title: Three new flavonoid glycosides from Urena lobata.
abstract: Three new flavonoid glycosides, kaempferol-3-O-β-D-apiofuranosyl(1 → 2)-β-D-glucopyranosyl-7-O-α-L-rhamnopyranoside (1), kaempferol-4'-O-β-D-apiofuranosyl-3-O-β-D-glucopyranosyl-7-O-α-l-rhamnopyranoside (2), and 5,6,7,4'-tetrahydroxy-flavone-6-O-β-D-arabinopyranosyl-7-O-α-L-rhamnopyranoside (3), were isolated from the aerial parts of Urena lobata L., along with 10 known compounds (4-13). Their structures were determined based on spectroscopic methods including 1D and 2D NMR spectroscopy as well as HR-ESI-MS.
