Embodiment 1

[0074] 1 Orthogonal test

[0075] White thorn fruit is the main counterfeit of black wolfberry. In order to obtain the reaction conditions for the maximum difference between the fingerprints of black wolfberry and its counterfeit white thorn fruit, the authentic medicinal material Qinghai black wolfberry and the main counterfeit white thorn fruit of black wolfberry were selected as test objects. The system similarity of the average value of the characteristic parameters of the fingerprints of the three parallel experiments under the same conditions is used as an investigation index, and L 25 (5 6 ) orthogonal table, with reference to Table 1, with reaction temperature (A), sample detection amount (B), sulfuric acid (C), manganese sulfate (D), acetone (E), sodium bromate ( F) Volume is used as 6 investigation factors, and 5 levels are selected for testing.

[0076] When the system similarity is smaller, it indicates that the difference between the characteristic parameter inf...

Abstract

The invention discloses a method for identifying genuineness and fake of lycium ruthenicum based on a nonlinear chemical fingerprint spectrum technology. The method comprises the following steps of respectively adding sulfate, manganese sulfate, acetone and sodium bromate solutions into lycium ruthenicum standard products from each production place, placing into a nonlinear chemical fingerprint spectrum intelligent analyzer, obtaining nonlinear chemical fingerprint spectrums of lycium ruthenicum from each production place, performing equal-length standard treatment on the nonlinear chemical fingerprint spectrums, and extracting feature parameter information; under the same condition of standard products, obtaining the nonlinear chemical fingerprint spectrum and feature parameter information of to-be-tested samples; according to the maximum relative standard deviation, visual shape difference and integral similarity of the fingerprint spectrums of the standard products and the to-be-tested samples, dividing the to-be-tested samples into genuine products, doubted products and fake products. The method has the advantages that the complicated pretreatment steps of separating, extracting and the like are not needed, the cost of the equipment is low, the whole content of all active ingredients can be represented in a cluster way, and the detection cost is low.

Description

technical field [0001] The invention relates to the field of black wolfberry identification, in particular to a method for authenticity identification of black wolfberry based on nonlinear chemical fingerprint technology. Background technique [0002] Lycium ruthenicum Murr. is the dry and mature fruit of Lycium ruthenicum Murr, a perennial shrub of the Solanaceae Lycium genus. It is mainly distributed in the Loess Plateau, Qinghai, Gansu, Ningxia, Xinjiang and Tibet in northern Shaanxi, China. It is a unique Medicinal and edible plants. Black wolfberry occupies a very important position in my country's traditional ethnic medicine. According to the records in the classic Tibetan medicine "Jingzhu Materia Medica": black fruit wolfberry is sweet in taste, calm in nature, clears heart heat, and has a significant effect on the treatment of heart fever, heart disease, irregular menstruation, menopause and other diseases. Modern pharmacology has proved that the fruit of Lycium b...
