Abstract

ABSTRACT α- and γ-terpinene, as well as α- and β-pinene were separated on silica gel and on silica gel impregnated with various percentages of silver nitrate. It was stated that argentation thin-layer chromatography is an efficient technique for separation of isomeric α- and γ-terpinene as well as α- and β-pinene. The optimal conditions of separation of these compounds were determined. The electrotopological states of carbon atoms forming double bonds explain the separation of the terpenes. Qualitative relationships between physical and chromatographic parameters and topological indices, based on adjacency matrix and distance matrix, were formulated.
