Embodiment Construction

[0052] 1. Establish the liquid chromatography fingerprint of ginseng in the place of origin

[0053] A. Establish the liquid chromatography fingerprint of ginseng in the place of origin

[0054] 1. Preparation of reference solution

[0055] Accurately weigh an appropriate amount of ginsenoside Re reference substance, add methanol to dissolve and make a 1.00 mg / mL reference substance solution.

[0056] 2. Preparation of standard solution

[0057] Put commercially available Changbai Mountain ginseng as a standard product in a drying oven at 60°C for 4 hours and heat to constant weight, crush and sieve, and collect powder samples below 80 mesh;

[0058] Accurately weigh 2.0g Changbai Mountain ginseng powder sample and add it to the automatic temperature-controlled solvent reflux liquid-solid extractor, add 100mL methanol for extraction for 5 hours, extract the solution by rotary evaporation to recover the solvent, and pour the concentrated solution into a 10mL volumetric flask;...

Abstract

The invention provides a method for identifying HPLC fingerprints for protecting ginseng of origin, which is characterized by comprising the following steps: A, establishing liquid phase chromatograph fingerprints of the ginseng of origin, namely using the ginseng in the same habitat as a standard, analyzing the ginseng by liquid phase chromatograph and establishing fingerprints; and B, detectinga sample, namely taking a ginseng sample to be detected, detecting the sample under the same conditions as the standard respectively to obtain a spectrogram of the detected sample, and analyzing the fingerprints of the detected sample and the standard by a direct observational method or fingerprints software as qualitative basis. The method has simple pretreatment for fingerprints of the ginseng medicinal material established by adopting the liquid phase chromatograph, multiple peak numbers and better separation degree, therefore, contents of main chemical compositions of the ginseng medicinal material have large difference caused by different growing geographic environments and climates. The HPLC fingerprints of the ginseng can provide reference for distinguishing high-end ginseng health-care products from origin places and non-origin places, and provide reference for establishing fingerprints of other traditional Chinese medicinal materials. The research of methodology shows that all the precision, the stability and the repeatability have better application prospect.

Description

technical field [0001] The invention relates to an HPLC fingerprint identification method used for the protection of ginseng in the place of origin, and belongs to the technical field of liquid chromatography analysis. Background technique [0002] Due to the rich nutritional value and pharmacological effects of ginseng, ginseng medicinal materials have always attracted much attention. In foreign markets, there have been many high-end health foods and health medicines made from ginseng medicinal extracts. Ginseng medicinal materials have also become one of the best-selling botanical preparations in the natural medicine market in Europe and America. However, ginseng from different origins has different components due to the influence of environmental climate, water and soil conditions, which leads to differences in clinical efficacy. Therefore, many unscrupulous traders use some non-origin ginseng as shoddy products, confusing the real ones with fake ones, which greatly end...
