Chromatogram obtained after the injection of 1.0 [micro]L of standard stock solution containing the palmitate esters of methyl (1), methyl stearate (2),
methyl oleate (3), methyl linoleate (4) and methyl linolenate (5).

Five ester compounds, namely
methyl oleate, methyl linoleate, isopropyl myristate, methyl octadecanoate and methyl hexadecanoate except above a repellent response was found against all the three bedbug stages (Table 5).
Chromatographic analysis (Figure 3) showed that biodiesel obtained under optimal conditions indicated in Figure 4 consisted mainly of palmitic acid methyl esters,
methyl oleate, methyl linoleate, methyl linolenate and other methyl esters whose composition range between C16:0 and C22:0.
Reference standard, supelco 10 and 30 (mix of 20% of methyl stearate, methyl palmitate, metyl linoleate, methyl linoleic,
methyl oleate, methyl capric, methyl caprilic, methyl myristate and Methyl Laurate) was purchased from Sigma Aldrich Sdn Bhd for GC analysis.

methyl oleate based polyether polyols as renewable resources," Journal of Polymer Science A, vol.
To estimate the solubility parameters of the methyl esters, a mixture model with the five major components of methyl esters (methyl palmitate, methyl stearate,
methyl oleate, methyl linoleate, and methyl linolenate) was created by using Amorphous Cell.
