ANTI-OXIDATIVE AND ANTI-INFLAMMATORYEFFECTS OF ANGELICA DAHURICA EXTRACT.

Angelica dahurica has been well-known to have excellent ability for relieving in flammation. This study was done to evaluate the anti-oxidative and anti-inflammatory activities of A. dahurica extract performed by High Speed Vacuum Low Temperature Extractor. DPPH radical scavenging activity was measured by adjusting the concentration of A. dahurica extract to 10 ~ 60%. This activity was increased in a concentration dependent manner until 40%, but decreased in 60%. The nitrite scavenging activity was measured by adjusting the concentration to 20 and 50%, and pH to 1.2, 3, and 6. As a result, the activity showed better value at 50% than 20%, but presented a trend to increase as the pH value was lower. Therefore, we suggest that anti-oxidant and anti-inflammatory activities of the A. dahurica extract are evaluated to increase in dose dependent manner.
