Abstract

The invention relates to a method for determining paclitaxel or paclitaxel, in particular to a method for quantitatively analyzing paclitaxel or paclitaxel by adopting a high-performance liquid chromatography-triple quadrupole mass spectrometry combination technology. The method comprises the steps of using a mobile phase containing ammonium formate and formic acid in a high-performance liquid chromatograph, adopting an MRM mode to determine formate added quasi-molecular ion peaks and daughter ion peaks of the paclitaxel or paclitaxel in an ESI (-) or APCI (-) ionization mode.

Description

technical field [0001] The invention belongs to the field of drug analysis and relates to a method for determining docetaxel or paclitaxel. More specifically, it relates to a method for quantitative analysis of docetaxel or paclitaxel based on high performance liquid chromatography-triple quadrupole mass spectrometry (LC-MS) technology. Background technique [0002] Docetaxel and paclitaxel are taxane anticancer drugs, which are a class of natural products extracted from the bark of Yew brevifolia. They are clinically used to treat breast cancer, non-small cell lung cancer, pancreatic cancer, gastric cancer, ovarian cancer and head and neck cancer. cancer etc. [1-2] . Its mechanism of action is to promote tubulin to form stable microtubules by binding to tubulin of tumor cells, while inhibiting its depolymerization, blocking cell mitosis, and inhibiting and killing tumor cells [3] . [0003] According to the results of literature review, the quantitative analysis method ...
