Identification of cyclopropyl fatty acids in walnut (Juglans regia L.) oil.
OBJECTIVE
Identification of cyclopropyl fatty acids in walnut oil.


METHODS
GC/MS method was developed for the determination of eight cyclopropyl fatty acids in walnut (Juglans regia) oil.


RESULTS
Monocyclopropane acids: methyl 9-cyclopropyl-nonanoate, 6,7-methylene-, 8,9-methylene-, 9,10-methylene-, 11,12-methylene octadecanoates, and dicyclic acid - methyl 9,10,12,13-dimethylene octadecanoate, tricyclic acid - methyl 9,10,12,13,15,16-trimethylene octadecanoate, and unsaturated - methyl 2-octylcyclopropene-1-octanoate were detected in walnut oil by GC-MS and their mass spectra studied. Four cyclic fatty acids were identified for the fist time in seed oils.


CONCLUSIONS
Eight cyclopropyl fatty acids were detected in the Mediterranean nuts for the first time.
