Abstract:

In color pigment made of wheat, but the research and development of wheat ErBenJi clear color - 2 - bitter hydrazine base of free radicals are rarely studied.Studies of the pigment color grain spectroscopic and antioxidant properties in common wheat, through and ascorbic acid and determination by DPPH black wheat, blue, violet wheat grain of wheat, red, white, wheat grain of wheat pigment antioxidant, scavenging free radicals, the ability of the wheat with the increase of the concentration of the pigment, its antioxidant ability of free radicals, correspondingly improved. All sorts of color pigment crude extractings wheat with concentration-response relationship of antioxidant activity, and its free radicals ability than common wheat, but less than ascorbic acid, including black wheat pigment scavenging free radicals, the strongest blue and purple wheat grain of wheat scavenging free radicals, white wheat ability and red wheat clear ability weak but most common wheat than. This explains the darker skins of wheat, the stronger ability of free radicals. Common wheat, black, blue wheat grain of wheat, red, purple wheat grain of wheat, white wheat and Vc DPPH 50% clear of free radicals EC50 concentration (effective) respectively188.27, 54.26, 76.22, 94.05, 126.24, 110.04, 0.139. Its free radical scavenging capacity AE respectively by 0.53×10-2, 1.84×10-2, 1.31×10-2, 1.06×10-2, 0.79×10-2, 0.91×10-2, 719×10-2. Such as wheat color skin of a crude extractings pigment its ability of free radicals, which are better for further research, development and utilization of wheat color pigment theoretical basis.
