Effect of natansnin on DPPH* radical scavenging activity

Compound	% inhibition of radical scavenging activity
Butylated hydroxy toluene (BHT)	60.6
Natansnin	63.6

Natansnin was screened for antioxidant activity using 2, 2'-di phenyl-1-picrylhydrazyl (DPPH) radical scavenging method. A known antioxidant butylated hydroxy toluene (BHT) was used as standard. The activity expressed as % inhibition of radical scavenging activity. While natansnin showed 60.6% of radical scavenging activity, BHT showed 63.6%.
