Methods Using quercetin as an index component, orthogonal design method was used to screen the optimum conditions for the microwave-assisted extraction of active ingredients in Achyranthes bidentata. The best optimized conditions for the results were: 60 mesh Achyranthes powder, microwave power 250 W, 16 times volume of water, extraction 2 times, each time 15 min. Conclusion Microwave extraction technology can quickly and efficiently extract ecdysterone from Achyranthes bidentata.
