Abstract

The invention provides a method for measuring content of eighteen ingredients of Huangqi Jianzhong Wan (astragalus mongholicus pill for invigorating the stomach and regulating the middle warmer). Themethod includes the steps of subjecting the Huangqi Jianzhong Wan to ultrasonic extraction and centrifugation, extracting the liquid supernate, detecting the liquid supernate by an ultra performance liquid chromatography-tandem mass spectrometry positive and negative ion mode, preparing a mixed standard product solution from standard products of the eighteen ingredients, building a standard curve,and carrying out the methodological study. The method can realize measuring the eighteen ingredients of the Huangqi Jianzhong Wan, namely ononin, formononetin, calycosin, calycosin-7-glucoside, pterocarpan, astraisoflavan-7-O-beta-D-glucoside, isoflavane, isoliquiritin, liquiritigenin, liquiritin, glycyrrhetinic acid, cinnamic acid, isomucronulatol 7-O-beta-glucoside, astragaloside I, astragaloside II, astragaloside III, astragaloside IV and gallic acid. In the method, the sample pre-treatment process is simple and accordingly time for measurement is short; the method has the advantages of high specificity, high flexibility, good reproducibility and short analysis time, and can be applied to monitoring of production quality of the Huangqi Jianzhong Wan.

Description

technical field [0001] The invention relates to the technical field of detection of traditional Chinese medicine components, in particular to a method for determining 18 components in Huangqi Jianzhong Pills by ultra-high performance liquid chromatography tandem mass spectrometry. Background technique [0002] Huangqi Jianzhong Pill is derived from Zhongjing Jingfang Huangqi Jianzhong Decoction. The whole prescription is composed of five herbs of Astragalus, cinnamon, white peony root, roasted licorice and jujube. Clinically, it is mainly used to invigorate qi and dispel cold, invigorate the stomach and harmonize the middle. Insufficient Qi, shortness of breath, aversion to cold, abdominal pain and weakness. Modern pharmacological studies have shown that it is effective in treating gastrointestinal diseases caused by spleen deficiency; in addition, studies have shown that Huangqi Jianzhong Pills also have sedative and antispasmodic effects, lowering blood sugar, regulating ...
