In Vitro Anti Oxidant Study of Ethanolic Extract of Coldenia procumbens Linn

An investigation has been carried out to evaluate the in vitro antioxidant activity of ethanolic extract of Coldenia procumbens Linn by Diphenyl-1-picryl hydrazyl method (DPPH) and Nitric oxide radical scavenging inhibition activity method. Coldenia procumbens Linn has been widely used for a number of medicinal purposes especially in Siddha medicine. However, the information available on the pharmacological activity of the plant is very limited. Hence, it was proposed to carry out a preliminary in vitro analysis of the anti oxidant activity of the plant, which gave promising results. The standards used were ascorbic acid and rutin. This is the first report of the antioxidant activity of the plant.
