摘要
以乙醇提取花生壳中的木犀草素,考察了乙醇浓度、浸提时间、料液比和温度等对提取率的影响。结果表明,乙醇浓度75%,浸提时间2 h,料液比1∶25,温度70℃为最佳提取条件。运用紫外可见分光光度法对最佳提取条件下提取的花生壳中木犀草素含量进行测定,测得木犀草素含量为0.013 mg/g。
Extract Luteolin from peanut shell by ethanol,the influence of ethanol concentration,extraction time,solid-liquid ratio and temperature to extraction rate were studied.The results showed that the optimum extraction conditions was ethanol concentration 75%,extraction time 2 h,ratio of solid to liquid 1∶ 25,temperature 70 ℃.Application of UV was used to determine the content of Luteolin from peanut shell extraction conditions for extraction of visible spectrophotometry,measured the Luteolin content was 0.013 mg/g.
