靛玉红是中药青黛中治疗慢性粒细胞白血病的有效成分,目前常用半合成品。靛玉红片中靛玉红含量的测定方法有多种,其中比色法操作较繁,不能消除靛蓝的干扰。解联立方程法必须已知或用实验测定。双波长薄层扫描法操作不够迅速。后两种方法回收率均偏低。本文报道的方法简便,测定迅速,准确度较高。 Indirubin is an active ingredient in the treatment of chronic myelogenous leukemia in Chinese medicine Qingyezhong. It is currently used as a semi-synthetic product. There are many methods for determining the content of indirubin in the indigo red tablets. Among them, the colorimetric method is more complicated and can not eliminate the indigo interference. The simultaneous equation method must be known or determined experimentally. Double-wavelength thin-layer scanning is not fast enough. The recovery of the latter two methods is low. The method reported in this paper is simple, rapid and accurate.
