The needles ofLarix sibirica Ledb. have yielded two new flavonoid glycosides, for which the structures of 4′,5,5′,7-tetrahydroxy-3′-methoxyflavonol 3-O-β-D-glucopyranoside (laricitrin 3-glucoside) and 4′,5,7-trihydroxy-3′,5′-dimethoxyflavonol 3-O-[O-β-D-glucopyranosyl-(1→6)-α-L-rhamnoside] (syringetin 3-rutinoside) have been established.
