THE DIFFERENCE IN LYCOPENE AND β-CAROTENE CONTENT IN CITRUS PARADISI FRUIT AND ROSA CANINA DRIED FRUIT

Abstract

Citrus paradisi fruit and Rosa canina dried fruit are rich sources of vitamin C. The aim of this work was to highlight their content of lycopene and β- carotene in order to contribute to their chemical profile. For that purpose the conventional extraction method was applied with solvent mixture consisting of 250 ml hexane, 125 ml of acetone, 125 ml of ethanol (2:1:1, v/v/v), and 0.05 % (w/v) butylated hydroxytoluene (BHT). UV-Vis spectrophotometric method was performed and for final calculation of concentrations was used Lambert-Beer’s law. Obtained results for content of lycopene and β-carotene in Citrus paradisi fruit and Rosa canina dried fruit are 2.27 and 2.34, that is 2.28 and 7.25 mg per 100 g/fruit weight (FW), respectively. The obtained results are recommending these two nutrients in everyday diet.
