摘要:

黄芩素是黄芩苷的苷元, 是黄芩的主要活性黄酮类成分之一。大鼠灌胃给予黄芩素 (200 mg/kg)之后, 利用HPLC-DAD和LC-MS/MS法从大鼠血清中检测并鉴定出5个代谢产物 (M1-M5) 以及原型药 (M0)。在此结果上, 推测了黄芩素在大鼠血清中可能的代谢途径。

关键词: 黄芩素, 黄酮, 代谢产物, LC-MS/MS, HPLC-DAD

Abstract:

Baicalein, the aglycon of baicalin, is one of the main bioactive flavones in Scutellaria baicalensis Georsi. Five metabolites (M1-M5) and the parent drug (M0) were identified in rat serum after oral administration of baicalein at a dose of 200 mg/kg using the HPLC-DAD and LC-MS/MS methods. Based on the results, the possible metabolic pathway of baicalein in rat serum was proposed.

Key words: Baicalein, Flavones, Metabolite, LC-MS/MS, HPLC-DAD
