Study on Flash-type Extraction Process for Total Flavonoids and Icariin from Herba Epimedii
Objective: To study and optimize the extraction and preparation technics of icariin and total flavonoids by orthogonal design. Method: The best conditions of extracting icariin and total flavonoids from Herba Epimed by flash-type extraction were screened by using method of orthogonal design and selecting the amount of icariin and total flavonoids as index. Result: The effect influencing factors of flash-type extraction were as follows: extraction times>duration of extraction>ratio of solid to liquid>concentration of ethanol. The optimum extraction condition obtained was: 10 minutes and 3 times
ratio of solid to liquid 1 ∶25
50% ethanol. Conclusion: Flash-type extraction was found to be an efficient and rapid method for extracting total flavonoids and icariin from Herba Epimedii.
