AccuTOF TM with DART TM
Detection of Lycopene in Tomato Skin
Tomatoes are rich in lycopene, a hydrocarbon
antioxidant that is the source of the red coloring in
ripe tomatoes. The potential benefits of
nutritional antioxidants such as lycopene have
received a great deal of attention in the popular
media.
A piece of tomato skin was placed in front of
the DART and the positive-ion mass spectrum
was recorded. Peaks were quickly observed at
the expected exact masses for lycopene and
[M+H]+ (C40H57+, m/z 537.4460) and phytoene
[M+H]+ (C40H65+, m/z 545.5086).
