Fatty Acid Composition and Antioxidative Activity in Waxy Corn (Zea mays L.) $F_1's$

찰옥수수 $F_1$의 지방산 조성과 항산화 활성

This study was carried out to obtain basic information for breeding materials on the improvement of waxy corn (Zea mays L.). The percents of palmitic, stearic, oleic, linoleic and unsaturated fatty acids in 310 $F_1's$ analyzed were $14.6\;{\pm}\;2.5%,\;2.5\;{\pm}\;1.0%,\;24.8\;{\pm}\;4.2%,\;55.6\;{\pm}\;5.4%\;and\;81.8\;{\pm}\;3.1%$, respectively. The mean value of antioxidative ability was $22.8\;{\pm}\;5.9%$. The average contents of tocopherols, phenolic compounds and carotenoids were $36.2\;{\pm}\;11.5\;{\mu}g/mL,\;120.3\;{\pm}\;27.7\;{\mu}g/mL\;and\;0.4\;{\pm}\;0.6\;{\mu}g/mL$, respectively. The level of oleic acid was significantly correlated with the level of linoleic acid. The electron donating ability was significantly correlated with the level of phenolic compounds and tocopherols but not with the content of carotenoids

우리나라 찰옥수수의 품질을 향상시키는 성분육종의 기초자료를 제공하고자, 310개 $F_1$의 지방산 조성과 항산화 활성, 페놀화합물, tocopherols, carotenoids의 함량을 분석한 결과는 다음과 같다. Palmitic acid와 stearic acid, linoleic acid, 불포화지방산은 각각 $14.6{\pm}2.5%,\;2.5{\pm}1.0%,\;24.8{\pm}4.2%,\;55.6{\pm}5.4%,\;81.8{\pm}3.1%$였고, 항산화 활성과 페놀화합물, tocopherols, carotenoids의 함량은 각각 $22.8{\pm}5.9%,\;36.2{\pm}11.5\;{\mu}g/mL,\;120.3{\pm}27.7\;{\mu}g/mL,\;0.4{\pm}0.6\;{\mu}g/mL$였다. Linoleic acid와 oleic acid 간에는 고도의 부의 상관관계가 있었다. 항산화활성은 페놀화합물과 tocopherols 함량과는 고도의 상관관계가 있었으나, carotenoids의 함량과는 유의성이 없었다
