Thin Layer Chromatography of Steroid Saponins and their Derivatives.

Abstract

Thin layer chromatography on silica gel-gypsum was applied to steroid saponins and their derivatives such as peracetates and permethylates. The method has many advantages over paper chromatography in speed, sensitivity, and, above all, in resolving power of the closely related high molecular weight saponins and of the slightly polar derivatives.
