Identification of Chemical Components and Blood Components of Tianmaxingnao capsules Based on UPLC-Q/TOF-MS / 世界科学技术-中医药现代化

ABSTRACT

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.
