Abstract

The invention provides a Clerodendrum fragrans HPLC standard fingerprint spectrum and building method and application thereof. The method comprises the following steps: preparing a test solution; preparing a reference substance solution; selecting color spectrum conditions; measuring by a high-performance liquid chromatograph so as to obtain the fingerprint spectrum of the Clerodendrum fragrans herbs; and comparing HPLC fingerprint spectrums of 11 batches of the Clerodendrum fragrans herbs to ensure the common fingerprint characteristics, thereby obtaining the standard fingerprint spectrum. The method has the characteristics of simplicity and convenience, good repeatability, multiple characteristic peaks, accuracy, reliability and the like; and the built standard fingerprint spectrum can effectively represent the quality of the Clerodendrum fragrans herbs.

Description

technical field [0001] The invention relates to the technical field of drug analysis, and more specifically, relates to a method for establishing an HPLC fingerprint of jasmine and a standard fingerprint thereof. Background technique [0002] Stinky jasmine (alias: stinky jasmine, stinky jasmine, big bunpo, single jasmine, crossing the wall wind), is the dry stem or root of the Verbenaceae plant stinky jasmine, which is a commonly used Chinese herbal medicine, and is now included in "Guangdong Province Chinese Medicinal Materials It has the effects of expelling wind and dampness, diuresis and swelling, and is often used to treat rheumatic bone pain, beriberi edema, bronchitis, hypertension, eczema, scabies, skin itching and other skin diseases. It is produced in various places in Guangdong Province, and Yangshan, Bao'an, Sanshui and other places produce more. Its rhizome can be used as medicine slightly bitter, flat. Return liver, spleen, kidney meridian, have the effect o...
