Oxalis debilis var. corymbosa (dc.) lourteig and oxalis corniculata l: a comparative study of nutraceutical properties

The present study was designed to make a comparative study between the antioxidant activity and nutraceutical properties of Oxalis debilis and Oxalis corniculata. The antioxidant activity was evaluated by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radicals and the IC50 value of methanolic extract of Oxalis corniculata and Oxalis debilis were found 25.82 ± 0.68 and 73.67 ± 0.91 µg/ml respectively. Among the nutraceutical properties carbohydrate, protein, crude fibre, total phenolic content and ascorbic acid were investigated. The result shows that Oxalis debilis have higher nutraceutical value than Oxalis corniculata with the exception of crude fiber content which was found to be higher in case of O. corniculata. The results revealed that these two plants can be used as dietary supplement as well as therapeutic agent as they would exert several beneficial effects by virtue of their antioxidant activity.
