Abstract

The invention discloses a liquid chromatography mass spectrometry quantitative detection method for determining effective components in Shenmai injection. A sample disclosed by the invention dispenses with a complex pretreatment process and is obtained by filtering through a microfiltration membrane with 0.2mum; in liquid chromatography separation, a water-acetonitrile system is used as a mobile phase and gradient elution is carried out; and the detection is realized by using a mass detector; and quantitative detection is carried out at the peak area by adopting an external reference method. The quantitative detection method disclosed by the invention has the advantages of high sensitivity, favorable accuracy and precision and simplicity, convenience and quickness in operation; and the real-time detection in the production process of medicines is better realized.

Description

technical field [0001] The invention relates to a quantitative detection method of characteristic components in traditional Chinese medicine injections, in particular to a quantitative detection method of borneoside, a characteristic component of Radix Ophiopogon japonicus in Shenmai injections. Background technique [0002] The active ingredients of Shenmai injection are mainly saponins (about 7.5% of solid content), flavonoids and sugar compounds, among which saponins have been found to be represented by ginsenosides-Re, Rb1, Rb2, Rg1, Rg3, etc. 39 kinds of ginsenosides and 7 kinds of radix radix saponins represented by ophiopogon saponin D, and the flavonoids that have been found so far are mainly methyl radix dihydrohomoisoflavone B, 2β- 8 kinds of high isoflavone components represented by hydroxymethyl radix dihydrohomoisoflavone A, 2α-hydroxymethyl radix dihydrohomoisoflavone A, etc. [0003] The current implementation standard is the National Drug Standard (Revised) ...
