摘要:

人参皂苷Rb1是人参中的达玛烷型三萜皂苷类化合物, 具有多种生物活性. 对人参皂苷Rb1代谢产物的分析已有报道, 在大鼠尿液、粪便、胃和大肠中共检出了5种代谢产物. 本文采用高效液相色谱-飞行时间串联质谱进行人参皂苷Rb1的体内代谢研究, 通过口服和静脉给予药物, 在大鼠尿液中共检出了人参皂苷Rb1的14种代谢产物, 并系统分析和推断了这些代谢物的转化规律和可能结构.

Abstract:

The major metabolites of ginsenoside-Rb1 in rats urine were described. Urine samples were collected before and after 24 h of single oral administration of 150 mg and intravenous administration of 60 mg Rb1 to four rats, respectively. The samples were purified by SPE column and then were analyzed by liquid chromatography-ESI-mass spectrometry for potential metabolites. Parent drug and its fourteen metabolites were identified in rat urine based on the comparison of total ion chromatograms of the blank with the metabolic urine as well as mass spectra. Its main metabolic pathways and possible structures are analyzed in detail.

Key words: Ginsenoside-Rb1; LC/TOF-MS; Metabolite of drug
