摘要
本研究建立一种简便、快速、灵敏度高的超高效液相色谱串联四极杆-飞行时间质谱(UPLC-Q-TOF-MS/MS)法,研究树豆酮酸A(CAA)在大鼠体内的代谢特征.通过灌胃给予大鼠CAA(30 mg·kg1)后,收集血浆、尿液、胆汁和粪便采用UPLC-Q-TOF-MS/MS检测生物样品,收集和处理相关数据,将代谢产物的精确质量数和MS2质谱与母体化合物进行比较.结果共检测到23种代谢物,其中尿液中有15种,胆汁中有11种,粪便中有11种,血浆中有9种.与CAA相关的主要代谢途径包括脱氢、还原、羟基化、甲基化和葡萄糖醛酸结合.本实验获得贵州医科大学动物伦理委员会批准(编号:1603137).
Abstract
This research established a simple,rapid and sensitive ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS/MS)method to investigate the metabolic profiles of cajanonic acid A(CAA)in rats.After intragastric administration of CAA(30 mg·kg-1)to rats,the biological samples were detected by UPLC-Q-TOF-MS/MS.Relevant data was collected and processed,the accurate mass and MS2 spectra of the metabolites were compared with the parent compound.As a result,a total of 23 metabolites were detected,including 15 in urine,11 in bile,11 in feces,and 9 in plasma.The major metabolic pathways related to CAA included dehydrogenation,reduction,hydroxylation,methylation and glucuronide conjugation.This experiment was approved by Animal Ethics Committee of Guizhou Medical University(approval number:1603137).
