Abstract
The C-13 nuclear magnetic resonance spectra of Vernonia galamensis see d oil and of epoxidized palm super olein, soybean oil and linseed oil have been recorded and interpreted. The chemical shifts of the major s ignals are assigned and semi-quantitative results are derived. The spe ctroscopic procedure provides a useful method of analyzing oils that c ontain epoxy acids. The epoxide function differs from a double bond in its influence on the chemical shifts of nearby carbon atoms.
