【摘要】 优选资木瓜中皂苷的提取工艺。以木瓜皂苷的提取总量为考察指标,采取正交试验法考察乙醇浓度、溶媒用量、提取时间、提取次数4个因素,每个因素设置3个水平。最佳提取工艺为乙醇浓度70%、溶媒容量10倍、提取时间1h、提取3次,木瓜皂苷得率为1.7%。对木瓜皂苷得率有明显影响的是提取次数及乙醇浓度。更多还原

【Abstract】 Optimize extraction technology of saponin from chaenomeles.Use orthogonal design L(93)4on four factors including alcohol level,alcohol volume,extraction time and extraction frequency and take the saponin rate as the index.The best technology was at alcohol level 70 %,10-fold alcohol volum,extracting 1 h and 3 times,saponin yield from chaenomeles was 1.7 %;the main factor influenceing saponin yield was alcohol level and extraction frequency.更多还原
