The hydrolysis of anthraquinone glycosides on TLC plates is described and the influence
of different conditions is investigated. This method in connection with two dimensional
separation of the aglycones formed by hydrolysis allows all glycosides to be evaluated.
Densitometric curves are given to follow up the several stages of hydrolysis and to
show the spectrum of glycosides of Frangula bark.
Anthraquinone Glycosides - Hydrolysis - Reaction Conditions - two dim. TLC - Densitometry.
