Male Carica papaya flowers, one of natural materials, have many pharmacology activities including anticancer. We report herein the isolation and structural elucidation of known compounds. Eight flavonoids, kaempferol ( 1 ), kaempferol 3‐ O ‐ α ‐ L ‐rhamnopyranoside ( 2 ), kaempferol 3‐ O ‐ β ‐ D ‐glucopyranoside ( 3 ), kaempferol 3‐ O ‐ α ‐ L ‐arabinopyranoside ( 4 ), quercetin ( 5 ), quercitrin ( 6 ), quercetin 3‐ O ‐ β ‐ D ‐galactopyranoside ( 7 ) and myricitrin ( 8 ) were isolated from the ethyl acetate extract of male Carica papaya flowers. Their structures were determined by NMR, MS spectra and by comparing with the reported data.
