UPLC-Q/TOF-MS法快速分析天麻醒脑胶囊的化学成分及血中移行成分

Identification of Chemical Components and Blood Components of Tianmaxingnao capsules Based on UPLC-Q/TOF-MS

目的采用超高效液相色谱-四极杆-飞行时间质谱联用技术对天麻醒脑胶囊化学物质组和入血成分进行辨识研究,初步阐明其可能的药效物质基础。方法本研究建立了一种超高效液相色谱-四级杆-飞行时间质谱联用方法鉴别天麻醒脑胶囊的化学成分。采集并分析大鼠给药后的血浆样品,探究天麻醒脑胶囊在大鼠体内暴露成分。结果通过UPLC-Q/TOF-MS分析,共鉴别出天麻醒脑胶囊组方中195种化学成分,分为苯酚类、三萜皂苷类、苯乙醇苷类、环烯醚萜类、脂质类和苯丙素类等,包含了天麻、地龙、肉苁蓉、熟地黄、远志、石菖蒲的特征性成分。在给药大鼠血浆样品中鉴定出37个天麻醒脑胶囊原型成分和3个代谢产物。结论该方法简便高效、灵敏准确,初步阐明了天麻醒脑胶囊的药效物质基础,对天麻醒脑胶囊及其入血成分进行了较全面地研究。本研究为天麻醒脑胶囊的药效物质基础的阐明提供了依据,对揭示天麻醒脑胶囊的药理作用机制具有一定参考意义。

Objective The chemical composition and blood components of Tianmaxingnao capsules were discovered and examined using UPLC-Q/TOF-MS,and the possible pharmacological substance basis was preliminarily elucidated.Methods An UPLC-Q/TOF-MS method was developed in this study to determine the chemical composition of Tianma Xingnao capsules.After administration of Tianmaxingnao capsules,gather and examine rat plasma samples to investigate the exposed components of Tianmaxingnao capsules in rats.Results A total of 195 chemical components were identified in Tianmaxingnao capsules,including phenols,triterpenoid saponins,phenylethanol glycosides,cyclic ether terpenes,lipids,and phenylpropanoids.These components include those that are typical of Gastrodia elata Bl,Pheretima,Cistanche deserticola Ma,Rehmannia glutinosa,Polygala hybrida DC,and Acorus tatarinowii.Rat plasma samples were used to identify 37 prototype components and 3 metabolites of Tianmaxingnao capsules after they were administered.Conclusion This approach is easy to use,effective,sensitive,and precise.It may be used to investigate Tianmaxingnao capsules and the components that reach the bloodstream in detail,as well as to provide a first understanding of the pharmacological basis of the capsules.This study serves as a foundation for clarifying the pharmacological basis of Tianmaxingnao capsules and holds some reference value in exposing the pharmacological mechanism of the product.
