Problems solved by technology

These descriptions on the color indicators of decoction pieces are relatively "fuzzy", and have not reached the data-based and standardized measurement standards, so they cannot be accurately grasped
[0009] The method based only on human vision is not objective and is affected by the environment and the observer itself, but also the description of color indicators is "fuzzy", which has not reached the measurement standard of dataization and standardization, and cannot be accurately grasped. Therefore, in the production process of traditional Chinese medicine , is not conducive to the implementation of process standardization, and the quality of decoction pieces cannot be stably controlled; there is no judgment standard in the supervision of decoction pieces, which makes law enforcement difficult.

Embodiment 1

[0034] Embodiment 1 Determination of the color parameter range of gardenia decoction pieces

[0035] 1.1 Instrument and measurement conditions

[0036] Instrument CM-5 spectrophotometer (Konica Minolta Co., Ltd., Japan), equipped with Spectric-Magic NX workstation.

[0037] Measuring conditions The light source is a pulsed xenon lamp, the light source is D65, the standard observation angle is 8°, and the illumination aperture is Φ3mm. The instrument error ΔΕ*ab is within 0.6; the measurement wavelength range is 360-740nm; the repeatability standard deviation ΔΕ*ab is within 0.07; the inter-instrument standard deviation ΔΕ*ab is 0.15. The lighting system is SCI (specular componetnt included) reflected light mode with specular light and specular componetnt excluded (SCE).

[0038] 1.2 Pieces

[0039]Gardenia decoction pieces (34 batches of raw products, 34 batches of stir-fried products, 36 batches of burnt products, and 32 batches of charcoal products) were collected from ma...

Embodiment 2

[0089] Correlation analysis of embodiment 2 Gardenia pericarp and seed color

[0090] Since the original color data of the peels and corresponding kernels of gardenia decoction pieces (raw gardenia, fried gardenia, burnt gardenia, and gardenia charcoal) did not satisfy the normal distribution, the Spearman's rho correlation coefficient of single factor correlation analysis was used to explore Correlation between internal and external colors of different decoction pieces of Gardenia jasminoides. See Table 14 for the correlation coefficient results between the kernels (L*n, a*n, b*n) and peel color variables (L*w, a*w, b*w) of each decoction pieces of Gardenia jasminoides.

[0091] Table 14 Correlation analysis results of peel and seed color of Gardenia decoction pieces

[0092]

[0093] The results showed that the Spearman's rho grades corresponded one-to-one between the three sets of color parameter parameters (L*w—L*n, a*w—a*n, b*w—b*n) of raw gardenia pericarp and corres...

Embodiment 3

[0095] Embodiment 3 The establishment of the mathematical discriminant formula of processing degree of Gardenia jasminoides

[0096] In order to establish a mathematical model of the processing degree of decoction pieces. Based on the reference value range of each grouping of Gardenia (raw Gardenia, fried Gardenia, burnt Gardenia, and Gardenia Charcoal), the collected color data of different pieces of Gardenia were analyzed using the typical discriminant analysis (Discriminant) method. Discriminant function - Bayes (Bayes) discriminant rule to establish a mathematical discriminant function model for judging the degree of processing of different gardenia decoction pieces, and then use the ordinary method (Original) and cross-validated (Cross-validated) to analyze each color data of each gardenia decoction piece authenticating.

[0097] According to the original color data collected from different decoction pieces of Gardenia, through discriminant analysis, the mathematical dis...

Abstract

Aiming at the technical problem that in the prior art, the traditional Chinese medicine Gardenia adopts color observation based on personal experience as the only control method during the processing and production process, thus lacking objectivity, the present invention introduces a technology that can accurately quantify the appearance color of the traditional Chinese medicine. The peel and kernel of each decoction piece adopt the method of direct color measurement, quantify its color data, and through statistical calculation, determine the mathematical discriminant function of Gardenia jasminoides for online control in the process of processing gardenia decoction pieces. Applying this method to the on-line production of Gardenia jasmine can ensure the stability of the quality of Gardenia decoction pieces, has the advantages of being objective, fast and reliable, and solves the technical problem of lack of objectivity in human judgment in the prior art.

Description

technical field [0001] The invention relates to the field of processing technology and quality control of traditional Chinese medicine decoction pieces, in particular to a discrimination method using color data as an important index to control the processing degree of gardenia decoction pieces. Background technique [0002] Gardenia is the dried and mature fruit of Gardenia jasminoides Eills, a Rubiaceae plant. It is clinically used for fever and upset, jaundice, red urine, bleeding pain, conjunctival congestion, swelling and pain, fire poison sores, and external treatment of sprains and contusions. The common decoction varieties of gardenia are raw gardenia, fried gardenia, burnt gardenia and gardenia charcoal. Studies have shown that the chemical components of gardenia are mainly iridoids (geniposide, genipinic acid, genipin gentiobioside, etc.), diterpene pigments (crocin, saffron acid, etc.), in addition to flavonoids (gardenia, rutin, etc.), organic acids (chlorogenic...
