膜技术在杜仲有效成分分离纯化中的应用研究进展

Eucommia ulmoides is a traditional and precious medicinal material in China, which has the functions of anti-tumor, anti-oxidation, anti-osteoporosis, anti-inflammatory and blood pressure regulation. Its active ingredients such as chlorogenic acid and flavonoids have high medicinal value. However, the traditional Chinese medicine has complex ingredients and backward production technology. Membrane separation technology has the characteristics of high separation efficiency, low energy consumption, simple operation and no secondary pollution, and shows a good application prospect in the separation and purification of traditional Chinese medicine. As Eucommia ulmoides is a unique medicinal material in China, there are few studies on membrane separation of Eucommia ulmoides active components in the world, and the domestic research on it is still in the initial stage. It is hoped that the extraction, detection, separation and purification methods of Eucommia ulmoides active components will be reviewed to provide theoretical support for the multipolar utilization of eucommia active components. In this paper, the separation mechanism of membrane was analyzed, the application of membrane in the separation and purification of Eucommia ulmoides was reviewed, and the factors affecting the separation process were discussed. Finally, the problems of membrane materials and membrane pollution in the separation and purification of Eucommia ulmoides active components were further pointed out, and the future research of membrane technology in the development of low-cost special membrane materials and systems and membrane pollution control was prospected.
