Abstract:
Object To study the microwave-assisted extraction process of Radix Polygoni Multiflori. Methods Using the uniform design, the optimization process of microwave-assisted extraction for total anthraquinones and 2, 3, 5, 4′- tetrahydroxystilbene-2-O-?-D-glucoside in Radix Polygoni Multiflori was gained by continuous microwave radiation. Results Some parameters, such as microwave power, radiation time, solvent concentration, solvent consumption and dipping time had interactions to the extraction of active ingredients in Radix Polygoni Multiflori. The best optimization process was obtained as following: 340 W as the microwave power, 10 min as the radiation time, 95% ethanol as the solvent, 1∶5 as the proportion of solid to liquid and 1 h as the dipping time. Conclusion The established models were proved to be reasonable by the verified experiment.
