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).
