One new feruloyl sucrose ester, 3-feruloyl-4′,6′-diacetyl sucrose (1), along with five known feruloyl sucrose esters, 3,6-diferuloyl-3′,6′-diacetyl sucrose (2), smilaside A (3), 3,6-diferuloyl-6′-acetyl sucrose (4), 3-feruloyl-6′-acetyl sucrose (5), and 3,6-diferuloyl sucrose (6), was isolated from Oryza sativa roots. The chemical structures of the compounds were determined by spectroscopic data analysis. The six isolated feruloyl sucrose esters were evaluated for their inhibitory effect on mushroom tyrosinase in vitro.
