The vials were agitated for 5 minutes and left at room temperature to allow phase separation. Therefore the proposed method was used for the routine analysis of the pharmaceutical dosage forms. <> Authors . The lycopene content accurately and reproducibly with a correlation coefficient of 0.9996. The method utilizes Supelcosil LC-18 column (150 × 4.6 mm), 3 μm particle size and a mobile phase consisting of acetonitrile, methanol and tetrahydrofuran (70:25:5, % v/v) at a flow rate of 1.0 mL/min. stream HPLC/UV Analysis of the Lycopene Materials and Methods Lycopene was analysed using reversed-phase high- Materials performance liquid chromatography using isocratic elution and UV detection at 472 nm (Waters, Zellik, Belgium). They occur in tomato fruits and various tomato products in amounts of 2.62−629.00 (lycopene) and 0.23−2.83 mg/100 g (β-carotene). Most of carotenoids from tomato-based products have been found among those determined in human plasma revealing the biological and nutritional importance of such products as good sources of food constituents with functional properties (3–5). !2SQY1��L VBɗ���j�K d�^����nV��e{9�01����Ȣo_��z��v %�8�zQ� G.
