Method for preparing ultrasonic extracted Chinese medicinal preparation for treating qi deficiency

Abstract

The invention discloses a method for preparing an ultrasonic extracted Chinese medicinal preparation for treating qi deficiency, which belongs to the technical field of traditional Chinese medicaments. The method comprises the following steps of: crushing ginseng into coarse powder, putting the coarse powder into an ultrasonic extractor, adding 30 percent ethanol in an amount which is 3 times weight of the coarse powder, starting ultrasonic equipment at a temperature of between 20 and 25 DEG C, performing ultrasonic treatment for 40 minutes, filtering, reclaiming the ethanol, concentrating the filtrate to original amount, adding the ethanol in an amount which is 3 times weight of the concentrate, stirring, standing, taking the supernate, reclaiming the ethanol, and concentrating the supernate to 100ml; and adding sodium benzoate, stirring the solution uniformly, regulating the ethanol content to be 20 to 30 percent, standing at a temperature of between 5 and 10 DEG C, taking the supernate, filtering the supernate, adding water till 1,000ml, standing for 7 days at a temperature of between 5 and 10 DEG C, taking the supernate, filtering the supernate, and packing the supernate to obtain the preparation. By adopting the advanced ultrasonic extraction technology, the effective ingredients based on ginsenoside in the preparation are obviously improved, the quality and the curative effect of the medicament are improved, the clinical effect of the preparation is improved, the yield and the purity of the product are improved, the cost is saved, and the method is suitable for large-scale production operation.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicines, and in particular relates to a preparation method of an ultrasonically extracted traditional Chinese medicine preparation for treating qi deficiency. Background technique [0002] In the prior art, there are many mixture products in the market, but most of them are extracted by traditional techniques and decocted with water. During the decoction process, the effective substances that are easy to decompose will be lost, and the surface of the medicinal materials will be gelatinized. The internal active ingredients cannot be fully released. Therefore, making full use of medicinal materials, improving the efficacy of preparations, and reducing energy consumption are issues that every enterprise must overcome. For example, ginseng oral liquid (Standard of Food and Drug Administration: WS-1148 (ZD-1488)-2002), the prescription is as follows: ginseng 100g, sodium benzoate 3g. Pr...
