Abstract

The invention relates to a construction method and application of a medicine Terminalia fruit and Terminalia chebula Retz.var.tomentella Kurt. medicinal material characteristic spectrum. The construction method of the medicine Terminalia fruit medicinal material specific chromatogram comprises the following steps: preparing a reference substance solution by taking gallic acid, ethyl gallate, corilagin, Chebulagic acid, myrobalan acid and chebulic acid as reference substances; dissolving a medicine Terminalia fruit in a solvent, performing ultrasonic extraction, filtering an extracting solution, and taking subsequent filtrate to obtain a medicine Terminalia fruit test solution; respectively carrying out ultra-high performance liquid chromatography detection on the reference substance solution and the medicine Terminalia fruit test solution. Chromatographic conditions of the ultra-high performance liquid chromatography comprise that a mobile phase A is acetonitrile, a mobile phase B is aphosphoric acid aqueous solution with a volume fraction of 0.1-0.3%, and an elution mode is gradient elution. The invention provides a comprehensive, effective and rapid method for controlling and evaluating the quality of the medicine terminalia fruit (collectively referred to as myrobalan).

Description

technical field [0001] The invention relates to the technical field of drug analysis and drug quality control, in particular to a construction method and application of a characteristic map of myrobalan and myrobalan tomentosa medicinal materials. Background technique [0002] Myrobalan (collectively referred to as) is a commonly used medicine of traditional Chinese medicine, and also a commonly used medicine of ethnic medicines such as Tibetan medicine and Mongolian medicine. According to the first part of the 2015 edition of "Chinese Pharmacopoeia", Myrobalan (collectively referred to as) is the Junziceae plant Terminalia chebula Retz .Or the dry ripe fruit of Terminalia chebula Retz.var.tomentella Kurt. Myrobalan (collectively) is bitter, sour, puckery in nature, flat, returns lung, large intestine meridian. It has the effects of astringing the intestines to relieve diarrhea, astringing the lungs to relieve cough, reducing fire and pharynx, and is clinically used for chr...
