Chromatography of an ethanolic extract of Pycnarrhena manilensis over silica gel afforded phaeanthine-2'α-N-oxide (1) and pycmanilline (2) which were characterized as new bisbenzylisoquinoline alkaloids by a consideration of physicochemical data and the utilization of simple chemical reactions.Phaeanthine-2'α-N-oxide (1) was reduced to phaeanthine (3) while pycmanilline (2), a secobisbenzyliso-quinoline alkaloid, was prepared via oxidation of phaeanthine (3).
