Abstract

The invention discloses application of a membrane separation technique in the preparation of Xun Ma Zhen pills (urticaria pills). The membrane separation technique is applied to the preparation of XunMa Zhen pills; the principle of different membrane components intercepting different molecular weights is utilized; through the combination of microfiltration and ultrafiltration, Xun Ma Zhen pills extract is cleaned by membrane filtration before membrane concentration is performed; the cleaning process is optimized, and stability of a preparation is guaranteed. Compared with the traditional water-extracting alcohol-precipitating technique, the membrane separation technique herein gains references to adapt to the Xun Ma Zhen pills extract cleaning process. Experimental results show that bothpaeoniflorin and baicalin transfer rates in the Xun Ma Zhen pills made via the membrane separation technique are higher than 80%; the contents of paeoniflorin and baicalin in the Xun Ma Zhen pills arefar higher than those provided by the traditional alcohol precipitation technique; the production cost can be reduced, treatment effect can be improved, and the traditional water-extracting alcohol-precipitating technique can be replaced.

Description

technical field

[0001] The invention belongs to the field of medicine, relates to the technical field of urticarial pills, in particular to the application of a membrane separation technology in the preparation process of urticarial pills. Background technique

[0002] The chemical composition of traditional Chinese medicine is very complex, and its molecular weight ranges from tens to millions of daltons. Based on the current research results, it is believed that the main effective substances of traditional Chinese medicines and compound prescriptions are small molecular substances with a relative molecular mass of only a few hundred to a few thousand Daltons, such as alkaloids, flavonoids, saponins, organic acids, etc. The filtrate obtained by using an ultrafiltration membrane with a certain molecular weight cut-off value is different from what is commonly referred to as the "effective part" now. It is a more complex system containing many types of components, which can be...
