| Abstract: | Study on the influence of the extraction condition of procyanidin from purple sweetpotato by microwave-assisted,such as the concentration of ethanol,the ratio of sample to extractant and the time of microwave processing.As a result,the optimum extracting condition was that ethanol and hydrochloric acid as the solvent,50% ethanol as the extracting reagent,the ratio of sample to extractant is 1:70,exracting 60 s.In this condition,procyanidin extracted reach 1.98 mg/g. |
