H. Haberlein et al., PIPER METHYSTICUM - ENANTIOMERIC SEPARATION OF KAVAPYRONES BY HIGH-PERFORMANCE LIQUID-CHROMATOGRAPHY, Planta medica, 63(1), 1997, pp. 63-65
A simultaneous separation of the enantiomers of kawain, dihydrokawain,
methysticin, and dihydromethysticin as well as the achiral dienolides
yangonin and demethoxyyangonin was carried out on a ChiraSpher(R) NT
column. This HPLC method can be used for the investigation of the enan
tiomeric purity of plant material and herbal medicines. The influence
of temperature and flow rate are discussed in respect to the chromatog
raphic resolution of the enantiomers. All tested enolide racemates can
be preparatively separated on ChiraSpher(R) NT.
