Abstract

In this study, the antioxidant compounds and antioxidant activities of Geumjong brown rice were measured to evaluate functional properties and to compare with white rice and Chuchung brown rice. The content of polyphenolics, flavonoids and $\gamma$-oryzanol were measured by spectrophometric methods and tocopherol and tocotrienol analyses were carried out by HPLC. ABTS and DPPH radical scavenging activity and reducing power were used to measure antioxidant activity. The extraction yield of Chuchung white rice, Chuchung brown rice, and Geumjong brown rice were 1.5, 2.3, and 3.5%, respectively. The high level of antioxidant activity (69.77 mg TEAC/100 g) and total polyphenolic content (69.1 mg gallic acid equivalents/100 g) were found in Geumjong brown rice, whereas the reducing power of Geumjong brown rice was lower than that of Chuchung brown rice.

본 연구에서는 도정되지 않은 현미상태의 금종쌀(Geumjong brown rice) methanol 추출물의 항산화 성분과 항산화활성을 측정하여 새로운 품종의 기능적 가치를 평가하고자 하였다. 이와 함께 백미(Chuchung white rice) 및 현미(Chuchung brown rice)와의 항산화 성분과 항산화력을 비교 분석하고자 하였다. 항산화 성분으로는 polyphenol, flavonoid, vitamin E와 $\gamma$-oryzanol을 측정하였으며 항산화력은 ABTS와 DPPH 라디칼 제거능 및 환원력을 측정하였다. 백미 및 현미, 금종쌀은 각각 1.5, 2.3, 그리고 3.5%의 추출수율을 나타냈다. 실험결과, 금종쌀은 높은 항산화 활성(69.77 mg TEAC/100 g)과 polyphenol함량(69.1 mg gallic acid equivalents/100 g)을 나타냈다. 반면에 환원력에 있어서는 현미(Chuchung brown rice)보다 낮게 측정되었다.
