Lycopene is a pigment principally responsible for the characteristic deep-red color of ripe tomato fruits and tomato products.It, as a natural source of antioxidants, has attracted attentions due to its biological and physicochemical properties.In this study tomato paste prepared from tomato cultivated in Dezfoul (Khozestan) was dehydrated with methanol, then lycopene was extracted from the residue with methanol-carbon tetrachloride mixture.Pure lycopene was obtained by crystallization of crude product from benzene twice by addition of boiling methanol.
