Rapid and One-Step Screening of Taxane Compounds by a Two-Dimensional Carbon Microfiber Fractionation System Combined with Tandem Mass Spectrometry

Autor: Zhao Wang, Meiyu Cui, Biao Ma, Lei Yang, Yingli Yu, Haiyan Cui, Dongri Jin, Haibo Shang, Donghao Li

Publikováno v: Journal of agricultural and food chemistry. 70(15)

Taxane compounds have attracted wide attention due to the basic chemical structure of taxol as an alternative anticancer drug. The full-scan tandem mass spectrometry (MS/MS) fragmentation behaviors of seven taxane compounds were studied. For taxanes
