Two New Flavonol Glycosides from the Aerial Parts of Lotus lalambensis Growing in Saudi Arabia

Phytochemical study of the aerial parts of Lotus lalambensis Schweinf resulted in the isolation and identification of two new flavonol glycosides; kaempferol 3-O-(5"-acetyl)-apioside-7-O-α-L-rhamnopyranoside (1) and kaempferol 3-O-α-[β-D-xylosyl-(1""→2")-L-rhamnopyranoside]-7-O-α...

Summary:Phytochemical study of the aerial parts of Lotus lalambensis Schweinf resulted in the isolation and identification of two new flavonol glycosides; kaempferol 3-O-(5"-acetyl)-apioside-7-O-α-L-rhamnopyranoside (1) and kaempferol 3-O-α-[β-D-xylosyl-(1""→2")-L-rhamnopyranoside]-7-O-α-L-rhamnopyranoside (2). Structures were determined utilizing different physical, chemical, spectroscopic data including 2D-NMR experiments and HRFABMS.
