摘要

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.
