^aValues are relative percent (%) of the transesterifiable lipids calculated by the use of in situ transesterification and are presented relative to the area under the peak from GC/MS analysis of the transesterifiable lipid portion ranging from retention time of 5–15 min
^bAbout 34 % of total fatty acids were mono-unsaturated and 5.6 % of total fatty acids are poly-unsaturated
^cBy difference
