DETERMINATION OF PHYTOCHEMICALS AND ANTIOXIDANT ACTIVITY OF ACORUS CALAMUS RHIZOME
Acetone extract of Acorus calamus rhizome was assessed for phytochemical components qualitatively and quantitatively and for its antioxidant activity. The results revealed that the rhizome extract contained alkaloids, carbohydrates, flavonoids, tannins, anthocyanins and phenols. Steroids and saponins were absent in the extract. Phenolics, flavonoids and proanthocyanidins were found to be more in Acorus calamus rhizome extract from quantitative analysis followed by total sugars and tannins respectively. Acorus calamus Â rhizome extract showed the concentration dependent reducing power activity, Free radical scavenging potential andÂ inhibition of lipid peroxidation respectively.Key words: Phytochemicals, Antioxidant activity, Lipid peroxidation, Reducing power activity, Acorus calamus rhizome.
