Resumen
Eight new dammarane triterpenes were isolated fro Maytenus Macrocarpa. Their structures were determined by means of 1H and 13C NMR spectroscopic studies, including 1H-13C 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.
