Five New Aromatic Glycosides from Carthamus tinctorius

Five new aromatic glycosides, 1–5, named as carthamosides B4–B8, together with three known compounds, 4′-(hydroxyphenacyl)-β-D-glucopyranoside (6), benzyl-O-α-L-rhamnopyranosyl-(16)-β-D-glucopyranoside (7), and 4-(methoxybenzyl)-O-β-D-glucopyranoside (8), have been isolated from the air-dried flower of Carthamus tinctorius. Their structures were identified on the basis of chemical and spectroscopic methods.
