Abstract (EN):
The separation of the diastereoisomers of cinnamoyl derivatives have been studied by thin-layer (TLC) and high performance liquid chromatography (HPLC). TLC separations on two different layers and with two different solvent systems are described. HPLC separation was carried out on a reversed-phase column (Lichrosorb RP-8, 5 mu m) using an isocratic elution [acetonitrile : water-acetic acid (95 : 5)]. The series of compounds includes the cis/trans isomers of ethyl esters of caffeic, ferulic and isoferulic acids.
