Depsides from the petals of Papaver rhoeas.

摘要: Two new depsides as well the known p-hydroxybenzoic acid and its methyl ester, protocatechuic acid, 2-(4-hydroxyphenyl)-ethanol, 2-(3,4-dihydroxyphenyl)-ethanol flavonoids kaempferol, quercetin, luteolin hypolaetin glycosides 3- O-beta- D-glucopyranosylquercetin (isoquercitrine), D-glucopyranosylkaempferol (astragaline), D-galactopyranosylquercetin (hyperoside) were isolated from methanol extract of petals Papaver rhoeas L. (Papaveraceae). The elucidation their structures was based on NMR spectral evidence.
