is the yellow (xanthophyll) more soluble than chlorophyll?
Also, i have performed a thin plate chromatography of tomatoe paste and  i was
wondering about the pigments that appeared. Results illustrated that at the top
there was orange which is most likely  the carotene  and at the very bottom
there was a dark yellow.  does this mean all the lighter colours and bands seen
in between had green at some point? they were not very are they
even present between the orange and the yellow?
