Abstract
Objectivenbsp Coleus aromaticus CA is a medicinal plant used popularly in India against various diseases. The present study was undertaken to investigate the in vitro antioxidant activity of the proteins isolated from Coleus aromaticus plant leaves. MethodsProteins from the coleus aromaticus water extract was isolated by ammonium sulphate protein precipitation method. In vitro antioxidant studies were carried out by 22-diphenyl-1picrylhydrazyl DPPH Nitric oxide and superoxide radical scavenging methods compared with standard antioxidant like Butylated Hydroxy Anisole BHA and Ascorbic acid. ResultsThe percentage inhibition of radical scavenging activity increased with increase in concentrations of crude protein of Coleus aromaticus extract and is comparable with standard antioxidants BHA and ascorbic acid. Conclusion The results of this study concluded that the Coleus aromaticus proteins possess significant antioxidant activity when compared to standard antioxidants.
