In order to evaluate the performances of the optimal extraction method,six extraction methods including accelerated solvent extraction,SFE-CO_2 extraction,reflux extraction,Microwave extraction,Ultrasonic extraction and Soaking extraction were used to extract bioactive compounds from S. moellendorfii. HPLC method was attempted for quantitative analysis and comparison among different extracts was made by determining the content of amentoflavone. Furthermore,antioxidative activity of different extracts were d...
