Problems solved by technology

[0004] The current quality control methods for this drug mostly use different chromatographic conditions to measure the content of one or two components, which has the disadvantages of cumbersome operation, long detection time, and high detection cost.
[0005] Daphne genkwa standard decoction is made by extracting, concentrating and drying the decoction pieces of a single Chinese herbal medicine. At present, there is no effective method for controlling the quality of Daphne genkwa standard decoction, and HPLC method has not been found in the prior art to simultaneously determine Daphne genkwa. Literature report on the determination of four chemical components in Daphne genkwa standard decoction by the characteristic map of flower standard decoction combined with one test and multiple evaluation method

Abstract

The invention relates to a construction method of a HPLC specific chromatogram of a daphne genkwa standard decoction and a component content determination method of the daphne genkwa standard decoction, and the component content determination method of the daphne genkwa standard decoction comprises the following steps: (1) respectively sucking a reference substance solution and a to-be-determineddaphne genkwa standard decoction sample solution, injecting the solutions into a high performance liquid chromatograph, and determining corresponding peak areas; (2) calculating the content of genkwanin through an external standard method; and (3) calculating the contents of apigenin-7-O-beta-glucuronide, apigenin and hydroxygenkwanin through a quantitative analysis of multiple components by single marker. According to the method, the content of genkwanin is calculated through an external standard method, and then the content of apigenin-7-O-beta-glucuronide, apigenin and hydroxygenkwanin is calculated through a quantitative analysis method, so that the operation steps of content determination of four components can be effectively simplified, the determination time is shortened, the working efficiency is improved, and quantitative analysis of chemical components of the genkwanin standard decoction is realized.

Description

technical field [0001] The invention belongs to the field of identification of traditional Chinese medicines, and particularly relates to a method for constructing an HPLC characteristic spectrum of a daisy flower standard decoction and a method for determining the content of its components. Background technique [0002] Coriander is the dried flower bud of Corianderaceae. Picked in spring when the flowers are not open, remove impurities, dry, wash and scrape off the rough skin while fresh, wash and dry; this product has the functions of purging water and drinking, detoxifying and killing insects. It is traditionally used to treat edema and accumulation of phlegm. and dyspnea cough embolism. Coriander is also known as Southern Coriander, Coriander Strip, Medicinal Fish Grass, etc. It was first recorded in "Shen Nong's Materia Medica" and listed as the lower grade. Modern medical research shows that the main medicinal components of fenugreek are flavonoids, which have vari...
