N H Lee1, Y J Xu, S H Goh.   

Abstract

Two new 5-oxonoraporphines, 1 and 2, together with three known compounds, ouregidione, 3-methoxycepharadione B, and isoelemicin, have been isolated from the bark of Mitrephora cf. maingayi. Structures of 1 and 2 were determined to be 1,2,3-trimethoxy-5-oxonoraporphine and 1,2-dimethoxy-3-hydroxy-5-oxonoraporphine on the basis of NMR and MS studies.
