白背三七Gynura divaricate是一种民间广泛使用的药食两用植物，具有清热凉血、活血、止血和止痛的功效。目前从白背三七中发现了70余种化合物，主要包括黄酮类、生物碱类、苯丙素类、萜类、甾体类、脑苷脂类等成分。通过查阅近年来国内外发表的文献资料，对白背三七化学成分及代表性成分质谱裂解特征的研究进展进行了综述，以期为白背三七化学成分结构解析的深入研究提供参考。

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.
