Abstract
Supercritical fluid extraction of kava lactones from Piper methysticum Forst, herb is described here, The extraction was performed with supe rcritical carbon dioxide alone and supercritical carbon dioxide modifi ed with 15% ethanol, and the extracts were analyzed by gas chromatogra phy/mass spectrometry, Seven lactones including: 7,8-dihydrokavain; ka vain; 5,6-dehydrokavain; 5,6,7,8-tetrahydroyangonin; dihydromethystici n; yangonin; and methysticin were the major constituents in the SFE ex tract.
