摘要

目的:确立泽泻中alismol的测定方法。方法:对泽泻中的主成分alismol进行分离鉴定以制备对照品,将泽泻粉末经硅胶柱预处理,洗脱液再薄层层析,进行光密度扫描测定。结果:样品alismol含量为0.021%,RSD=4.1%,在1.5 h内稳定性,回收率103. 8%。结论:本方法灵敏、专属,重现性好,简便易行。

Abstract

OBJECTIVE: To stablish TLC-densitometry of alismol in Rhizoma Alismatis. METHODS: The samples were extracted by CC(hexane - CH2 Cl2 ,1:1)method and subjected to TLC-densitometry ( coloured by silimtungstic acid). RESULTS: The alismol content in Rhizoma Alismatis was 0.021%and RSD was 4.1%.CONCLUSION Alismol was efficiently quantitated by TLC-densitometry.
