In vitro antioxidant activities of Solanum surattense leaf extract

摘要

Objective:To evaluate the antioxidant activity of alcoholic leaf-extract of Solanum surattense(Solanaceae)(S.surattense).Methods:Leaf extract were tested for in vitro free radical scavenging assays,such as hydroxyl radical and hydrogen peroxide,inhibition of superoxide anion radical and 2,2-diphenyl-1-picryl hvdrazyl radical(DPPH),total antioxidant activity and reducing ability.Further,total phenolic content of S.surattense was analyzed.Results:S.surattense extract effectively scavenged free radicals at all different concentrations and showed its potent antioxidant activity.Further,these effects were in a dose dependent manner.Results were compared to standard antioxidants such as butylated hvdroxytoluene,ascorbic acid andα-tocopherol.Conclusions:S.surattense have strong antioxidant potential.Further the study validates the therapeutic benefits of the Indian system of medicine.
