摘　　要：以黑香米、黑小米、黑大豆、黑绿豆、黑苦荞、黑小麦、黑花生、黑玉米、黑芝麻、黑红薯为原料,研究了10种样品提取液的抗氧化特性.研究表明,黑香米、黑苦荞、黑红薯提取液IC50值较小,表现出较好的清除[DPPH.]特性;较长的诱导时间则说明黑苦荞、黑芝麻、黑红薯提取液有较好的延缓猪油氧化的能力.With the black rice, black millet, black bean, black mung bean, black buckwheat, black wheat, black peanut, black corn, black sesame and black sweet potato as materials, the antioxidant activities of 10 kinds of extracts were studied. Results showed that melanin extracts from black rice, black buckwheat and black sweet potato had the stronger capability of scavenging [ DPPH · ] radical because of their lower IC50. The longer induction time of melanin extracts from black buckwheat, black sesame and black sweet potato revealed that they had the stronger ability of retarding lord to be oxidized.
