| Abstract: | OBJECTIVE：To optimize the extracting process of the total flavonoids from Herba Epimedii.METHODS： The extract technology of the total flavonoids from Herba Epimedii was optimized by orthogonal experiment with the yield of total flavonoids from Herba Epimedii as index and with the extraction temperature, extraction time, the ratio of solid to liquid and the concentration of ethanol as factors.RESULTS： The optimum extracting conditions for the total flavonoids from Herba Epimedii were as follows： the reflux extraction was conducted twice （1 hour/time） at 80℃ with 60% ethanol as solvent, and the ratio of solid to solution was 1 ： 10.CONCLUSION： The optimum extracting technology is simple and reasonable, and it serves as a good reference for the extracting process of the total flavonoids from Herba Epimedii. |
