Coumarins from eriostemon spicatus

Coumarins from eriostemon spicatus

Journal of Natural Products 55(5): 685-687

Eight coumarins have been isolated from the aerial parts of Eriostemon spicatus (Rutaceae). Six were characterized as the known compounds scopoletin, dracunculin, heraclenin, deoxybruceol, ramosin [1], and anisocoumarin F [2]. 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 [3] (+)-7-(3-methylbut-2-enyloxy)-8-(4-hydroxy-3-methylbut-2-enyl) coumarin [4] on the basis of spectroscopic analysis.
