This research has determined qualitatively and quantitatively the fatty acids composition of white (Morus
alba) and black (Morus nigra) fruits grown in Spain, in 2013 and 2014. Four clones of each species were
studied. Fourteen fatty acids were identified and quantified in mulberry fruits. The most abundant fatty
acids were linoleic (C18:2), palmitic (C16:0), oleic (C18:1), and stearic (C18:0) acids in both species. The
main fatty acid in all clones was linoleic (C18:2), that ranged from 69.66% (MN2) to 78.02% (MA1) of the
total fatty acid content; consequently Spanish mulberry fruits were found to be rich in linoleic acid,
which is an essential fatty acid. The fatty acid composition of mulberries highlights the nutritional and
health benefits of their consumption.
