Further flavonoids from the flowers of Prunus spinosa L.
Further seven flavonoids were isolated from the flowers of Prunus spinosa L.: quercetin 3-O-alpha-L-arabinopyranoside, 3-O-alpha-L-rhamnopyranoside, 3-O-beta-D-xylo-pyranoside, and 3-O-beta-glucopyranoside, kaempferol 3,7-di-O-alpha-L-rhamnopyranoside, kaempferol and quercetin 3-O-(4"-beta-D-glucopyranosyl)-alpha-L-rhamnopyranosides. Four of them have been found for the first time in this plant. Structural elucidation was performed by means of chemical and spectral methods (UV, LSI MS, 1D and 2D NMR).
