摘要
以降香黄檀可再生资源——叶子为原料,利用离子液体微波辅助提取技术对鹰嘴豆芽素A和染料木素进行提取。通过单因素实验,3因素3水平的BBD(Box-Behnken design)实验,对提取条件进行优化,确定了离子液体微波辅助提取降香檀叶中鹰嘴豆芽素A(biochanin A)和染料木素(genistein)的最佳提取工艺条件:1.00 mol·L^(-1)[C_4MIM]Br,提取温度为56℃,液固比18:1,提取时间为11 min,提取功率300 W。在最佳提取条件下,鹰嘴豆芽素A和染料木素平均提取率分别可达1.598和0.939 mg·g^(-1)。
In the present research, single-factor experiments and a three-variable, three-level Box-Behnken design were performed to study the ionic liquids-based microwave-assisted extraction of biochanin A and genistein from D. odorifera T. Chen leaves. The optimum parameters were： 1.00 mol . L-l[ C4MIM] Br, extraction temperature 56℃, liquid/solid ratio 18：1 mL . g-I, extraction time 11 min, irradiation power 300 W. Under the optimal conditions, the average extraction yields of biochanin A and genistein were 1. 598 and O. 939 mg g- 1, respectively.
