Isolation of Lycopene from Papaya and Study of its Antimicrobial Activity

The extraction of lycopene was done from Papaya. The identification of isolated lycopene was done by using various tests like TLC, U. V spectroscopy, IR. TLC analysis reported the Rf value of lycopene to be 0.6200. The U. V analysis results reported the wavelength which was 443.2nm. The IR analysis was done which results were as follows. Cycloalkane observed value was 2920.04, aromatic compounds observed value was found to be 1564.80, alkane observed value was found to be 1046.66. Antimicrobial activity of lycopene was then studied by using gram-positive bacteria (bacillus substills) the antimicrobial activity of lycopene was found to be 25.
