초록

본 연구는 염생 식물이라는 특성으로 인해 갯벌이 발달한 우리나라에서 쉽게 접할 수 있는 칠면초에 대한 분석과 항산화활성을 검토하고자 이루어졌다. 일반성분 분석 결과, 수분을 제외하고 탄수화물, 단백질, 회분의 함량이 10.75%, 8.3%, 7.6%로 많이 측정되었다. 무기질 중에서는 나트륨이 5.4%로 측정되어 회분의 대부분이 나트륨임을 알 수 있었다. 중금속함량 측정 결과, 납, 카드뮴, 비소, 수은은 각각 건물 기준 0.86 ppm, 0.04 ppm, 0.39 ppm, 0.01 ppm을 나타내어 식품으로서 기준치에 적합하였다. 70% 에탄올로 칠면초를 추출하여 항산화력을 알아본 결과, 총 페놀 함량과 총 플라보노이드 함량은 18.77 mg/g, 2.69 mg/g을 보여주었다. Hydroxyl radical 소거능, hydrogen peroxide 소거능, xanthine oxidase 소거능등을 측정하여 합성항산화제인 BHA와 비교한 결과, BHA의 30~50% 가량의 활성을 보여주었다.

This study was conducted in order to analyze the ingredients and antioxidant activity of Suaeda japonica (turkey), which is abundantly present in Korea where mud flats are well formed due to the characteristics of halophytes. In the analysis of general composition, contents of carbohydrates, proteins, ash, and moisture were 10.7%, 8.3%, 7.6%, and 72.5% respectively. Among minerals, sodium was measured as 5.4%, which means that most ash was made of sodium. Heavy metal contents of lead, cadmium, arsenic, and mercury were 0.86 ppm, 0.04 ppm, 0.39 ppm, and 0.01 ppm, meaning Suaeda japonica satisfied standard food values. The 70% ethanol extract from Suaeda japonica was evaluated for its free radical scavenging activity and compared with a commercial antioxidant, BHA (butylated hydroxyanisole). As a result, the scavenging activities of hydroxyl radical, hydrogen peroxide, and xanthine oxidase of the extracts were equivalent to 30~50% of that of BHA.
