Abstract
Two new 5-oxonoraporphines, 1 and 2, together with three known compounds, o uregidione, 3-methoxycepharadione B, and isoelemicin, have been isolated fr om the bark of Mitrephora cf, maingrayi. Structures of 1 and 2 were determi ned to be 1,2,3-trimethoxy-5-oxonoraporphine and 1,2-dimethoxy-3-hydroxy-5- oxonoraporphine on the basis of NMR and MS studies.
