Prenylated flavones from Artocarpus altilis
Six prenylated flavones, including one new compound, were isolated and identified from the stem bark extracts of Artocarpus altilis. The new prenylated flavone hydroxyartocarpin (1) was characterized as 3-(c,c-dimethylallyl)-6-isopentenyl-5,8,20,40-tetrahydroxy-7-methoxyflavone and the known compou...

| Summary: | Six prenylated flavones, including one new compound, were isolated and identified from the stem bark extracts of Artocarpus altilis. The new prenylated flavone
hydroxyartocarpin (1) was characterized as 3-(c,c-dimethylallyl)-6-isopentenyl-5,8,20,40-tetrahydroxy-7-methoxyflavone and the known compounds were artocarpin (2),
morusin (3), cycloartobiloxanthone (4), cycloartocarpin
A (5) and artoindonesianin V (6). The structures of the
compounds were determined by spectroscopic methods
(IR, MS, 1H-NMR and 13C-NMR) and comparison with
published data for the known compounds. |
