Five pyranocoumarins, avicennol, cis-avicennol, dipetalolactone, avicennol methyl ether, and cis-avicennol methyl ether have been isolated from the aerial parts of Asterolasia drummondii. Examination of the aerial parts of Asterolasia squamuligera has shown it to contain 3-(3-hydroxy-3-methyl-trans-but-1enyl)-7-methoxycoumarin [6], which is novel. Asterolasia drummondii, in addition to containing coumarins, has afforded the furoquinoline alkaloids, maculosidine and gamma-fagarine.
