Problems solved by technology

Due to the large difference in properties of the seven components of the compound Danshen preparation, water-soluble components (salvianolic acid B, danshensu, notoginsenoside R 1 , Ginsenoside Rg 1 , Ginsenoside Rb 1 ) and fat-soluble components (tanshinone I and tanshinone IIA), and the content is quite different, so it is difficult to use a pretreatment method to process and detect
As a result, the current research on the detection method of the main components of the compound Danshen preparation usually adopts the method of pretreatment and detection of different components separately, the process is complicated and the steps are cumbersome

Abstract

The invention relates to a mass spectrometric detection method for plasma or tissue concentrations of seven components of a compound salvia miltiorrhiza preparation. The method comprises the followingsteps of (1) preparing a stock solution, namely respectively dissolving standard substances tanshinone I, tanshinone IIA, salvianolic acid B, tanshinol, notoginsenoside R1, ginsenoside Rg1 and ginsenoside Rb1 in a (80 + / -5)% methanol aqueous solution to prepare the standard substance stock solution; dissolving carbamazepine in a (80 + / -5)% methanol aqueous solution to prepare a carbamazepine stock solution; (2) preparing a working solution; (3) preparing a to-be-detected sample solution; (4) carrying out liquid chromatography separation on the to-be-detected sample solution obtained in the step (3); and carrying out mass spectrometric analysis on the sample after liquid chromatography separation. In the detection process of the method, the chromatographic peak shape is excellent, a channel of each compound only has a unique target peak, the interference of other effects, such as solvent effects, etc., is avoided, and the method is easy to operate and rapid to analyze, and is high in specificity and high in separation degree.

Description

technical field [0001] The invention relates to the technical field of drug analysis, in particular to a mass spectrometry detection method for plasma or tissue concentrations of seven components of a compound salvia miltiorrhiza preparation. Background technique [0002] Compound Danshen preparation is composed of 3 traditional Chinese medicines of Danshen, Panax notoginseng and Borneol.
