Embodiment 1

[0067] Embodiment 1 Establishment method and methodological investigation of Phellodendron Phellodendron fingerprint

[0068] 1, the establishment method of Phellodendron Phellodendron fingerprint

[0069] The establishment method of Phellodendron Phellodendron fingerprint collection, comprises the following steps:

[0070] (1) Preparation of need testing solution: get 20 batches of cortex cortex from different origins in the above table 1 and pass through No. 3 pharmacopoeia sieve after pulverizing, get cortex cortex powder 0.2g, accurately weighed, place in 10mL volumetric flask, add methanol ( Containing 0.1% hydrochloric acid), set the volume to the mark, weigh, ultrasonically treat for 40min, cool to room temperature, make up the lost weight with methanol (containing 0.1% hydrochloric acid), shake well, centrifuge at 4000r / min for 10min, take the supernatant solution, through a 0.22 μm microporous membrane, and take the subsequent filtrate as the test solution;

Embodiment 2

[0108] Example 2 The detection and methodological investigation of the multi-wavelength quantitative components of Phellodendron Phellodendri fingerprint

[0109] 1. Detection of multi-wavelength quantitative components

[0110] The retention times of phellodine hydrochloride, magnolialine, and berberine hydrochloride were 20.173min, 20.948min, and 52.846min, respectively. Turn on the DAD detector for full-wavelength scanning, compare the peak areas of each drug efficacy index component under different wavelength conditions, and obtain the optimal detection wavelength of each index component, that is, detect the content of Phellodendron hydrochloride under the condition of 284nm wavelength, and detect the content of Phellodendron hydrochloride under the condition of 268nm wavelength For the content of magnolialine, the content of berberine hydrochloride was detected under the condition of 265nm wavelength.

[0111] 2. Research on multi-wavelength quantitative component detect...

Embodiment 3

[0154] Embodiment 3 Establishment of Phellodendron Phellodendri Chemical Pattern Recognition Method

[0155] 1. Identification of Cortex Phellodendron by Sequence Cluster Analysis (HCA)

[0156] Use the data management function of the Waters empower workstation to obtain relevant information such as the peak area and retention time of the components of Cortex Phellodendron and Cortex Phellodendri. Import the obtained data matrix into SPSS 19.0, and use the average connection pearson correlation (intra-group) connection to carry out hierarchical clustering analysis on the Phellodendron cork samples. The dendrogram is as follows Figure 4 shown. When the distance scale is about 22, Phellodendron Phellodendron and Phellodendron officinalis can be clearly distinguished, Phellodendron officinalis clustered into one type S3, Phellodendron officinalis clustered into two types S1 and S2. Through the investigation of the shape, thickness, color and texture of Phellodendron cork sampl...

Abstract

The invention discloses a cortex phellodendron chinese identification method. According to the identification method, cortex phellodendron chinese is used for preparing a solution of a test product, solutions in which a berberine hydrochloride reference substance, a phellodendrine chloride reference substance and a magnoflorine reference substance are dissolved are used as reference substance solutions, and through high performance liquid chromatograph measurement, liquid chromatograms of the solution of the test product and the reference substance solutions are obtained respectively; the obtained liquid chromatograms are guided into a traditional Chinese medicine chromatograph fingerprint similarity evaluation system for analysis, through analysis, a cortex phellodendron chinese fingerprint is obtained, and hierarchical cluster analysis or principal component analysis or partial least square analysis is adopted for processing data of the cortex phellodendron chinese fingerprint, so that classification identification is conducted on the cortex phellodendron chinese or processed products of the cortex phellodendron chinese. According to the cortex phellodendron chinese identification method, on the basis of building the cortex phellodendron chinese fingerprint, the cortex phellodendron chinese index component content is measured, and by combining different chemical mode identification methods, the cortex phellodendron chinese, the processed products of the cortex phellodendron chinese and fake cortex phellodendri amurensis can be effectively identified and distinguished.

Description

technical field [0001] The invention relates to the field of drug analysis, in particular to an identification method of Cortex Phellodendri and its application. Background technique [0002] Phellodendron chinense, the name of traditional Chinese medicine, is the dry bark of Phellodendron chinense Schneid. It was first recorded in "Shen Nong's Materia Medica", and it is commonly called "Sichuan Phellodendron", and it is mainly produced in Sichuan, Guizhou, Hubei and other places. The main active ingredients in Cortex Phellodendri are alkaloid compounds such as berberine hydrochloride and cortex cortex hydrochloride. Phellodendron Phellodendri is bitter and cold in nature and has the functions of clearing away heat and dampness, purging fire and removing steam, detoxifying and treating sores. As a traditional Chinese medicine, it is widely used in the market and clinical treatment. At present, the specifications and grades of Phellodendron cypress on the market are not cle...
