In vitro anti oxidant activity of methanol extract of Clerodendrum infortunatum Linn

The antioxidant potency of methanolic extract Clerodendrum infortunatum Linn. (MECI), which are widely used in the Indian indigenous system of medicine for different purposes, was studied. The antioxidant potential was evaluated using different established in vitro antioxidant tests viz. determination of total amount of polyphenolics compounds, DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging, nitric oxide scavenging, superoxide anion radical scavenging, hydroxyl radical scavenging and reductive power assay. It was found that MECI contain a high amount of polyphenolics and possesses significant free radical scavenging activity in all the assay. The higher activity was may be due to presence of richest amount of polyphenolics and flavonoids in it.
