Sažetak

A series of simple mathematical techniques for the evaluation of
solvents and solvent combinations in thin-layer chromatography
have been investigated. The classification has been carried out using
the numerical taxonomy techniques and information content
derived from Shannon's equation. The methods have been applied
to an RF data set of flavonoids and phenolic acids identified in the
methanolic extract of Zizyphus jujuba MilI. The most suitable chromatographic systems for the separation and future isolation of flavonoids and phenolic acids from Zizyphus jujuba Mill. are : ethyl
acetate : formic acid : acetic acid : water, 100 : 11 : 11 : 27, and
ethyl acetate : formic acid : water, 8 : 1 : 1.
