In this study, fatty acid compositions of mulberry fruit oils havebeen studied. Oil contents of white and black mulberry fruits were 0.82 and 0.97%, respectively. Palmitic, oleic, linoleic and stearic acids were the major fatty acids of both mulberry fruit oils. Fatty acid contents of black mulberry fruit oil were found higher than those of white mulberry fruit oil. Palmitic and linoleic acids were determined as 12.46 %and 13.89% to 58.89% and 63.83% in white and black mulberry fruit oils, respectively. In addition, oleic acid contents of white and black mulberry fruit oils were 11.87% and 12.54%, respectively. So, higher content of linoleic acid of black and white mulberry fruit oils may be evaluated as a good source of essential fatty acid.
