Abstract

The invention belongs to the technical field of medicine analysis and specifically relates to an establishment method for a fructus forsythiae medicine fingerprint. The method specifically is realizedby the following steps of preparing a reference substance solution, taking appropriate amount of forsythin, forsythoside A, isoforsythiaside, rutin and forsythingenin reference substances, and preparing the reference substances into the reference substance solution; preparing a test sample solution, weighing fructus forsythiae medicine powder, carrying out heating reflux extraction, taking subsequent filtrate, carrying out filtering through utilization of filter membrane, taking the subsequent filtrate as a sample solution, measuring the sample solution and a puerarin water solution, and carrying out mixing uniformly to obtain the test sample solution; and carrying out detection through adoption of a high performance liquid chromatography and establishing the fingerprint. According to themethod, high performance liquid chromatography detection is carried out on the fructus forsythiae medicine through adoption of different gradient elution, a separation effect is good; through external addition of an internal standard, the established fingerprint has a semiquantitative function, so change of components among samples can be effectively expressed, and quality of the samples can be judged relatively precisely; and quality monitoring can be carried out on the raw material fructus forsythiae medicine relatively comprehensively.

Description

technical field

[0001] The invention belongs to the technical field of drug analysis, and in particular relates to a method for establishing fingerprints of forsythia medicinal materials. Background technique

[0002] Forsythia is the dried fruit of Forsythia suspensa (Thunb.) Vahl, which is a plant of Oleaceae. It is harvested in autumn when the fruit is first ripe and green, removed impurities, steamed, and dried. It is commonly called "Qingqiao"; the fruit is ripe Harvest in season, dry in the sun, remove impurities, commonly known as "Laoqiao" [1] . Forsythia has the effects of clearing heat and detoxifying, reducing swelling and dispelling stagnation, and evacuating wind-heat. [2] . Modern pharmacological research shows that forsythia has antibacterial, antiviral, anti-inflammatory, antipyretic, antiemetic, diuretic and other effects [3] . At present, Forsythia has definite curative effect, low toxicity and side effects, and wide range of uses and clinical applicat...
