摘要: 目的 研究灯盏花乙素在胃肠道的代谢物。方法 分别用盐酸、β-葡糖醛酸苷酶水解灯盏花乙素,并用健康志愿者的肠内菌对灯盏花乙素进行转化,用超高效液相-串联质谱联用法分析代谢物。结果 灯盏花乙素可被盐酸、β-葡糖醛酸苷酶水解为苷元,可被肠内菌群转化为苷元。健康受试者口服灯盏花乙素后,血浆中能检测到灯盏花乙素苷元。结论 健康受试者口服灯盏花乙素后,在吸收进入血液之前,胃肠道内灯盏花乙素与其苷元并存,而苷元更易于吸收,以总苷元为检测对象研究灯盏花乙素药代动力学是合理的。

Abstract: AIM: The metabolites of scutellarin were studied in gastrointestinal tract.METHODS: Scutellarin was hydrolyzed with hydrochloric acid andβ-glucuronidase.Human intestinal flora and scutellarin were incubated in vitro.The metabolites were identified by UPLC-MS/MS method.RESULTS: Scutellarin could be hydrolyzed with hydrochloric acid andβ-glucuronidase,and could be metabolized by human intestinal bacteria.A main metabolite,scutellarein,also was found in the plasma of healthy volunteers after oral administration.CONCLUSION: There were scutellarin and scutellarein in intestinal before absorption.It was suitable for scutellarin pharmacokinetic studies to determine scutellarein or total aglycone.

Key words: scutellarin, UPLC-MS/MS, acid hydrolysis, β-glucuronidase, intestinal bacteria metabolism
