title: Two new carthamosides from Carthamus oxycantha.
abstract: Two new glycosides, 2-O-methylglucopyranosyl-carthamoside (1) and beta-D-fructofuranosyl carthamoside (2), along with the known compound 3',4',5,7-tetrahydroxyflavanone (3) have been isolated from Carthamus oxyacantha, using recycling preparative HPLC. The structures of these compounds were established by mass spectrometric and extensive spectroscopic analysis.
