Antioxidant and Biological Activities of Three Morphotypes of Murraya koenigii L. from Uttarakhand

Sivakumar ChV and Meera I

The antioxidant activities of three morphotypes of Murraya koenigii L were evaluated by ABTS and phosphomolybdenum assays along with plant polyphenolic constituents and reference antioxidants. All examined methanolic extracts showed significant activity to scavenge ABTS and hydroxyl free radicals, reducing power, iron chelating ability and total antioxidant capacity in the order: Brown>Dwarf>Regular. Total polyphenol content (111-532 mg/g), flavonoid (0.01-0.09%) contents in dried plant samples was determined spectrophotometrically. The present study indicates the value of Murraya koenigii L as good source of antioxidants especially brown type.
