Four new glycosides, namely 3β-norpinan-2-one 3-O-β-d-apiofuranosyl-(1→6)-β-d-glucopyranoside (1), (6Z)-3-hydroxymethyl-7-methylocta-1,6-dien-3-ol 8-O-β-d-glucopyranoside (2), (6E)-3-hydroxymethyl-7-methylocta-1,6-dien-3-ol 8-O-β-d-gluco-pyranoside (3), and 7-[(β-d-apiofuranosyl-(1→6)-β-d-glucopyranosyl)oxymethy]-8,8-dimethyl-4,8-dihydrobenzo[1,4]thiazine-3,5-dione (4), were isolated from the fruits of Xanthium sibiricum Patr together with three known compounds, xanthiside (5), adenosine (6), and 2,3-dihydroxy-1-(4-hydroxy-3-methoxyphenyl)-propan-1-one (7). The structures of the new compounds were determined on the basis of detailed spectroscopic analyses. View Full-Text
