Problems solved by technology

However, the production of traditional Chinese medicine is mostly affected by complex and changeable natural and human factors, and most of the sensory indicators, chemical indicators, and activity indicators do not show a linear correlation with the grade of medicinal materials. Inferior, unable to realize the method of industrialized traditional Chinese medicine quality grade discrimination

Embodiment 1

[0079] Embodiment 1 Chinese medicine cassia twig quality grade detection method

[0080] (1) Sample preparation: take about 0.3g of cassia twig powder (passed through a No. 4 sieve), accurately weigh it, put it in a stoppered Erlenmeyer flask, add 50mL of methanol precisely, seal it tightly, weigh it, and ultrasonically treat it (power 140w, Frequency 42kHz) for 30 minutes, let cool, weigh again, make up the lost weight with methanol, shake well, filter, take the filtrate to obtain the sample solution.

[0081] (2) Adopt ultra-high liquid chromatography to collect the integral data of cassia twig fingerprint spectrum: adopt ultra-high liquid chromatography, under the characteristic wavelength 254nm of the main component of cassia twig, use octadecylsilane bond silica gel as filler; use 0.1 % formic acid-water solution is the mobile phase A, acetonitrile is the mobile phase B, and the gradient elution is carried out according to the following conditions: time 0-2min, the volume...

Abstract

The invention discloses a method for detecting the quality level of traditional Chinese medicine. According to the technical scheme of the present invention, by establishing the relationship between the main components of traditional Chinese medicine and the in vitro activity, the quality control index components of Chinese medicine and the level of in vitro activity related to drug efficacy are determined, and the clustering status of samples is determined by principal component analysis. A large number of sample data of different batches of traditional Chinese medicines were used to construct a logistic regression model between quality grades, index components, and biological activities, and to establish corresponding formulas for the detection of grades of Chinese medicinal materials. The Chinese medicine grade detection method proposed by the present invention can realize the mathematical expression of the quality difference standard of Chinese medicine, and finally can provide a feasible solution path for industrial evaluation of the quality grade of medicinal materials or decoction pieces.

Description

technical field [0001] The invention designs a method for detecting the quality level of traditional Chinese medicines, in particular relates to a method for the quality level of traditional Chinese medicines based on the interaction relationship of "ingredients-efficiency", and belongs to the technical field of traditional Chinese medicine detection. Background technique [0002] Traditional Chinese medicine resources are national strategic resources and the material basis of Chinese medicine for the survival and development of the Chinese medicine industry and the Chinese medicine industry. Therefore, the establishment of a "perfect standardization evaluation system of traditional Chinese medicine" is an important means to get rid of the embarrassing situation of uneven quality sources of traditional Chinese medicine, single quality control method of traditional Chinese medicine, and unstable curative effect level of traditional Chinese medicine. The quality standardizatio...
