摘要
以西兰花种子为原料,提取其中的萝卜硫素,考察了水解pH值、水解时间、萃取溶剂对提取率的影响。结果表明,在水解pH值为4.0、水解时间为12h、萃取溶剂为乙酸乙酯时,萝卜硫素提取率达3.5%,提取纯度超过95%。
Extraction of sulforaphane from broccoli seeds was studied in this paper.The effects of hydrolysis pH value,hydrolysis time,extraction solvent on extraction rate of sulforaphane were investigated.Results showed that when hydrolysis pH value was 4.0,hydrolysis time was 12 h,extraction solvent was ethyl acetate,the extraction rate of sulforaphane reached 3.5% and the purity was up to 95%.
