| Abstract: | Objective：To optimize conditions of semi-bionic extraction of Sophora flavescens. Methods：Under the unchanged con-ditions including extracting frequency, extracting course, sample concentration and detection, with the mass of oxymatrine as index, L9 （3^4 ） orthogonal design was used to investigate the effects of pH, extraction temperature, and extraction time. Results ： The first extraction pH was 2.0, the second extraction pH was 9.0, the extraction temperature was 60℃, the extraction time was 2.0 hours. Conclusion ： Optimized semi-bionic extraction methods of Sophora flavescens by orthogonal design is available. |
