Identification of 18:3(n-3) linolenic acid, 18:3(n-6) linolenic acid and 18:2(n-6) linoleic acid in Zimbabwean browses preferred by wild black rhinoceroses (Diceros bicornis) determined by GC-MS analysis

Ten browses preferred by black rhinoceroses (Diceros bicornis) in Zimbabwe were analyzed for the presence of two isomers of linolenic acid [18:3(n-3) and 18:3(n-6)] and 18:2(n-6) linoleic acid using GC-MS analysis. The 18:3(n-3) linolenic acid and 18:2(n-6) linoleic acid were found in varying proportions in all of the browses, while 18:3(n-6) linolenic acid was found in much smaller amounts in only some of the browses.
