ABSTRACT
A novel chromone, granulosin (1), has been isolated from the bark of Galipea granulosa. The extract of the bark, as well as granulosin (1), exhibited lethality in the brine shrimp test. The structure of granulosin (1) as 2-propyl-7,8-(methylenedioxy)chromone was established via spectroscopic analysis.
