摘要: 通过对决明子蒽醌类成分的几种不同提取方法的对比研究,利用分光光度法对其含量进行测定,结果表明,决明子蒽醌类成分浓度在0.865~25.937mg/L范围内与吸光度呈良好的线性关系(r=0.9998),平均回收率为101.7%,RSD为0.35%,建立了一个简便、准确的蒽醌类成分含量的测定方法。

Abstract:  To contrast four extract methods of anthraquinones component of Cassia tora L, anthraquinones were determined by using UV spectrophotometry method. Results showed that anthraqiunones component have a good linearily in the concentration range of 0.865~25.937 mg/L (r=0.9998). The average recovery is 101.7% with RSD of 0.35%, and an easily, accurate anthraquinones component content determination method has been established.

Key words: Cassia tora L, anthraquinones, UV spectrophotometry
