Two new flavonol glycosides, quercetin 3-O-(2__-O-_-D-glucopyranosyl)-_-L-arabinofuranoside and kaempferol 3-O-(2__-O-E-p-coumaroyl)-_-L-arabinofuranoside-7-O- _-L-rhamnopyranoside, were isolated from the leaves of Prunus spinosa L. The known compounds, kaempferol, quercetin, and their 3-arabinofuranosides, kaempferol 7-rhamnopyranoside, kaempferol 3,7-dirhamnopyranoside, and kaempferol 3-arabinofuranoside- 7-rhamnopyranoside were also identified. Structural elucidation was performed by means of chemical methods and UV, IR, LSI MS, 1D and 2D NMR spectroscopy.
