Abstract
Antioxidative and antimicrobial effects of the extracts of Castanea crenata leaf tea, steamed tea and semi-fermented tea were investigated. Antioxidative effects were by measuring the 1,1-diphenyl-2-picrylhydrazyl(DPPH)-radical scavening activity of the extracts. The effects were stronger than that of synthetic antioxidant such as BHT at the same concentration. The
밤나무 잎을 이용해 제조한 불발효 처리한 증제차와 반발효차의 항산화 및 항미생물 효과를 탐색하였다. 각각의 밤잎차 물추출물을 동결건조한 시료를 DPPH-radical scavenging activity를 측정하여 항산화 효과를 검토한 결과, 두 종류의 차 모두 대조구로 사용한 BHT보다 동일농도에서 강한 활성이 나타났으며, 이들의
