Abstract

The invention relates to a detection method for compound radix salviae miltiorrhizae dripping pills through quantitative analysis of multiple components by single marker; the method is a content determination method for six kinds of phenolic acid components through UPLC and quantitative analysis of multiple components by single marker; protocatechualdehyde is adopted as a single calibration object in experiments, and determination is carried out through a method with an external standard method and a correction factor; the method provides an effective and accurate quality control method for pharmacodynamic substances of the compound radix salviae miltiorrhizae dripping pills.

Description

technical field [0001] The invention relates to a drug detection method, in particular to a one-test, multiple-evaluation detection method for compound danshen dripping pills. The method includes a UPLC one-test, multiple-evaluation content determination method for six phenolic acid components. Background technique [0002] Due to the complexity of phytochemical components, multi-index content determination has become a consensus for the quality control of plant-derived drugs. At present, more and more domestic and foreign botanical drug standards include multi-index content determination. However, in the process of implementing the multi-index content determination method, the consumption of reference substances is large, and the detection operation is difficult, which seriously restricts the popularization and application of this method. [0003] To solve the above problems, people are actively looking for alternative methods. The researchers found that the ratio of the ...
