Polyoxygenated flavonoids from Eugenia edulis.
Leaves of Eugenia edulis contain the new polyoxygenated flavonoid derivatives, gossypetin-3,8-dimethyl ether-5-O-beta-glucoside; gossypetin-3,5-dimethyl ether, and myricetin-3,5,3'-trimethyl ether. In addition, ten known polyphenolics were also isolated and identified. All structures were established on the basis of chemical and spectral evidence, including ESI-MS and 13C NMR.
