Abstract

Tomatoes (Lycopersicum esculentum) are horticulture plants frequently cultivated in Indonesia. Lycopene is one of tomatoes largest chemical content in tomatoes. This research had been able to isolate lycopene with extraction method on 65 °C temperature using hexane and methanol antisolvents. Isolation procedure in thisresearch was modification from previous research. Sample in this research were dry tomatoes powder. Research result showed that hexane solvent yielded lycopene level of 3.10 mg/100 g tomatoes powder. Functional group analysis using Fourier TransformInfraRed (FT-IR) spectroscopy detected C = C group at wavelength 1674,91 cm-1 and 1639,65 cm-1, aliphatic CH (streching) was indicated by the appearance of a sharpabsorption peak at number wave 2853,12 cm-1, CH (CH3). Indicates absorption at wave number 1378,71 cm-1. The sharp peak at the wave number 2924,16 cm-1 shows thepresence of C-H alkene (streching), and C-H alkene (bending) at the wave number 1498,86 cm-1.
