Abstract: To assay the contents of lycopene in several samples. The effects of different pretreatments on assay were studied. The linear range of the method is 0.180~5.796μg/ml, with LD=0.0059μg/ml. Analysis showed that the methanol treatment is favorable for assay so that within 24 hours, the lycopene solution is stable. The results thas showed that this method is favorable for assaying the contents of lycopene in tomato and tomato products.

Key words: lycopene, spectrophotometric method
