I'm looking for the Rf's of a couple of pigments in paper chromatography,
using a 90% petroleum ester and 10% acetone solvant. The pigments are:
Chlorophyll a and b, B-Carotene, Xanthophylls and Pheophytin.
I've looked in the Handbook of Cromatography, the Handbook of Chemistry
and Physics, and the Merck Index, but I've found nothing.
Could anyone help me?
