High resolution NMR for purity determination of cyclopropenoid concentrates
Journal Of The American Oil Chemists' SocietyPeer ReviewedBoudreaux G. J. +21972Journals
High resolution nuclear magnetic resonance is proposed as a method for assaying the cyclopropenoid concentration of methyl sterculate and methyl malvalate concentrates. Spectra obtained on a 220 MHz instrument are analyzed and compared with that obtained on a 60 MHz instrument. Calculation of cyclopropene concentration based on methoxy protons and cyclopropene protons is discussed.
