Phytochemical profiling of the stem bark of Betula utilis from different geographical regions of India using UHPLC-ESI-MS/MS

Abstract

A simple, rapid, sensitive, and reliable ultra-high-performance liquid chromatography-hybrid linear ion trap triple quadrupole mass spectrometry method was developed and validated for simultaneous determination of 10 bioactive compounds in stem bark of Betula utilis grown in high altitude of Himalaya, India. The objective of the study is to develop and validate ultra-high-performance liquid chromatography-hybrid linear ion trap triple quadrupole mass spectrometry for investigation of geographical variations of triterpenoids, phenolics, and flavonoids contents in stem bark of B. utilis. The validated method was successfully applied to investigate geographical variations of triterpenoids, phenolics, and flavonoids in stem bark of B. utilis. The contents of betulinic acid and oleanolic acid were detected higher among selected analytes. The present variation study reveals great importance for the application and overall assessment of B. utilis.
