The best separation of catechin and epicatechin was achieved by multiple gradient development with increasing concentrations of acetonitrile (from 20 to 22%) in the water - formic acid mixture. UV detection at 282 and 500 nm (after derivatization with vanillin-phosphoric acid) for estimation of catechin content.

Quantification by absorbance measurement at 340 nm for (1), 286 nm for (2) and 265 nm for (3). The hRf values for (1), (2) and (3) were 34, 40 and 56, respectively. Linearity was in the range of 100-800 ng/zone for (1) and (2) and 50-400 ng/zone for (3). LOD and LOQ were 6 and 17 ng/zone for (1), 4 and 13 ng/zone for (2) and 4 and 13 ng/zone for (3), respectively. Recoveries were in the range of 98.1-99.3 % for (1), 98.4-99.5 % for (2) and 98.0-99.1 % for (3). Intermediate/interday/intra-day precision was below 2 % (n=6).
J. Sep. Sci. 37, 2797-2804 (2014). HPTLC of six flavonoids ((1) rutin, (2) luteolin-7-o-glucoside, (3) chamaemeloside, (4) apigenin-7-o-glucoside, (5) luteolin, (6) apigenin) and one coumarin, (7) umbelliferone, from chamomile plant samples and dietary supplements on amino silica gel with dichloromethane - acetonitrile - ethylformate - glacial acetic acid formic acid 44:10:12:5:5.
