Abstract

To compare varietal differences in Rubus coreanus Miq. (Rosaceae), we evaluated antioxidant activity and the contents of functional substances. In this study, five new cultivars selected as superior berries in yield and weight of fruit, R. coreanus (Jungkeuam 1, 2, 3, 4, and 5), and one foreign berry, R. fructicosus were used. The contents of the major anthocyanin, cyanidin-3-glucoside (C3G) in berries and antioxidant capacity including, free radical scavenging activity and reducing power were measured. The contents of total phenol and vitamin C were also investigated. Among 5 cultivars and one foreign berry, Jungkeuam 1 had the richest C3G and high levels in vitamin C. DPPH radical scavenging activity of berries was ranged from 46.58 up to 78.55%.

품종별에 따른 복분자 딸기 열매의 항산화 활성 및 기능성 성분 함량을 비교 분석하였다. 우수한 품종으로 개발한 정금 1, 2, 3, 4, 5호(10년생)와 도입종 블랙베리(Rubus fructicosus)를 사용하였다. DPPH법을 이용한 항산화 활성은 2 mg/㎖ 농도에서 46.58에서 78.55% 범위에 있었으며, 이 중 정금 1호의 항산화 활성이 우수하였다. 총 페놀 함량과 비타민 C 함량 및 안토시아닌 중 베리류의 대표성분인 cyanidin 3-glucoside의 함량을 측정한 결과 정금 1호가 다른 품종에 비해 우수한 결과를 나타내었다.
