| Abstract: | Objective： To optimize the ultrasound extraction process of Herba Epimedii. Methods： The optimum extraction conditions were investigated by orthogonal design and with Icariin as the content index by HLPC. Results： The factors influencing extraction efficiency were as follows： A〉B〉D〉C （A： the concentration of ethanol. B： material ratio. C： temperature of extraction. D： times of extraction）. The optimum extraction condition obtained was： Ultrasound 300W, 60 percent ethanol , Material ratio 25：1. Temperature of extraction 50℃ Times of extraction 60min. The content of Icariin was 94.88% with a good reproducibility. Conclusion： The optimized process is stable and high efficient. |
