THREE HIGHLY OXYGENATED FLAVONE GLUCURONIDES IN LEAVES OF SPINACIA OLERACEA

Article abstract of DOI:10.1016/S0031-9422(00)84967-5

Droplet counter-current chromatographic separation and subsequent TLC demonstrated the existence of at least 14 phenolics in the leaves of Spinacia oleracea.Three have now been isolated and identified, respectively, as the 4'-glucuronides of 5,7,4'-trihydroxy-3,6,3'-trimethoxyflavone (jaceidin), 5,3',4'-trihydroxy-3-methoxy-6:7-methylenedioxyflavone and 5,4'-dihydroxy-3,3'-dimethoxy-6:7-methylenedioxyflavone.Key Word Index- Spinacia oleracea; Chenopodiaceae; spinach; jaceidin; 4'-glucuronide; 5,3',4'-trihydroxy-3-methoxy-6:7-methylenedioxyflavone 4'-glucuronide; 5,4'-dihydroxy-3,3'-dimethoxy-6:7-methylenedioxyflavone 4'-glucuronide; 1H NMR; 13C NMR; FABMS.
