Flavonoids of Guiera senegalensis J. F. GMEL.- Thin-layer Chromatography and Numerical Methods

摘要

The efficiency of seven thin-layer chromatographic systems for separating nine flavonoids isolated from Guiera senegalensis J. F. GMEL. (Combretaceae) was investigated. For this purpose, three mathematical techniques were applied. The first technique was the calculation of the information content derived from Shannon's equa- tion for each chromatographic system. In the second technique, the discriminating power of the systems was measured individually and in various combinations.
