Pulsatilla saponin D, an antitumor substance isolated from traditional Chinese herbal medicine Pulsatilla chinensis (Bge.) Regel, is a promising candidate for new drug development. The purpose of the present study is to establish a simple and practical strategy for the metabolite profiling of Pulsatilla saponin D in vivo. A total of 18 metabolites were identified in rat plasma, urine and feces samples based on MS and MS/MS data by using ESI-Q-TOF-MS/MS, and eight of them (M11-M18) were reported for the first time. The results indicated that deglycosylation, dehydrogenation, hydroxylation and sulfation were the major metabolic transformations of Pulsatilla saponin D in vivo. This study has improved our understanding of the metabolic fate of Pulsatilla saponin D in vivo, and the information gained from the current study is relevant to the pharmacological activity of Pulsatilla saponin D.
白头翁皂苷D是从传统中药白头翁中分离出的一种抗肿瘤物质,是新药开发的一个有前景的候选药物。本研究的目的是建立一种简单实用的体内白头翁皂苷D代谢物谱分析策略。利用电喷雾四级杆-飞行时间串联质谱(ESI-Q-TOF-MS/MS),基于质谱和串联质谱数据,在大鼠血浆、尿液和粪便样本中总共鉴定出18种代谢物,其中8种(M11-M18)为首次报道。结果表明,去糖基化、脱氢、羟基化和硫酸化是白头翁皂苷D在体内的主要代谢转化方式。本研究增进了我们对白头翁皂苷D在体内代谢命运的理解,并且从当前研究中获得的信息与白头翁皂苷D的药理活性相关。
