Abstract

Beta carotene an antioxidant compound, it is a substance that inhibits the oxidation of other molecules. Free radicals damage cells through oxidation. Eventually, the damage caused by free radicals can cause several chronic illnesses, in our study Beta carotene was extracted by ethanol / dichloro methane (solvents) from the carrots and tomato samples which collected from some markets in ElBeida City (Libya). The Beta carotene contents were measured by using a spectrophotometer. The UV spectrophotometric method which carried in this study gave excellent linearity standard curve (r 2= 0.993) in the concentrations a range of (10 - 80 ppm), the concentrations of extracted Beta carotene ranged from (4.9-72.63 ppm). A compassion between the contents of Beta carotene in fresh and storage vegetables was studied, in addition the comparison between Libyan and Egyptian carrots and tomato samples. The results of compassion not showed wide difference.
