Abstract
From the bark of Flindersia maculosa Lindl. were isolated the known alkaloids, kokusaginine and flindersiamine, the new alkaloids, maculine and maculosine, the known coumarin, collinin, and a triterpene, flindissol. Maculine appears to be a methylenedioxydiotamnine. The leaves contained kokusaginine, the new alkaloid, maculosidine, and the new flavone, flindulatin. The structure 6,s-dimethoxydictamnine is proposed for maculosidine, and flindulatin is shown by degradation and synthesis to be 5-hydroxy-3,4',7,8-tetramethoxyflavone (3,4',7,8-tetramethylherbacetin).Keywords
