Nonvolatiles of commercial lime and grapefruit oils separated by high-speed countercurrent chromatography
The nonvolatile fractions of cold-pressed peel oils of Key and Persian lime as well as grapefruit were separated by high-speed countercurrent chromatography (HS-CCC). In addition to the isolation of the main coumarins, psoralens and polymethoxyflavones, a
Key Word Index-Cachrys sicula; Umbelliferae; furocoumarins; (-)-sprengelianin; ferulol esters. (-)-Sprengelianin, (-)-prantschimgin and other minor coumarins were isolated from the roots and/or the umbels of Cachrys sicula.The roots also afforded the monoterpene hydroxyaldehyde ferulol esterified to angelic, tiglic and senecioic acids.The (-)-enantiomer of sprengelianin (2'S) had not been reported previously.The coumarins saxalin and pabulenol and the aromatic aldehyde 2,3,4-trimethylbenzaldehyde were also identified but these substances are presumably artefacts.
