        This study investigated the functional substances, including phenolics, tocopherol compounds in rice (Onnuri, Nampyeong, Dongjin, Deuraechan, Hopum, Iksan-515, Iksan-526) that were cultivated in Iksan region. Specially, Iksan-515 and Iksan-526 were produced resveratrol rice. Resveratrol is health-beneficial compound with strong antioxidant activity. Iksan-515 and Iksan-526 were contained resveratrol compound while, other rice varieties did not showed resveratrol. The total phenolic compounds showed similar concentrations in 7 rice varieties. Especially, Iksan-526 revealed 273.3 ㎍ g-1 and Iksan-515 was 264.8 ㎍ g-1. In this study, we analyzed vitamin E contents of 7 varieties of rice. The total tocopherols revealed 418.3 ㎍ g-1 in Iksan-526, 401.2 ㎍ g-1 in Iksan-515 and 413.3 ㎍ g-1 in Hopum. We determined 4 tocopherols (α-, β-, γ-, δ-) and 4 tocotrienols (α-, β-, γ-, δ-). Among the all samples, β-tocotrienol showed higher average concentrations (101.3 ㎍ g-1) than other compounds and, γ-tocotrienol revealed second higher concentration (94.5 ㎍ g-1). On the other hand, δ-tocopherol was not detected in all rice samples.
