Problems solved by technology

Although where conditions permit, some hospitals and outpatient clinics have finished compound decoction products in reserve, which can be consumed only by heating. However, the curative effect of each pair of compound decoction finished products is fixed and cannot be mixed according to various diseases. Flexibility Poor, when storing the finished compound decoction at the same time

Abstract

The invention provides a preparation method and an application of a non-decocted fructus psoraleae preparation and belongs to the technical field of traditional Chinese medicine preparation. The preparation method of the non-decocted fructus psoraleae preparation comprises steps as follows: primary extraction of effective ingredients is performed in a mode of combination of water immersion and ultrasonic extraction, secondary extraction is performed through ethanol extraction, and the non-decocted fructus psoraleae preparation is obtained through concentration, drying and superfine grinding finally. The preparation can be used for preparing a compound preparation containing fructus psoraleae or fructus psoraleae extracts. Therefore, the problem that the utilization rate of raw materials is low, the effective ingredients are severely damaged and the extraction efficiency is not high when a conventional single method is adopted for extraction are solved, the whole technological process is simple to control, synergistic interaction of the steps is realized, accordingly, the active ingredients of the fructus psoraleae are effectively protected, and the availability of a finished product is improved better.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine preparation, and in particular relates to a preparation method and application of a psoraleae-free decoction preparation. Background technique [0002] Traditional Chinese medicine is the crystallization of the wisdom of the Chinese nation and has made great contributions to the protection of people's health. The traditional dosage forms of traditional Chinese medicine include pills, powders, ointments, liquors, etc., but most of the traditional dosage forms have shortcomings such as large dosage, thick dosage form, and poor appearance. The pace of development, the introduction of high technology, and the use of new technologies to improve the quality of traditional Chinese medicine are one of the important ways to reform the formulation of traditional Chinese medicine. [0003] Psoraleae is the dry and ripe fruit of leguminous plants. It is warm in nature, pungent and bitter...
