Abstract

The effect of tissue cultured and tissue culture derived Mentha species viz. Mentha piperita (PPR611), Mentha arvensis (SH) and Mentha spicata (SPR 8) on antioxidant potential using lipid peroxidation model was studied. The extracts prepared were analyzed for total phenols and flavonoids. Tissue cultured derived plants were found to have higher content of total phenols and flavonoids. Furthermore, Mentha spicata (SPR 8) was found to possess higher content of total phenols, however, flavonoid content of tissue cultured samples was more compared to tissue culture derived plants in Mentha arvensis (SH) and Mentha spicata (SPR 8).Tissue cultured plants of all the three species were more potent in lipid peroxidation inhibition model. Tissue cultured derived plants were less effective in preventing lipid peroxidation and inhibition potential decreased with development period in all the three species.

Key words: Flavonoids, lipid peroxidation, Mentha, phenols, tissue culture.
