Embodiment 2

[0030]The mass fraction of the preparation of the mixed medicinal material D is: 30% of the mountain silver flower, the mass fraction of the preparation of the mixed medicinal material E: 80% of the mountain silver flower, 20% of the golden silver flower; the mass fraction of the mixed medicinal material F From: 30% of the silver flower, 30% of the golden silver flower; the mass fraction of the preparation of the mixed medicinal material G is: 30% of the mountain silver flower, 30% of the golden silver flower; the mass fraction of the preparation of the mixed medicinal material H is: Silver flower 20%, honeysuckle 80%; the mass fraction of the preparation of the mixed medicinal material I is: 0.014% of the mountain silver flower, 99.986% of gold and silver.

Embodiment 3

[0031]Example 3 The mass fraction of the preparation of the mixed medicinal material j was: 30% of the mountain silver flower, 2% of the gold and silver.

Embodiment 4

[0032]The mass fraction of the preparation of the mixed medicinal material K in Example 4 is: the mountain silver flower is 90%, and the golden silver flower is 10%.

[0033]The pre-treatment process of the mixed medicinal material L in Example 5 of the present invention is: take the market selling wild silver flower (Hubei food is a Tianjin Industry Co., Ltd., the ID volume is 0.0625g / ml) 30.7ml, and the reduced pressure distillation is concentrated to 3.07ml After concentrating 0.0307 ml, the mixed medicinal material obtained after 0.38 g of a mountain silver flour was added thereto. Among them, the mass fraction of the mountain silver flower was 95%, and the mass fraction of the gold and silver flower was 4.8%, and the other impurity content was 0.2%.

Abstract

The invention provides a method for identifying lonicerae flos and honeysuckle by a chemical oscillation fingerprint technology, which is characterized by comprising the following steps of (1) adding an oscillation system solution into a to-be-detected sample, uniformly mixing, and communicating the obtained mixed solution with an electrochemical workstation through an electrode to obtain a chemical oscillation fingerprint, and (2) carrying out pretreatment and characteristic parameter extraction on the chemical oscillation fingerprint spectrum, and establishing a regression relationship between the characteristic parameters and the content of lonicerae flos and / or honeysuckle in the to-be-detected sample. The method for identifying the lonicerae flos and the honeysuckle by the chemical oscillation fingerprint technology has the advantages of strong characteristics, high sensitivity, large parameter range and the like, and a simple and convenient method is provided for qualitative and quantitative analysis of the lonicerae flos and the honeysuckle; secondly, the sample does not need to be subjected to complex pretreatment during detection, the analysis cost is low, and further popularization and application of the method are facilitated.

Description

Technical field[0001]The invention belongs to the technical field of Chinese herbal medicine detection, in particular, involving a chemical oscillation fingerprint spectrum technology identification of mountain and silver flowers and honeysuckle.Background technique[0002]Honeysuckle and Mountain Silver Flowers are all honest, the two are similar, and the naked eye is difficult to distinguish. From the "China Pharmacopoeia" (2005 version), two flowers will enter the pharmacopoeia directory. Honeysuckle is a sneaked flower bud or a first-open flower, and the mountain silver flower is a macarone l.macranthoideshand-mazz., Red gland, the winter Lhypoglaucamiq., South China, Woodlin, Woodlinfiusadc. Or yellowish brown Dry flower buds or buds with the initial flowers in the winter lfiulvotomentosahsuets.c.. "China Pharmacopoeia" (2020 edition) stipulates that the content of the content of the content of the golden flower is ≥1.5%, phenolic acid ≥ 3.8% and wood rhubhane ≥ 0.050%; the conte...
