The conditions used for TLC and HPTLC analysis of catechins have been optimized. Chemically modified stationary phases (HPTLC CN, HPTLC NH2, and HPTLC RP-18W) were used for qualitative examination of polyphenol fractions obtained by an SPE–RP 18 method from Uncaria tomentosa bark. Although the best separation of catechin from epicatechin was achieved on octadecyl plates, silica gel plates are good enough for preliminary investigations of crude plant extracts.
