Flavonoids from the flowers of Prunus spinosa L.
Eight flavonoids were isolated from the flowers of Prunus spinosa: kaempferol, quercetin, kaempferol 3-O-alpha-L-arabinofuranoside, quercetin 3-O-alpha-L-arabinofuranoside, kaempferol 3-O-alpha-L-ramnopyranoside, kaempferol 7-O-alpha-L-ramnopyranoside, kaempferol 3-O-beta-D-xylopyranoside, kaempferol 3-O-(2''-E-p-coumaroyl)-alpha-L-arabinofuranoside. The last three have been found for the first time in this plant. The structure of the compounds was determined by means of chemical and spectral methods (UV, IR, LSI MS, 1H NMR, 13C NMR).
