Problems solved by technology

There are research reports pointing out that Achyranthes chinensis and Achyranthes bidentata are very different from Achyranthes bidentata in terms of chemical composition and pharmacological effects, and they cannot replace Achyranthes bidentata in medicine. Therefore, adulteration in the Achyranthes bidentata market has brought certain problems to clinical medication. potential safety hazards, and also brought great obstacles to the development and utilization of authentic Sichuan medicinal resources
[0004] The appearance and properties of amaranthus and mixed Achyranthes bidentata are similar to those of Achyranthes bidentata. When the medicinal materials are distributed in large quantities, they cannot be distinguished only by observation. Moreover, after being processed into decoction pieces or wine-cured decoction pieces, the original appearance of the medicinal materials basically disappears, giving a Inspection work brings certain difficulties
Existing research reports pointed out that the authenticity of Achyranthes bidentata was identified by HPLC characteristic fingerprints based on the characteristic differences in chemical composition between Achyranthes bidentata and A. , but the process is complex, time-consuming, and costly, and it is difficult to meet the requirements of rapid identification

Embodiment 1

[0029] Embodiment 1 Detection method of the present invention

[0030] Sample: Sample 1

[0031] Identification: Follow the steps below:

[0032] (1) Observe the color of the outer skin of the sample, which is light red, which is a positive result;

[0033] (2) Remove the outer skin of the sample, observe the color, and it is bright red, which is a positive result;

[0034] (3) Observe the color of the cross-section of the sample, it is bright red, which is a positive result;

[0035] (4) Take a part of the sample, taste it in the mouth, it is extremely bitter and extremely numb, which is a positive result;

[0036] (5) Foam test: Take an appropriate amount of sample, crush it, pass it through a No. 3 sieve, weigh 0.3 g, put it in a test tube, add 10 mL of water, shake vigorously for 1 min, and let it stand for 5 min. If a large amount of persistent foam is produced on the liquid surface, it is a positive result.

Abstract

The invention discloses a method for rapidly identifying the authenticity of radix cyathulae. The method disclosed by the invention comprises the following steps: observing or detecting following 5 indexes of a sample to be detected; determining whether the sample to be detected is a radix cyathulae certified product or not according to an identification result of the 5 indexes: (1) an epidermis color; (2) a color after the epidermis is removed; (3) a cross section color; (4) a mouth taste; (5) a foam test. The identification method disclosed by the invention keeps advantages that traditionalcharacteristic identification is simple and rapid, and is also combined with the foam test to make up the defects of poor feasibility of the traditional characteristic identification and sense organ judgment subjectivity; compared with the prior art, such as high performance liquid chromatography and ultraviolet spectrophotometry, the method has the advantages of simplicity in operation, short consumed time, high sensitivity, environment protection, energy saving and the like.

Description

technical field [0001] The invention relates to an identification method for rapidly identifying the authenticity of Chuan Achyranthes bidentata. Background technique [0002] Cyathula officinalis Kuan is the dried root of Cyathula officinalis Kuan, a plant in the Amaranthaceae family. It is recorded in the 2015 edition of the Chinese Pharmacopoeia. [0003] Achyranthes bidentata, as a well-known authentic medicinal material from Sichuan, has a large supply and demand in the market. However, due to historical introductions, there is a serious confusion in the varieties of Achyranthes bidentata in the market. Among them, Achyranthes bidentata is mixed with fake products for sale. The fake products of Achyranthes bidentata are mainly C.capitata Moq. and C.officinalis*C.capitata. There are research reports pointing out that Achyranthes chinensis and Achyranthes bidentata are very different from Achyranthes bidentata in terms of chemical composition and pharmacological effects,...
