With the soaring price of Chinese herbal medicines, the number of individual varieties has doubled. This phenomenon has attracted the attention of industry insiders. For the reasons for the first class of Chinese herbal medicines, some industry insiders believe that due to the impact of the new crown epidemic, the import of some Chinese herbal medicines has been blocked, resulting in the intangibility of related varieties. In addition, the precipitation in 2020 is large, and the harvest of Chinese medicinal materials is generally not as good as the previous year, and the supply is tight, **natural**.
In this context, the National Health Commission and the State Administration of Traditional Chinese Medicine organized experts to analyze and judge the work after the outbreak of the new crown epidemic, successively formulated and revised a series of diagnosis and treatment plans, jointly issued an announcement, and officially promulgated the 2020 edition of the Pharmacopoeia of the People's Republic of China. Compared with the previous edition, the content of the new edition of the Pharmacopoeia has undergone many new adjustments, among which the improvement of the quality and standards of traditional Chinese medicine is the key content.
In this context, the quality of traditional Chinese medicine must be strictly controlled, and the view that the quality of traditional Chinese medicine will become an important influencing factor is increasingly recognized and valued by traditional Chinese medicine enterprises.
In addition, the project technology: membrane separation process has a wide range of application prospects in the application of traditional Chinese medicine. Membrane separation systems achieve separation by selectively using the difference in molecular weight of chemical components of membranes. In terms of traditional Chinese medicine applications, it mainly filters bacteria, particles, polymer impurities and decolorization. Compared with the traditional alcohol oil process, the process eliminates the various processes of the alcohol sinking process, achieves the complicated purpose, maintains the boiling and compound formula of traditional Chinese medicine, and has the characteristics of easy drying, less hygroscopicity, less added excipients, saving a lot of ethanol and corresponding equipment, shortening the production cycle, reducing the process and personnel, and saving heat.
Glycine has a simple structure in the amino acid series, the human body is not an essential amino acid, and has both acidic and basic functional groups in the molecule. According to the glycine manufacturing process and product purity, it can be divided into four types of products: food grade, pharmaceutical grade, feed grade and industrial grade. The production, use and utility value of glycine have attracted more and more attention around the world. The production of food, medicine, medicine, fertilizer, pesticide, feed, etc. in many countries has been inseparable from its joining, or the use of its special effects cannot change the taste or quality of the product.
In order to obtain food-grade and pharmaceutical-grade glycine purification products, a microfiltration system or ultrafiltration membrane separation system is designed to remove glycine impurities. In the process of glycine purification, after the removal of powder activated carbon and the purification of microfiltration technology, the glycine products were subjected to high magnification microscopic detection, and no residual activated carbon particles were found to fully meet the quality requirements of the export products.
To sum up, the main reasons for the import of Chinese herbal medicines are the obstruction of imports caused by the epidemic and the poor harvest caused by climatic factors. At the same time, the country's strict control of the quality of traditional Chinese medicine will also become an important factor affecting traditional Chinese medicine. In the application of traditional Chinese medicine, membrane separation technology has a wide range of application prospects. The production and use of glycine as an important amino acid has attracted worldwide attention. In order to obtain high-quality glycine products, a microfiltration system and an ultrafiltration membrane separation system are used for purification.
