摘要
以离子液体作为微波吸收介质建立了离子液体-非极性溶剂微波提取法,对人参中的化学成分进行了提取,并将该法与固体微波吸收介质-非极性溶剂微波提取法、极性溶剂微波提取法以及混合溶剂微波提取法进行了对比.结果表明,极性溶剂提取的主要化学成分为极性化合物,而固体微波吸收介质-非极性溶剂微波提取法与离子液体-非极性溶剂微波提取法相比,提取所得的化学成分并无明显差别,说明离子液体是一种较好的微波吸收介质和能量传递材料.所建立的方法具有提取时间短、操作简单及绿色环保等优点,且对后期分析无明显影响,是快速提取化学成分的理想方法.
The ionic liquids（IL） was used as the microwave absorption medium and an ionic liquid-non polar solvent microwave extraction（ILNPSME） method was developed.The proposed method was applied to the extraction of the chemical constituents from the root of Panax ginseng C.M.Mey.The ILNPSME method was compared with solid microwave absorption medium-non polar solvent microwave extraction（SMMNPSME）,polar solvent microwave extraction（PSME） and combined solvent microwave extraction（CSME） methods.PSME method is suitable to the extraction of polar constituents.The main chemical constituents obtained by SMMNPSME and ILNPSME methods are similar,which indicate that the IL can act as a microwave absorption medium and energy translation material.The proposed method has many advantages,such as short extraction time,simple operation and the use of green solvent,and is a suitable method to extract the chemical constituents from plant meterials.
