Evaluation and Selection of Optimal Solvent and Solvent Combinations in Thin-Layer Chromatography of Flavonoids and of Phenolic Acids of Zizyphus jujuba Mill
A series of simple mathematical techniques for the evaluation of solvents combinations in thin-layer chromatography have been investigated. The clasification has been carried out using the numerical taxonomy techniques and informaion 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 Mill. The most suitable chromatographic systems for the separation end future isolation of flavonoids and phenolic acids from Zizypus Jujuba Mill. are : ethyl acetate:formic acid:acetic acid:water, 100:11:11:27, and ethyl acetate:formic acid:water, 8:1:1.
