摘要
分光光度法测定清宁丸中总蒽醌含量，以大黄素为参比物，０．５％醋酸镁甲醇液为显色剂，测定波长为５１３ｎｍ；线性范围：０．０３１４～０．２１８８ｍｇ／ｍｌ（ｒ＝０．９９９８），平均回收率９９．６７％（ＣＶ％＝０．９５，ｎ＝６）；并对不同的提取方法进行了比较．为清宁丸质量考核提供了一个准确、可行和实用的方法．
An accurate method for measuring anthraquinone in Qingningwan was developed byspectrometry with emodinoas an external standard. The wavelength was 513 nm. Calibrationcurye was linear in the range of 0. 0314 - 0.2188 mg/ml (r = 0.9998) and average recovery was99.67%. Coefficient of variation was 0.95% (n = 6). The anthraquinone contents in several Qing-ningwan samples were determined.
