摘要
以肽得率为判优指标,研究了添加前处理措施及低浓度碱液为提取液的灵芝多糖肽提取工艺。结果表明:石油醚脱脂预处理后,约能提高得率36.4%,灵芝多糖肽的最佳提取工艺条件为:温度100℃,料液比1:30,提取液为0.5%碳酸钠溶液,提取时间为2.0h,提取率为2.07%。这4个影响因素按从主到次的顺序排列依次是:温度>料液比>碱性盐溶液浓度>提取时间。
Taking peptide yield as index,the extraction process of Ganoderma lucidum polysaccharides peptide with the extraction adding pre-treatment measures and the low concentration of alkali was studied.The results showed that:after petroleum ether degreasing pretreatment,polysaccharide peptide yield could be increased 36.4%,the best extraction conditions of Ganoderma lucidum polysaccharides peptide were:temperature 100℃,liquid ratio 1:30,0.5%sodium carbonate solution,extraction time 2 h,extraction rate 2.07%.The order from the primary to the inferior by the order was:temperatureliquid ratioalkaline salt concentration extraction time.
