Fresh and chopped aerial parts of $Oryza$ $sativa$ were extracted in 80% aqueous mehthanol, and the concentrated extract was successively partitioned using $n$-hexane, ethyl acetate (EtOAc), $n$-butanol, and $H_2O$. From the EtOAc fraction, a new flavonolignan (2) and a known flavonolignan, salcolin B (1), were isolated through repeated $SiO_2$ and octadecyl silica gel column chromatography. Based on NMR, mass spectrometer, and IR spectroscopic data, the chemical structure of compound (2) was determined to be tricin-4'-$O$-[erythro-${\beta}$-guaiacyl-(7"-$O$-methyl)-glyceryl] ether, which has thus far never been reported and was named salcolin C (2). Salcolin B (1) and salcolin C (2) dose-dependently inhibited nitric oxide production in RAW 264.7 cells with $IC_{50}$ values of $29.8{\pm}0.6$ and $10.8{\pm}1.0{\mu}m$, respectively, without visible toxic effect.
