Abstract

The invention discloses a content measurement method of abrus herb capsules. In the method, a high performance liquid chromatography-ultraviolet (HPLC-UV) method is used for measuring the contents of apigenin-6,8-di-C-glucoside, apigenin-6-C-arabinose-8-C-glucoside and apigenin-6-C-glucose-8-C-arabinoside in abrus mollis hance (monarch drug in a prescription) in the abrus herb capsules under the same chromatographic condition. The method comprises the following steps: preparing a test sample solution; preparing a control sample solution; and measuring by gradient elution. The method has the advantages of strong specificity and better accuracy, precision and reproducibility, is simple and easy to operate, and has important significance for further perfecting the quality standards of the abrus herb capsules.
