Description Pudina extract (Mentha spicata Linn.) used as flavoring in culinary preparation throughout the plains of India was examined for its DNA damage protecting activity and antioxidant potential. n-Butanol soluble fraction (PE) derived from methanol extract of Mentha spicata Linn. at 10 mu g/ml exhibited significant protecting activity against DNA strand scission by (OH)-O-. on pBluescript 11 SK(-) DNA. IC50 concentration of PE to scavenge DPPH., ABTS(.+) and superoxide radical was 7.47, 4.05 and 57.80 mu g/ml, respectively. Inhibition of lipid peroxidation induced with 25 mM FeSO4 On rat liver homogenate as lipid source was noted at 500 mu g/ml of PE with Antioxidant Index of 63.43%. Total polyphenol content of one-milligram pudina extract was equivalent to 500 mu g of gallic acid. Therefore, this potential bioactivity of pudina extract was associated with its high polyphenolic content. (c) 2005 Elsevier Ltd. All rights reserved.
