Flavonol triglycosides from the leaves of Hammada scoparia (POMEL) ILJIN.
A new flavonol triglycoside, isorhamnetin 3-O-beta-D-xylopyranosyl-(1""-->3)-alpha-L-rhamnopyranosyl-(1'''-->6")-beta-D-galactopyranoside, has been isolated from the leaves of Hammada scoparia together with two known compounds, isorhamnetin 3-O-beta-D-apiofuranosyl-(1'''-->2")[alpha-L-rhamnopyranosyl-(1""-->6")]-beta-D-galactopyranoside and isorhamnetin 3-O-alpha-L-rhamnopyranosyl-(1'''-->2")[alpha-L-rhamnopyranosyl-(1""-->6")]-beta-D-galactopyranoside. The structures were determined by spectroscopic methods.
