Abstract
[Objective] To optimize the optimal microwave extraction process for hyperoside from Hypericum perforatum L.[Method] With the extraction rate of hyperoside as the evaluation index,effects of factors were studied in orthogonal test,such as radiation temperature,microwave power,microwave radiation time and solid-liquid ratio.[Result] The optimal extraction technology for microwave extraction process of hyperoside from H.perforatum were established,which was 50 ℃ radiation temperature,500 W microwave power,9 min radiation time,and 1:20 solid-liquid ratio.[Conclusion] This extraction technology was reliable and stable,and was suitable for the extraction of hyperoside from H.perforatum.
