西药制取过程十分复杂,需要应用多种分离纯化技术,不同的分离纯化技术,其应用效果不同,其应用的领域也有很大差异。传统的分离纯化技术有比较多的劣势,比如成本高、提取率低等,为此西药制取研究人员研究了很多新型的技术,比如扩张灌注层析技术、径向膜层析技术以及灌注层析技术等,这些技术的应用是我国西药制取的进步,本文主要介绍了四种提取分离纯化技术,仅供参考借鉴。
Western medicine preparation process is very complicated, the need to apply a variety of separation and purification techniques, different separation and purification techniques, the application of different results, its application areas are also very different. Traditional separation and purification techniques have more disadvantages, such as high cost, low extraction rate, for which Western medicine researchers studied many new technologies, such as the expansion of perfusion chromatography, radial membrane chromatography and perfusion technology Analysis of technology, the application of these technologies is the progress made by Western medicine in China, this paper introduces four extraction and purification techniques, for reference purposes only.
