摘要 利用微波辅助提取法 (MAE)提取刺五加中的黄酮类化合物 ,通过正交实验 ,考察了微波提取条件(包括溶剂、微波辐射时间、提取压力和料液比 )对刺五加中总黄酮提取率的影响 ,结果表明 :溶剂为 5 0 %乙醇 ,提取压力为 70 0kPa ,提取时间为 10min ,料液比为 1∶2 0时 ,提取率最佳。与索氏提取法相比较 ,提取率可提高 4 0 %。 Flavonoids from Acanthopanax Senticosus Harms were extracted by means of a microwave-assisted extraction (MAE) technique. The influence of some operation conditions, such as ethanol content, microwave irradiation time, processing pressure and the ratio of sample weight to solvent volume, on the extraction yield of those compounds has been studied by using orthogonal test and optimization based on multivariate statistics. The experimental results show that the highest extraction yield can be obtained when extraction solvent is 50% ethanl, processing pressure is 700 kPa, microwave irradiation time is 10 minutes and the ratio of sample weight to solvent volume is 1∶[KG-3/5]20. Under the optimum conditions of MAE, there is a 40% increase of the extraction yield of flavonoids as compared with Soxhelt extraction.
