Abstract:
From the aerial parts of Ochradenus baccatus, the new flavonoids, quercetin 3-O-beta-glucosyl(1----2)-alpha-rhamnoside-7-O-alpha-rhamnoside and quercetin 3-O-p-coumaryl(1----6)-beta-glucosyl(1----6)-beta-glucoside-7-O-alpha rhamnoside were isolated. The known quercetin glycosides, quercetin 3-gentiobioside, isoquercitrin, quercitrin, together with the known kaempferol glycosides, astragalin and afzelin, were also characterized. The structures were established by conventional methods of analysis and confirmed by spectral analysis.
