Yuka Isobe Megumi Morioka Norihiko Terahara Takashi Komiya Miyo Narita The antioxidative activity of the crude pigment extracted from akamajiri-kuromai colored rice was measured by its suppressive activity toward the oxidation of linoleic acid, DPPH radical-scavenging activity, and OH radicalscavenging activity. The pigment extracted from akamajiri-kuromai exhibited higher antioxidative activity than the pigment extracted from red rice and black rice. The pigment of akamajiri-kuromai contained two components: the one fractionated from butanol was identified as Cy 3-Glc by HPLC and <sup>1</sup>H-NMR analyses, and the one fractionated from ethyl acetate seemed to be tannin.
