Does anyone remember the identity of the blue-green pigment
that is extracted from spinach with acetone and runs down with
or below the xanthophylls when you separate pigments by TLC?
(No, not chlorophyll....)

When we do this experiment, we get 4 bands: a blue green that is
Chlorophyll a, an olive green that is chlorophyll b, a pale yellow
that is xanthophyll, and an orange-yellow that is carotene. (These
are separated with 95 parts ether and 5 parts acetone, but extracted
with acetone.)
