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. Their structures were determined by 1D and 2D NMR spectroscopy. This is the first report of chemical constituents from N. aurata var. paraciculata.
