| Abstract: | Objective: To study the optimum extraction technology of active components from Astragalus membranaceus.Methods: ASP and AS were obtained with the methods of ethanol extraction first, and the water extraction second, then the optimum times of ethanol extraction were determined.Results: The amount of alcohol and extraction time had significant influence on ASP and AS extraction. Conclusion: Using 95% alcohol to extract AS and then using water to extract ASP is optimum for the full utilization of Astragalus membranaceus. |
