| Abstract: | Objective] The aim was to optimize the extraction conditions of resveratrol from peanut.Method] The resveratrol was extracted from the peanut powder,and the effects of ethanol concentration,extraction temperature,extraction time and solid-liquid ratio were studied with single factor experiment,and the extraction conditions by organic solvents reflux were optimized by orthogonal experiment.Result] The influential degree of each factor decreased in the order of ethanol concentration>extraction temperature>extraction time>solid-liquid ratio,and the best extraction conditions were 40% ethanol concentration,1∶25(g∶ml) solid-liquid ratio,75 ℃ of extraction temperature and 150 min extraction time,under these conditions,the yield of resveratrol was 0.46%.Conclusion] The method selects the optimal extraction conditions of resveratrol from peanut,and it is accurate and reliable. |
