Abstract: This research uses red,pink,yellow and green tomatoes as experimental materials,and adopts spectrophotometer to determine lycopene contents at different tomato maturing periods,and from 3 different parts and calculates tomato lycopene contents by standard curve formula.The result shows that lycopene contents increase gradually along with tomato maturing and reach the tiptop at the late maturing stage.The lycopene contents of tomato variety with red fruit is the highest,that of variety with green fruit is the lowest.The earliest lycopene synthesis is placenta.
