Abstract
The direct resolution of racemic jasmonic acid (JA) and abscisic acid (ABA), as the free acids, into the corresponding enantiomers by high p erformance liquid chromatography on a Nucleodex beta-PM column is repo rted. The resolution factors (R(sJA)=1.38; R(sABA)=1.65) were such tha t the method could be applied to the separation of these racemates on a preparative scale. The racemates of methyl jasmonate and its 12-hydr oxy-derivative could be resolved as their respective methyl esters. Th e pure isomers obtained were characterized using circular dichroism an d optical rotatory dispersion.
