Fatty acid analysis of algal oil
GC-MS analysis of algal oil shows the presence of
4 major fatty acids and some minor compounds
shown in Fig. 3. The major components in GC-MS
are methyl palmitate (C16:0), at retention time
29.93 min, methyl oleate at retention time 28.21 min
(C18:1), methyl linoleate (C18:2) at 29.70 min and
methyl linolenate (C18:3) at 27.62 min. Other studies
show that Chlorella species contains majority of
short-chain fatty acids (C14–C18) which are main
components of biodiesel
