中药中有效成分是其治疗疾病的物质基础,但是传统的提取分离技术已经满足不了现代医学发展的需要。近年来,国内相关生产企业为了能使中药产品生产和销售在国际市场占有更多的份额,研究开发出多种先进的提取分离技术。1中药提取的新方法1.1超临界流体萃取与常规有机溶剂相比,超临界流体有着特殊的密度、粘度和扩散系数,这使得其在提取中草药有效成分时,有着更高的溶解能力和更好的流动性,可以代替易挥发、有毒、易燃等传统
The active ingredients in traditional Chinese medicine is the material basis for its treatment of diseases, but the traditional extraction and separation technology can not meet the needs of the development of modern medicine. In recent years, relevant domestic manufacturing enterprises have researched and developed a variety of advanced extraction and separation technologies in order to make the production and sales of Chinese medicine products occupy more shares in the international market. A new method of extraction of Chinese medicine 1.1 Supercritical fluid extraction Compared with conventional organic solvents, supercritical fluid has a special density, viscosity and diffusion coefficient, which makes it in the extraction of active ingredients of Chinese herbal medicine has a higher solubility and better Of the liquidity, can replace the volatile, toxic, flammable and other traditions
