Nutritional and physicochemical properties of new giant embryo mutant rice (YR23517Acp79, YR) were analyzed. YR exhibited increased total protein (9.3${\pm}$0.3%), lipid (3.7${\pm}$1.1%), amino acid (663.28${\pm}$1.9 mg/g), and mineral contents (Ca=284.0${\pm}$6.2, Mg=1417.5${\pm}$13.6 mg/kg). In YR brown rice four major physicochemicals, including gamma-aminobutyric acid (brown rice= 0.46${\pm}$0.014 mg/g), ${\gamma}$-oryzanol (0.43${\pm}$0.021 mg/g), vitamin $B_1$ (6.42${\pm}$0.3 mg/kg), and tocopherols (alpha= 2.68${\pm}$0.1, beta=0.11${\pm}$0.01, gamma=0.05${\pm}$0.001 mg/100 g) increased in comparison to reported giant embryo (Keunnunbyeo, KB) and normal embryo rice (Ilmibyeo, IB). YR showed higher scavenging activities against 1,1-diphenyl-2-picrylhydrazyl (0.2 g/mL=57.1${\pm}$2.25) and 2,2'-Azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (0.2 g/mL=50.2${\pm}$1.45) radicals but also inhibited lipopolysaccharide-induced nitric oxide production without cytotoxicity. These results indicate YR is a high quality functional rice due to its high nutrition content and antioxidant effects of physicochemicals.
