Abstract Eight new dammarane triterpenes were isolated from Maytenus Macrocarpa . Their structures were determined by means of 1 H and 13 C NMR spectroscopic studies, including 1 H- 13 C heteronuclear correlation (HETCOR), long range correlation with inverse detection (HMBC), and chemical evidence. This is the first time that dammarane triterpenes have been isolated from Celastraceae.
