Allelochemicals from Stauranthus perforatus, a Rutaceous tree of the Yucatan Peninsula, Mexico

Pyranocoumarins, furanocoumarins, lignans, a sesquiterpene, and an alkylamide were isolated from Stauranthus perforatus (Rutaceae). Phytotoxicity is one of the more pronounced bioactivities shown by the extracts and isolates, in particular by xanthyletin and chalepensin.
