title: Two chromones from Peperomia vulcanica.
abstract: TWO CHROMONES: 5-hydroxy-2-(14'-(E)-nonadecenyl) chromone (1) and 5-hydroxy-2-[12'-(3",4"-methylenedioxyphenyl)dodecanyl] chromone (2), together with six known compounds have been isolated from Peperomia vulcanica Baker & C. H. Wright (Piperaceae). Their structures were determined by spectroscopic analysis including 2D NMR techniques.
