RESUMEN
15alpha-Hydroxy-21-keto-pristimerine (1), a new nortriterpene quinone methide was isolated from the root bark of Maytenus catingarum along with other well-known related compounds, including pristimerine (2), tingenone, and 20alpha-hydroxy-tingenone. The structure of 1 was determined by means of 1H and 13C NMR spectroscopy, including homonuclear and heteronuclear correlations. Compound 1 showed antibiotic activity against Gram-positive bacteria.
