Abstract:

Maize hybrid for grain, ‘Kangilok’ was developed in 2005 by Gangwon Agricultural Research and Extension Services in republic
of Korea and registered in 2007. Since 2007, Kangilok has been supplied every year in republic of Korea. The objective of this
study was to investigate worth of 4 parts of Kangilok for functional foods. The 4 parts are kernels (K), dehulled kernels (DK), skin
of kernels (SK) and Cobs (C) of Kangilok. It was focused on anti-oxidative, anti-inflammatory activities of 60% ethanol (in 1% citric
acid) extract from 4 parts of Kangilok. We evaluate radical scavenging activity on DPPH and ABTS radicals for anti-oxidative effect
and on the production of nitric oxide in RAW 264.7 cell for anti-inflammatory effect. DPPH radical scavenging activity (0.1 mg/ml)
was 93.5~72.6 % and ABTS radical scavenging activity (0.1 mg/ml) was 48.2~79.9%. No production (0.1 mg/ml) was 9.5~6.0 uM.
These results suggest that the 4 parts of Kangilok may be useful for functional materials such as anti-oxidative, anti-inflammatory
agent.
