Abstract

The invention discloses a method for determining the content of schisandrin in a Yixinshu traditional Chinese medicine preparation. A schisandrin reference substance is taken as a contrast, methanol and water in a ratio of (65-75):(35-25) are taken as a mobile phase, and the content of the schisandrin in the Yixinshu traditional Chinese medicine preparation is determined with a high performance liquid chromatography. The method for determining the content of the schisandrin in the Yixinshu traditional Chinese medicine preparation with the high performance liquid chromatography is high in specificity, high in precision, good in repeatability, high in recovery rate, high in stability and accurate in measurement result, so that the medicine quality is effectively controlled, the stability of the product quality as well as the safety and effectiveness of clinical medication are guaranteed.
