Abstract
|
|
|
|
The composites(PM-A~PM-I) of 9 groups containing 7 kinds of hot water extracted medicinal plants were produced and evaluated its antioxidative activity. Each medicinal plants used these composites were analyzed in primer research that its antioxidative activity was high. In the composites of medicinal plant, electron donating ability was higher than 70% in all sample. PM-D, PM-E and PM-F were significantly higher than others. Reducing power have similar tendency to electron donating ability. PM-D was the strongest in hydroxyl radical scavenging activity, followed by PM-E. In linoleic acid system, antioxidative activity of all sample was showed more than 50%, except PM-A. Especially PM-E and PM-F have significantly higher activity. Nitrite scavenging effect was significantly increased by PM-D, PM-E and PM-F added to Inula Japonica Thunberg. In these results, we suggested that higher antioxidative activity of PM-D, PM-E and PM-F may be responsible for the contents of phenolic compounds present in Inula Japonica Thunberg. And thought to be enhanced by the synergy effect of the water extracted medicinal plants in the composite.
