Abstract
Supercritical carbon dioxide (SC-CO2) extraction of xanthones from mangosteen pericarp was carried out
at the following operational condition: pressure of 20, 25, and 30 MPa and temperature of 40, 50, and
60 �C. A total xanthone yield of 7.56% (w/w) was obtained at 30 MPa and 60 �C. A rapid and sensitive high
performance liquid chromatography/electron spray ionization mass spectrometry (HPLC/ESI-MS) method
was developed for the quantification of xanthones with mobile phase containing acetonitrile:methanol
and a weak organic acid. The SC-CO2 operating conditions impacted enrichment of xanthones when compared
to ethanol extract by Soxtec method. The structures of xanthones isolated were established on the
basis of nuclear magnetic resonance (NMR) and mass spectroscopic studies.
