Problems solved by technology

Aware of this problem, some scholars have compared and evaluated the internal components of different varieties of chrysanthemums from the perspective of multi-index control, but the multi-component analysis brings comprehensive information and at the same time causes confusion.
This status quo cannot reflect the quality of chrysanthemums well, let alone the quality of Hangchrysanthemums.

Abstract

The invention relates to a construction method and a quality detection method of a UPLC feature map of a Hangzhou chrysanthemum medicinal material. The construction method comprises the following steps: sample solution preparation; taking the Hangzhou chrysanthemum medicinal material, crushing, adding a solvent for extraction and filtering, wherein a filtrate is taken as a sample solution; reference solution preparation: taking chlorogenic acid, 3,5-O-dicaffeoylquinic acid, 4,5-O-dicaffeoylquinic acid, galuteolin and linarin and adding a solvent for dissolution, wherein an obtained solution isa reference solution; ultra performance liquid chromatography detection: absorbing the sample solution and the reference solution, injecting into a liquid chromatograph and detecting to obtain the UPLC feature map of the Hangzhou chrysanthemum medicinal material. The UPLC feature map is rich in characteristic peak information, can fully reflect the chemical composition of the Hangzhou chrysanthemum medicinal material and can also effectively characterize the qualities of a Hangzhou chrysanthemum decoction piece and standard decoction and identify the product authenticity.

Description

technical field [0001] The invention belongs to the technical field of drug analysis, and in particular relates to a construction method and a quality detection method of a UPLC characteristic map of a chrysanthemum medicinal material. Background technique [0002] Chrysanthemum is the dry flower head of Chrysanthemum morifolium Ramat. Chrysanthemum was first recorded in "Shen Nong's Materia Medica" in the Eastern Han Dynasty, and was listed as top grade. It is said: "long-term use can benefit blood qi, make light of body, resist aging, and prolong life". For anemopyretic cold, headache and dizziness, conjunctival congestion and swelling pain, blurred vision, sore carbuncle and swollen toxin. The 2015 edition of the Chinese Pharmacopoeia contains five main medicinal chrysanthemums: "Gongju", "Chuju", "Boju", "Hangju" and "Huaiju". After consulting a large number of literatures, it is found that the types and contents of the main chemical components of chrysanthemums are d...
