Popis: From the methylene chloride extract of Ehretia ovalifolia leaves, a new flavone derivative named ovalifolin [3-(3-methyl-1-butenyl)-6-methoxy-5,7,4'-trihydroxy flavone] has been isolated and identified together with the known flavone aglycones apigenin, luteolin and the highly methoxylated flavanol araneosol. The structures of these metabolites have been established on the basis of chemical, chromatographic and spectral methods.
