From the aqueous ethanol extract (AE) of Carthamus tinctorius seeds, a new
acacetin diglycoside has been isolated and identified as acacetin 7-O-beta-
D-apiofuranosyl-(1'''--> 6 " instead of 6')-O-beta-D-glucopyranoside togeth
er with previously isolated kaempferol 7-O-beta-D-glucopyranoside, acacetin
7-O-alpha-L-rhamnopyranoside and acacetin. The structures of these metabol
ites have been established on the basis of chemical, chromatographic and sp
ectral methods.
