Discussion on the application of microwave technology in the processing of traditional Chinese Medicine

Microwave drying technology was used to prepare Naoliqing pill (containing aromatic components), Guanlian pill (containing animal glue and organ components), Maren pill (containing oil components), Wuziyanzong pill (containing sugar and lipid components) and Qingshen xiaopang pill (containing extract) of concentrated Shuimi pill in three batches The researchers found that in the process of rapid microwave heating and drying, the pressure difference between the internal and external steam of pills can be formed (that is, the internal steam pressure is greater than the external steam pressure), which can produce certain swelling effect on pills, which is conducive to accelerating the dissolution speed of pills According to Chinese Pharmacopoeia, the dissolution time limit of Maren pill and Qingshen xiaopang pill shall not exceed two hours, while the finished products dried by microwave shall be dissolved within one hour, and the appearance and content of the products dried by microwave conform to the relevant regulations In flowers, the water content of petals is relatively small, the tissue is tender and easy to dry, while the water content of flower heads is large (the average water content is about 80%), the tissue is aging, not easy to lose water, and difficult to dry The results showed that the combination of Micro Sprinkling and air flow could significantly improve the quality of flower medicine For example, using this method to dry chrysanthemum can overcome the shortcomings of traditional methods, such as excessive drying of petals, easy falling off of petals, poor quality of finished products, etc., and the cost of using this technology to dry chrysanthemum is only 2 yuan / kg Traditional Chinese medicine needs to be processed before it can be used as a medicine, which is a major feature of traditional Chinese medicine The researchers of Chengdu University of traditional Chinese medicine have developed the microwave processed aconite with good quality, low toxicity and high curative effect by using the modern microwave drying technology, and have made a comparative analysis on the properties of the processed aconite, jiangyoubai and Hongkong processed by the traditional drying method The results showed that the proportion of water-soluble matter and petroleum ether soluble matter increased obviously, while the content of c4h10o soluble matter, which was mainly toxic diester type of aconite essence, had little change, which indicated that microwave processing made the medicine material loose, the dissolution rate of effective components increased, and the toxic components were destroyed at the same time However, the content of petroleum ether solute in jiangyoubai and Hong Kong paofuzi also increased, but the increase of water solute was not obvious, and the proportion of c4h10o solute was large On the one hand, the processing soaking time is too long and the components are lost; on the other hand, the components are not easy to dissolve because of the dense cell structure.
