Effect of Particle Size on Antioxidant Activity and Cytotoxicity in Purple Corn Seed Powder

This study was carried out to evaluate anti-oxidant and anticancer activity of crudes extracts from colored corn (Zea mays. L.) among particle size with different pul-verizing methods (pin mill and ultra fine pulverizer). In cytotoxicity test using extracts from the flours grounded by pin mill and ultra fine pulverizer respectively, it showed that A-549 was the highest anticancer activity among in vitro using 4 cancer cell line types (Hep-G2, A-549, HCT-116 and MCF-7). Assessing the antioxidant activities of crude extracted from different pulverizing methods was measured by trolox equivalent antioxidant capacity (TEAC) and ferric reducing antioxidant power (FRAP). Higher scanvening activity against free radical was observed in the crude extracted from small particle size flours of colored corn than in those of the big particle size.
