【Abstract】 AIM: To investigate the factors that influence the extraction efficiency of icariin in pilot plant of continuous microwave assisted extraction and select extraction conditions. METHODS: Applying orthogonal design with three factors: permatron anodic current, solid to liquid ratio and microwave assisted irradiation time. RESULTS: The optimal strategy met the extraction conditions of permatron anodic current 0.7A , the ratio of liquid to solid 2000/15 and microwave assisted irradiation time 1.5A . In such condition the extraction efficiency of icariin was in the range of 91.59% ～ 92.65% . CONCLUSION: Microwave assisted extraction is superior to the traditional water extraction, permatron anodic current, solid to liquid ratio and microwave assisted irradiation time should be strictly controlled because they greatly influence the extraction effciency of icariin.更多还原
