Method for detecting quality of traditional Chinese medicine decoction by means of relative density

Abstract

The invention relates to a method for detecting quality of traditional Chinese medicine decoction by means of a relative density, and can effectively solve the problem of traditional Chinese medicine decoction quality detection. The method comprises the steps of: measuring a water absorption coefficient of traditional Chinese medicine decoction pieces; calculating a water adding amount during the decoction of the traditional Chinese medicine decoction, and measuring a traditional Chinese medicine decoction piece conversion relative density platform value; measuring a decocting rate of the traditional Chinese medicine decoction; calculating a relation between the decocting rate of the traditional Chinese medicine decoction and a prescription dosage; and detecting the relative density of the traditional Chinese medicine decoction, wherein a theoretical relative density of the decoction can be calculated when total weight of a prescription, dosages of the decoction pieces in the prescription and unit conversion relative density platform value are known, and whether the quality of the traditional Chinese medicine decoction meets the requirement can be determined by comparing the actual measured relative density with the theoretical relative density. The method provided by the invention is novel and unique, easy in operation and stable and reliable, has good detection effect, is high in accuracy rate, and is the innovation in quality detection of the traditional Chinese medicine decoction.

Description

technical field [0001] The invention relates to medicine, in particular to a method for detecting the quality of traditional Chinese medicine decoction by relative density. Background technique [0002] Traditional Chinese medicine decoction refers to the liquid dosage form made by decocting the decoction pieces to remove the residue and extract the juice. It has a long history and is widely used. Because the decoction is easy to prepare, quick to take effect, flexible in addition and subtraction, and can meet the needs of TCM syndrome differentiation and treatment, it is accepted by the majority of patients. [0003] At present, the preparation of traditional Chinese medicine decoction is mostly the traditional method. After the prescription is formulated by the pharmacist, the patient takes it home and prepares it by himself, or it is decocted and distributed to the patient by a special person in the decoction pharmacy. The second method is increasingly popularized in var...

AI Technical Summary

Problems solved by technology

By studying a series of physical indicators that can reflect the quality of the decoction, the simple and feasible index of "relative density" is used to establish a prediction model, so as to realize the quality detection of traditional Chinese medicine decoctions, but so far no public reports and related patents have been seen.
