azafluorenone alkaloid 5,8-dimethoxy-7-hydroxy-1-methyl-4-azafluoren-9-one and the megastigman (–)-(5R*, 6S*)-megastigman-3-one-10,7-olide were isolated from aerial parts of Unonopsis lindmanii (Annonaceae), along with the known compounds (3S*, 5S*, 8R*)-3,5-dihydroxymegastigma-6,7-dien-9-one (grasshopper ketone), N-trans-feruloyltyramine, (–)-anonaine, (–)-asimilobine, liriodenine and (–)-syringaresinol
氮杂芴酮生物碱5,8-二甲氧基-7-羟基-1-甲基-4-氮杂芴酮-9-和megastigman(–)-(5R *,6S *)-megastigman-3-one-10,7-olide分离自菩提属(Unonopsis lindmanii(Annonaceae)的地上部分,连同已知化合物(3S *,5S *,8R *)-3,5-二羟基巨头-6,7-dien-9-one(草hopper酮),N-反式-Feruloyltyramine,(-)-氨基酸,(-)-阿斯米洛宾,鹅绒den碱和(-)-丁香脂醇。这是对番荔枝科中巨角柱菌的首次描述。根据光谱数据阐明了化合物的结构。
