Glutathione S-transferase(GST) and antioxidant activities of Acer mono and Acer okamotoanum were compared after being extracted at 20MPa and 60℃ for 15 minutes with water. All the extracts from Acer mono and Acer okamotoanum showed relatively high scavenging activities.
Specifically, bark of Acer okamotoanum extract showed the highest activity as 97.4%. Both of Acer mono and Acer okamotoanum showd high ability on nitrite scavenging, but decreasing tendency according to increasing of pH. Bark of Acer okamotoanum also had high ability as
53.4% of scavenging ability at pH 1.2. On SOD-like test, the wood of Acer okamotoanum was shown the highest activity as 46.2% at 1.0 mg/㎖ concentration. Generally, the bark of both Acer mono and Acer okamotoanum had higher activity than other parts, but interestingly, the
wood of Acer okamotoanum showed the highest activity on SOD-like test. GST activation of bark of Acer okamotoanum was observed as 197.3% in adding 1.0 mg/㎖. From these results, the extracts from high pressure extraction have relatively good antioxidant and GST activities,
compared to those from other conventional extraction processes. It also concludes that the bark of Acer okamotoanum had better biological activities than other parts of Acer mono.
