I told him about the xanthophyll inventory I had made in my own garden — how it seemed to be everywhere.

Once the chlorophyll disappears, other substances like carotene and xanthophyll — which have been present all along but masked by the green of summertime — begin to show.

To separate the carotin from xanthophyll place the ether solution in a small open dish and evaporate to a small volume.
