Abstract
|
|
|
|
The antioxidative effect of the extracts from the leaves and fruits of Acer ginnala against free radicals was studied by two different methods using DPPH radical-generating system, and hydroxyl radical-generating system (Cu^(++)/H₂O₂ system) which induces DNA strand breaking. Compared with well known antioxidative plants, green tea, Scutellaria baicalensis, the Acer ginnala extracts showed excellent radical-scavenging activity in DPPH radical-generating system and inhibited effectively hydroxyl radical induced-DNA strand breaking in a concentration-dependent manner in Cu^(++)/H₂O₂ system whereas the green tea extract stimulated the strand breaking at a low concentration. These results suggest that the extracts from the leaves and fruits of Acer ginnala could be good antioxidative agents.
