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

Abstract

AIM

Identification of cyclopropyl fatty acids in walnut oil.

METHOD

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.
