目的　介绍提携剂在中草药超临界CO2 流体萃取中的研究概况。方法　根据近年来的文献 ,对超临界CO2 流体纯气体溶剂中加入提携剂 ,使用混合溶剂提取中草药中分子量较大或极性较强的物质的研究概况进行了综述。结果与结论　提携剂的加入对中草药中分子量较大或极性较强的物质具有较好的提取效果。该技术在中草药CO2 流体萃取技术中具有广阔的研究和发展前景 OBJECTIVE To introduce the research progress of the use of co-agents in supercritical CO2 fluid extraction of Chinese herbal medicines. Methods According to the recent literature, the review of the research status of the use of mixed solvents to extract the substances with higher molecular weight or higher polarity in the pure gas solvent of supercritical CO2 fluids was reviewed. Results and conclusions The addition of the carrier-inhibiting agent has a better extraction effect on the relatively large molecular weight or more polar substances in the Chinese herbal medicine. This technology has broad research and development prospects in Chinese herbal medicine CO2 fluid extraction technology
