Eight coumarins have been isolated from the aerial parts of Eriostemon spicatus (Rutaceae). Six were characterized as the known compounds scopletin, dracunculin, heraclenin, deoxybruceol, ramosin 111, and anisocoumarin F 121. The other two appear to be novel and have been identified as (+)-7-(3-methylbut-2-enyloxy)-8-(2-hydroxy-3-methylbut-3-enyl) coumarin 131 and (+)-7-(3-methylbut-2-enyloxy)-8-(4-hydroxy-3-methylbut-2 enyl) coumarin 141 on the his of spectroscopic analysis. Western Australia is a rich source of plants in the Rutaceae, few of which have been examined for their secondary metabolites. As part of a survey of the chemistry of species of the genus Eriostemon (1,2), carried out in collaboration with the Western Australian Herbarium, we have recently examined the aerial parts of Eriostemon spicatus A. Rich. This slender woody perennial, which grows only to a height of 60 cm (3), has not previously been studied.
