Abstract:

Maytenus species are shown to have antitumor activity. Friedelane triterpenoid is found to be one of most active components, especially aromatic friedelane triterpenoid with A ring or A/B rings. In this study, the chemical structures and of and 13C NMR characteristics of friedelane triterpenoids from Maytenus reported in the literature from 1995 to 2013 are summarized and reviewed. The findings are potentially useful for structure elucidation and assignment of the spectroscopic signals of this type of compounds.

Key words: 13C NMR, maytenus, triterpenoids, friedelane, structure
