从密蒙花属(Mitrephora cf,maingrayi)树皮中分得两个新的5-氧代去甲阿朴啡(1和2),以及三个已知化合物ouregidione、3-methoxycepharadione B和isoelemicin。化合物1和2的结构经NMR和MS分析确定为1,2,3-三甲氧基-5-氧代诺拉啡和1,2-二甲氧基-3-羟基-5-氧代诺拉啡。
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, maingrayi. 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.
