微波辅助提取洋葱籽中皂苷类成分工艺研究

摘要

用微波辅助甲醇提取洋葱籽中的皂苷类成分,考察甲醇浓度、微波时间、微波功率、料液比对皂苷类成分得率的影响.结果表明,最佳提取工艺条件为:甲醇浓度100%,料液比1:25g/mL,微波功率400W,微波时间25min,总皂苷提取率为6.87%.%Extracting saponin from onion seed by microwave with methanol.The influence of methanol concentration,microwave time,microwave power and ratio of material to liquid on saponin yield were in-vestigated.The result showed that the optimum process condition is methanol concentration 100%,ratio of material to liquid 1:25 g/mL,microwave frequency 400 W,microwave time 25 min,the yield of saponin is 6.87%.
