      Separation of eight selected flavan-3-ols on cellulose thin-layer chromatographic plates
      Irena VOVK*, Breda SIMONOVSKA, H. VUORELA (*Laboratory for Food Chemistry, National Institute of Chemistry, Hajdrihova 19, 1001 Ljubljana, Slovenia)

      J. Chromatogr. A 1077 (2), 188-194 (2005). HPTLC of (+)-catechin (C), (-)-epicatechin (EC), (-)-gallocatechin (GC), (-)-epigallocatechin (EGC), (-)-epicatechin gallate (ECg), (-)-epigallocatechin gallate (EGCg), procyanidin B1, and procyanidin B2 on cellulose prewashed with water (not necessary, when water was used as developing solvent) and dried with a hair dryer, with 1) water; 2) 1-propanol - water 1:4; 3) 1-propanol - water - acetic acid 4:2:1; 4) 1-propanol - water - acetic acid 2:8:1 in horizontal developing chamber (sandwich configuration). Detection with vanillin - H3PO4 reagent. Water enabled the separation of epimers C from EC and GC from EGC, as well as the dimers procyanidin B1 and B2. Additionally C, EGC, B1 and B2 were separated from all the other compounds. The best separation of the five main catechins (EC, GC, EGC, ECg, EGCg) present in green tea extract was achieved using 1-propanol - water - acetic acid 2:8:1. The chromatograms of oak bark extract developed in solvents with higher water content (1-propanol - water 1:4 and 1-propanol - water - acetic acid 2:8:1) showed less bands than chromatograms developed in solvents with higher organic modifier content (e.g. 1-propanol - water - acetic acid 4:2:1). It was proved that such behavior was due to the presence of procyanidins beside the main component catechin.
