果：左旋延胡索乙素在０９３ ～４６５μｇ之间线性关系良好，其相关系数ｒ ＝ ０９９９６（ ｎ ＝ ３） ，平均回收率为１００１４ ％ ， Ｒ Ｓ Ｄ 为３３３ ％ 。结论：该方法快速、准确、灵敏。

OBJECTIVE:To study identification and determination of l-tetrahydropalmatine of suxiao zaoren anshen capsules.METHODS:TLC was used to identify the 1-Tetrahyeropalmatine of Suxiao Zaoren Anshen Capsules,and the 1-Tetrahydropalmatine was determined by Dual-wavlength TLC scanning.RESULTS:There was a good linearity ranging from 0.93 to 4.65μg gofl-Tetrahydropalmatine( r=0 9996,n=3) .The average recovery was 100.14% and RSD was 3.33%.CONCLUSION:This method is rapid,accurate and sensitive.
