Hyptis suaveolens (L) poit commonly known as Vilayati tulsi, belongs to the family Lamiaceae. Production of reactive oxygen species (ROS) causes various diseases and cellular anomalies in human beings. Antioxidants inhibit generation of reactive species, or scavenge them, or raise the levels of endogenous antioxidant defenses. In this study the antioxidant activity of various extract of Hyptis suaveolens (L) poit leaves were evaluated using Total Antioxidant Activity Method, Nitric oxide radical scavenging activity, DPPH Scavenging method, H2O2 scavenging activity, Reducing power assay. The result obtained in the present study indicated that the ethanolic extract of Hyptis suaveolens (L) poit could be a potential source of natural antioxidant. | A study on antioxidant activity of Hyptis suaveolens L poit
