Abstract

The objectives of this study were to investigate biological activities such as nitrite scavenging effect of water and methanol fractions obtained from each green juice(Angelica keiskei, kale, carrot) under different pH conditions, and antioxidant vitamin contents in green juice made of green yellow vegetables. The result shows that nitrite scavenging effect of each green juice was 14.0~91.2% in model system. The methanol fraction provided higher effect than the water fraction. The nitrite degradation was the highest at pH 1.2. Nitrite scavenging effect of methanol fraction obtained from kale juice was 91.2% at pH 1.2 which was the highest among tested samples in this experiments. Consequently, extracts of kale juice were shown to provide the greatest functional properties among the vegetables tested. Contents of vitamine E and C in the extracts of kale were higher than the others.
