This study was performed to provide basic data of ‘Kangilok’. The objective of this study was to investigate worth of 4 parts of maize hybrid for grain, ‘Kangilok’ for functional foods. The 4 parts are kernels, dehulled kernels, skin of kernels and cobs of ‘Kangilok’. We evaluated moisture, crude ash, crude lipid, crude protein, crude fiber and mineral content of ‘Kangilok’. The moisture of kernels, dehulled kernels, skin of kernels and cobs of ‘Kangilok’ were 11.27%, 12.40%, 9.45%, 8.85% and the crude ash were 1.26%, 0.73%, 3.19%, 1.42%. Each of the crude lipid were 3.84%, 2.69%, 8.59%, 0.46% and the crude protein were 9.40%, 9.96%, 12.10%, 2.80%. The crude fiber of kernels, dehulled kernels, skin of kernels and cobs of ‘Kangilok’ were 2.24%, 0.92%, 7.07%, and 33.51%. Among the mineral contents, Ca and K content of cobs were highest by 4.84 mg/100 g, 114.33 mg/100 g and Fe, Mn contents of skin of kernels were highest by 5.30 mg/100 g, 2.64 mg/100 g. Mg content of kernels was the highest by 27.42 mg/100 g. P content of kernels, dehulled kernels, skin of kernels and cobs were 1.20%, 0.96%, 2.41%, and 0.19%. It was performed test on anti-oxidative, anti-inflammatory activities of 60% ethanol extract from 4 parts of Kangilok. The anti-oxidative effect was measured by DPPH and ABTS radical scavenging activity. As a results, DPPH radical scavenging activity (10 mg/mL) was 72.59%~93.05% and ABTS radical scavenging activity (10 mg/mL) was 48.17%~79.88%. The anti-inflammatory effect was measured by ability to inhibit production nitric oxide (NO) in RAW264.7 cell. As a result, all the extract of 4 parts were showed significantly inhibitory effect on NO production. Carotenoid contents quantified by using HPLC. β-Carotene of carotenoid was not analyzed in all the sample. Lutein and zeaxantin ware analyzed in kernels and skin of kernels.
