high resolution nuclear magnetic resonance spectroscopy in studies of Picrotoxanolides of Coriaria. Coryamyrtin

Abstract

Spectral evidence by Protonic Nuclear Magnetic Resonance (400 MAHz and 90 MHz) of the analeptic sesquiterpene lactone coriamyrtin, isolated from the colombian plant Coriaria microphyUn, Poir., is discussed, and analogies are made with the spectra of authentic samples of picrotin and picrotoxinin.
