Problems solved by technology

But there are also many shortcomings, such as the problems of high decoction temperature, long time, and large energy consumption; in terms of retaining active ingredients and removing ineffective ingredients, there are large loss of active ingredients, long cycle, many processes, and low extraction rate. The problem is not high; at the same time, the extract contains more impurities, which brings inconvenience to the next step of refining, thus affecting the extraction rate of active ingredients; the commonly used water extraction and alcohol precipitation method to remove impurities and refine, due to the use of a large amount of organic solvents, the safety is poor, Recycling is cumbersome, costly, and seriously pollutes the environment

The original process of preparing the active ingredients of Radix isatidis is produced by decoction and ethanol precipitation, which has many disadvantages such as high decoction temperature, long time, large energy consumption, large loss of active ingredients, many processes, low extraction rate, and environmental pollution. The product qualification rate is extremely low, resulting in high product costs and affecting the economic benefits of the enterprise
