Besides rutin, quercetin 3-rhamnoside and kaempferol 3-rhamnosyl (1-<6) galactoside, a new flavonol glycoside, quercetin 3-glucosyl(1->4)galactoside, and 1,6,8-trihydroxy-1-methyl anthraquinone (emodine) have been characterized from leaves of Rumex chalepensis.The structures were established on the basis of Rf values, acid hydrolysis to aglycone and sugar and UV, EI and FAB-mass-spectra, 1H NMR, 12C DEPT NMR, NOE difference measurements, 1H-H-COSY and 1H-13C COSY spectral data.
