| Abstract: | To optimize the extraction procedure for flavonoid glycosides from piper wallichii(Miq.) Hand.-Mazz by ethanol.The effect of solid-liquid ratio,extraction temperature,time,volume fraction of ethanol on extraction yield.The result showed that the optimum extraction condition was as follows:volume fraction is 50%,solid-liquid ratio is 1 ∶40,the extraction time is 2.5 h,the temperature is 90 ℃.The extraction ratio of flavonoid glycosides can be up to 4.2% under this condition. |
