چکیده انگلیسی
Five unusual C-methylflavonoids lacking B-ring oxygenation (2â²,4â²-dihydroxy-3â²,5â²-dimethyl-6â²-methoxychalcone, 2â²,4â²-dihydroxy-3â²-methyl-6â²-methoxychalcone, 2â²,6â²-dihydroxy-3â²-methyl-4â²-methoxychalcone, 2â²-hydroxy-3â²-methyl-4â²,6â²-dimethoxychalcone and 5,7-dihydroxy-6,8-dimethylflavanone) were found for the first time in Metrosideros excelsa. The flavanone was the major constituent in leaves, whereas 2â²,6â²-dihydroxy-3â²-methyl-4â²-methoxychalcone dominated all other aerial plant parts studied. Other Metrosideros species were investigated for these five flavonoids. C19-C36 aldehydes and C22-C32 alcohols were also identified from the dried seed capsules of M. excelsa.
