Research progress on chemical constituents of Gynura divaricate and mass spectrometry-based fragmentation rules of representative components

Abstract

Gynura divaricate was widely used as an herb medicine or food in the folk, which had the efficacy of clearing heat and cooling blood, activating blood, hemostasis and relieving pain. In previous studies, more than 70 compounds have been reported, including flavonoids, alkaloids, phenylpropanoids, terpenoids, steroids and cerebrosides. Research progress on chemical constituents of G. divaricate and mass spectrometry-based fragmentation rules of representative components were reviewed in this paper by consulting literatures published at home and abroad in recent years, in order to provide information for further structural research of G. divaricate.
