| Abstract:
Eight compounds were isolated from Maytenus floribunda (Reiss) Celastraceae. The leaves of the plant yielded the steroids:  -sitosterol and -sitosterol-D-glucoside.
The bark wood yielded the polyol: dulcitol; the steroids: -sitosterol and -sitosterol-D-glucoside; the flavonoids: 4'–O-methyl-(-)-epigallocatechin and proanthocyanidin A; and the pentacyclic triterpenes: friedelin, friedelinol and 28-hydroxy-3-oxo-friedelane.
The substances were identified by spectral analysis (UV, IR, 1H and 13C NMR) and melting point. | |
