中文摘要：

对南葶苈子标准品建立了UPLC／Q—TOF-MS／MS方法，根据质谱特征指认了14个化学成分，包括9个黄酮类，4个脂肪酸类和1个强心苷类，其中槲皮素-3．O-13-D-[6-O-芥子酰基-2-O-β—D-吡喃葡萄糖基]-吡喃葡萄糖苷为南葶苈子首次报道。

英文摘要：

A UPLC/Q-TOF-MS/MS method was developed for identifying the constituents in the Chinese herb Semen Descurainiae. A total of 14 compounds were identified or tentatively characterized based on their mass spectra, including 9 flavonoids, 4 fatty acids and 1 cardiac glycoside. Among them, quercetin-3-O-β-D-[6-O-sinnapoyl-2-O-β-D-glucopyranosyl]- glucopyranoside was identified in Semen Descurainiae for the first time.
