介绍了分子蒸馏基本原理与技术特点,是一种新型的液-液分离纯化技术,具有蒸馏温度低、受热时间短、分离程度高等优点。叙述了分子蒸馏在维生素、不饱和脂肪酸、挥发油等中药及合成药物粗产物有效成分的分离纯化方面的应用及进展。认为我国在这方面的研究应用起步相对晚,需要进一步探索分离与纯化的最佳工艺条件。
The basic principle and technical characteristics of molecular distillation are introduced. It is a new liquid - liquid separation and purification technology with the advantages of low distillation temperature, short heating time and high degree of separation. Describes the application and progress of molecular distillation in the separation and purification of the active ingredients of crude drugs such as vitamins, unsaturated fatty acids, volatile oil and other traditional Chinese medicines and synthetic drugs. That China’s research and application in this area started relatively late, the need to further explore the best separation and purification process conditions.
