Problems solved by technology

In recent years, the market demand for Jinbuhuan has continued to increase, wild resources have decreased year by year, and the development of artificial cultivation has slowed down, resulting in a sharp decline in the reserves and output of Jinbuhuan resources, resulting in many fake and inferior products on the market. Giving Jinbuhuan quality and medication safety and effectiveness Sexuality has brought a great impact, and it has become a bottleneck restricting the development of Jin Bu Huan medicinal material series
At present, the traditional identification methods for the morphological characteristics and physical and chemical properties of this medicinal material have certain limitations, and are not enough to control the quality of Jinbuhuan as a whole. As a commonly used clinical traditional Chinese medicine, its authenticity is affected by many factors, so it is necessary to Establish a scientific quality inspection method to evaluate the quality of Jinbuhuan

Embodiment 1

[0023] Establishment of Standard Fingerprints

[0024] 1 Instruments and reagents

[0025] 1.1 Instrument

[0026] High performance liquid chromatography: Shimadzu LC-20A, equipped with UV detector, chromatographic workstation, Japan Shimadzu; ultrapure water manufacturing system: Chengdu Yuechun Technology Co., Ltd.; CNC ultrasonic cleaner: KQ-500DB, Kunshan City Ultrasonic Instrument Co., Ltd.; Electric Heating Constant Temperature Blast Drying Oven: 101-1-S, Shanghai Yuejin Medical Instrument Factory; Low Temperature Coolant Circulating Pump: DLSB-5 / 20, Zhengzhou Great Wall Technology Industry and Trade Co., Ltd.; Circulating Water Vacuum Pump: SHZ -D(III), Gongyi Yingyu Yuhua Instrument Factory; Electric constant temperature water bath: GSY-n stainless steel, Beijing Medical Equipment Factory; Vacuum drying oven: D2F-250, Zhengzhou Great Wall Science, Industry and Trade Co., Ltd.; electronic analytical balance : ME215S, Beijing Sartorius Instrument System Co., Ltd.; mult...

Embodiment 2

[0058] The determination method of the fingerprint of Jinbuhuan reference medicinal material is the same as that of the standard fingerprint of Jinbuhuan medicinal material, and the sampling time is 60 minutes. The standard fingerprint and common pattern of Jinbuhuan medicinal material obtained in Example 1 were used as the basis for identification, and the differences between the two were compared. The results showed that the fingerprints of the Jinbuhuan control medicinal materials provided by the Food and Drug Inspection Institute of Guangxi District ( image 3 ) is not significantly different from the standard fingerprint, see Table 5.

Embodiment 3

[0061] The determination method of commercially available Jinbuhuan is the same as the determination method of Jinbuhuan standard fingerprint, and the sampling time is 60 minutes. The standard fingerprint and common pattern of Jinbuhuan medicinal material obtained in Example 1 were used as the basis for identification, and the differences between the two were compared. The result shows: commercially available Jinbuchang fingerprints (see Figure 4 ) is quite different from the Jinbuhuan standard fingerprint, in which the number of main peaks, the relative retention time of the main peaks, and the relative peak area are all quite different, and there are many common peaks that do not appear, see Table 6.

Abstract

The invention discloses a quality detection method of a stephania epigaea medicinal material. The method consists of: a. establishing a stephania epigaea standard fingerprint spectrum; b. determining the fingerprint spectrum of a to-be-tested stephania epigaea sample; c. comparing the fingerprint spectrum of the to-be-tested stephania epigaea sample with the stephania epigaea standard fingerprint spectrum, and screening Emilia sonchifolia medicinal material according with the Emilia sonchifolia standard fingerprint spectrum. The invention aims to provide important judgment basis for overall and comprehensive evaluation of medicinal materials through multi-component quality detection of stephania epigaea medicinal material, and ensures reliable quality and safe and reliable clinical efficacy. The method provided by the invention can be used for multi-component quality detection and control of stephania epigaea medicinal material, and provides important judgment basis for overall and comprehensive evaluation of the medicinal material.

Description

technical field [0001] The invention mainly relates to a method for detecting the quality of Jinbuhuan medicinal materials. Background technique [0002] Guangxi's characteristic medicinal material, Jinbuhuan, is the root tuber of Phalaenopsis genus Jinbuhuan, also known as Dirong and Shangui. It is mainly distributed in Guangxi, Yunnan, Sichuan and other places. It grows at an altitude of 480 meters and is found on rocky mountains in limestone areas. In recent years, the market demand for Jinbuhuan has continued to increase, wild resources have decreased year by year, and the development of artificial cultivation has slowed down, resulting in a sharp decline in the reserves and production of Jinbuhuan resources, resulting in many fake and inferior products on the market. Giving Jinbuhuan quality and medication safety and effectiveness Sexuality has brought a great impact, and it has become a bottleneck restricting the development of Jin Bu Huan medicinal material series.
