[Objective]The aim was to find the best process for the extraction of flavonoids from Momordica charantia.[Method] The effects of different conditions including ethanol concentration,extraction time,extraction temperature,extraction power and solid liquid ratio on extraction efficiency were studied using single facter experiment and orthogonal experiment.[Result] The optimal extracting conditions were as follows:90%ethanol,extraction time of 20 min,1∶60 g/ml solid liquid ratio,extraction temperature of 70 ℃...
