Chlorophyll can be extracted from spinach leaves and appears green. Lycopene can be extracted from tomato and appears red. What are the approximate λmax values for these pigments?
Homework Answers
In case of chlorophyll extracted from spinach leaves, while measuring the absorption maximum you will get two significant peak at around 450-470 nm and another one is around 650 - 660 nm. Normally here chlorophyll is a mixture of chlorophyll a and chl b. This peak is the mixture of chla and chl b.
And for the lycopene extracted from the tomato, we will have absorption maximum at around 470 -475 nm.

Pre lab
Introduction Your instructor has prepared an extract of chloroplast pigments from fresh green grass or fresh spinach. A blender was used to rupture the cells, and the pigments were then extracted with acetone, an organic solvent. Work- ing with one other student, begin this exercise by separating the pigments extracted using paper chromatography. To do this, you will apply the pig- ment extract to a cylinder of chromatographic paper. You will then place the ylinder in a jar...
