碱法提取花生红衣中白藜芦醇的研究

Study on resveratrol from red skin of peanut by alkaline extraction method

研究了碱法从花生红衣中提取白藜芦醇的工艺。对pH,温度,提取时间和提取次数四个因素分别进行了单因素和正交实验,从而得到最佳的提取工艺条件,即:pH10.0,温度为40℃,提取时间2h,提取次数4次。实验结果表明,花生红衣中白藜芦醇的得率可达0.196%。

Research has been carried out on the alkaline extraction of resveratrol from the red skin of peanuts.The pH value,extraction temperature, extraction time and extraction times were studied respectively by single factor and orthogonal experiment.The result showed the optimum conditions were as follows： pH value 10.0, extraction temperature 40℃, extraction time 2h and the number of extraction times 4, under this condition ,the extraction yield of resveratrol could reach as high as 0.196%.
