Abstract: A comparative investigation was carried out to evaluate and analyze the effects of four solvents and three extraction methods on the extraction of lycopene from autumn olive berry. The optimal process for lab-scale extraction of lycopene from autumn olive berry was as follows: Autumn olive berry was extracted repeatedly 4 times using methyl acetate as extraction solvent at a material/liquid ratio of 1:40 with grinding under light-free conditions, and then the extract was vacuum concentrated at 57.8 ℃. The resulting yield of lycopene was 34.81 mg/100 g of fruit. Meanwhile, the extraction solvent could be recycled. The content of lycopene in the concentrated extract ranged from 6.4 mg/100mL to 7.5 mg/100 mL. This study can offer an experimental reference for future industrial production.
