Erucic acid was dominant in the grape seed
oil (43.17%). This is in contrast to what was obtained in an
Egyptian grown grape seed oil[15] in which linoleic acid
constituted more than 50% of the total fatty acid while oleic
acid was the second major fatty acid reported. Meanwhile,
oleic acid was not detected in the grape seed oil in this
present study. Water melon seed oil contains 61.11% linoleic
acid and 77.19% total unsaturated fatty acid which is in
agreement with previously reported data[16]. Linoleic acid is
an essential fatty acid that must be obtained through diet.
Preliminary research has found evidence that 毩-linolenic
acid is related to a lower risk of cardiovascular disease[17].
Grape seed oil is the only oil solid at room temperature
which suggested its possible usefulness in production of
specialized liquid soap and shampoo. The lime seed oil
is golden yellow oil with the highest yield (24.79%). The
relatively high oil content of the lime seed indicated that its
