Product feature application of the Resveratrol
Figure: Reducing Power of Resveratrol
Figure shows the reducing power of resveratrol. The reducing power of resveratrol increased with increasing concentration. Based on a comparison of the absorbance at 700 nm, the reducing power of resveratrol at a concentration of 120ug/ml was similar to that of BHT at 480ug/ml. This indicates that resveratrol was electron donors and could also react with free radicals, converting them to more stable products and terminate the radical chain reaction. Also, 480ug/ml resveratrol is the best concentration which exhibits the most reducing power. The reducing power of resveratrol and BHT decreased in the order of resveratrol>BHT.

Figure: Strong Anti-oxidant
