Abstract A guided fractionation and characterization of the methanol extract from the leaves of Psidium guajava L. (Myrtaceae) yielded two new benzophenone glycosides, Guajaphenone C (I) and Guajaphenone D (II) together with three known compounds, Guajaphenone A (III), Garcimangosone D (IV) and Guaijaverin (V). Their structures were elucidated by analysis of spectroscopic data including 1D and 2D NMR and electrospray ionization mass spectrometry (ESI-MS). These data were also compared with those reported in the literature.
