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