This paper is dedicated to Professor Yoshinori Asakawa for his 65 th birthday. Three new oxygenated noraporphine alkaloids were isolated from the bark of the Chinese tree Neolitsea aurata var. paraciculata. The new compounds, (+)-11-methoxynorcassythicine, (+)-11-methoxynorneolitsine, (+)-11-methoxynorboldine, were isolated along with eight known aporphine alkaloids, hernovine, ovigerine, N-methylovigerine, 10-O-methylhernovine, lindcarpine, N,O-dimethylhernovine, laurolitsine and nandigerine.
