Determination of Baicalin in Xiaoer Feire Kechuan Mixture by Dual-wavelength Spectrophotometry

采用双波长分光光度法测定中药复方制剂小儿肺热咳喘口服液中黄芩的主要成分黄芩甙的含量。样品可不经分离,用双波长法消除共存的干扰,直接进行测定。同时使用UV-3000和751型分光光度计,所得结果基本一致。

A method for the determination of baicalin in traditional Chinese medicine Xiaoer Feire Kechuan Mixture with dual-wavelength spectrophotometry is described. The interference of coexisting ingredients may be eliminated without separation of the samples. Both 751 and UV-3000 spectrophotometers were used.
