Embodiment Construction

[0042] The specific embodiments of the present invention will be further described in detail below in conjunction with specific circumstances.

[0043] The present invention in concrete implementation, comprises the following steps:

[0044] (1) Determination of water absorption of Chinese herbal medicine:

[0045] Take 17 kinds of Chinese herbal decoction pieces, 20g of each (taste), add 400ml of water, soak for 1h, filter, measure the volume of the filtrate, the decrease in the volume of the filtrate is the water absorption of the Chinese herbal decoction pieces, calculate the water absorption coefficient of each decoction piece, and the water absorption coefficient The calculation formula is: water absorption coefficient = water absorption / weight of decoction pieces, and the calculation results of water absorption coefficient of 17 kinds of traditional Chinese medicine decoction pieces are as follows:

[0046] Pieces Unit water absorption (ml / g) licorice ...

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...
