Abyssinone-Ⅴ, 4'-hydroxy-6,3',5'-triprenylisoflavonone, abyssinone-Ⅵ and abyssinone-Ⅳ were all isolated from the genus erythrina. This study completed the first total synthesis of four natural prenylated flavanoids by using simple and facile approaches. The result of their in vitro antibacterial tests indicated that all of them displayed moderate bacteriostatic activities. The compounds abyssinone-Ⅳ and abyssinone-Ⅴ showed remarkable antibacterial activities. The structures of all new compounds have been confirmed by HRMS, 1H NMR and 13C NMR spectra.

Key words: prenylated flavanoid, (±)-abyssinone-Ⅵ, (±)-abyssinone-Ⅳ, (±)-abyssinone-Ⅴ, 4'-hydroxy-6,3',5'-triprenyli-soflavonone, total synthesis, antibacterial activity
