PRELIMINARY PHYTOCHEMICAL ANALYSIS AND STUDY ON ANTIOXIDANT PROPERTY OF AMARANTHUS CAUDATUS LINN.

Abstract

The present study was carried out for the analysis of dietary antioxidants viz phenolics and flavonoids from the leaves of A.caudatus which is an annual herb and a popular leafy vegetable. The antioxidant potency of the species was analysed in vitro by DPPH reduction test and by reducing power assay. The phenolic content was 2.98 GAE/g while flavonoid content was found to be 5.19 RUE/g. The in vitro antioxidant activities were found to be impressive by both the assay methods. RSA was found to be 41.6mg GAE/g by DPPH test. The IC50 value was found to be 490µl. Moreover preliminary phytochemical analysis showed the presence of saponin, tanin and terpenoid in methanolic extract.
