%X Maculosidine has the structure I, previously suggested. By degradation it is converted to 6,8-dimethoxy-3-ethyl-4-hydroxy-2-quinolone, identified by synthesis.   Maculosine, which has formula C17H1706N and the typical ultraviolet spectrum of a furoquinoline, is oxidized by periodate to a substance which is degraded to the known 3-ethyl-4-hydroxy-6,7-methylenedioxy-2-quinolone. This evidence leads to the assignment of IV as its structure.
