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).
These included Methyl laurate (25), methyl myristate (33) and myristic acid (34), methyl iso-pentadecanoate (37), methyl pentadecylate (40), isopropyl myristate (41), methyl palmitoleate (46), palmitoleic acid (49), methyl palmitate (47) and palmitic acid (51), methyl margarate (52), methyl linoleate
(54), methyl oleate (55), Oleic acid (59), methyl elaidate (56), methyl stearate (58), methyl 9Z,12E-Octadecadienoate (60), methyl arachidonate (63), gondoic acid (64), methyl arachidate (65), methyl erucate (69), methyl behenate (70), and methyl lignocerate (75).
Gas Chromatography analysis showed high percentages of Methyl Stearate, Methyl linoleate
, Methyl Palmitate and Methyloleate.
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.

In combination with detecting the possible products of both fullerenols and [C.sub.60] with radical species generated from methyl linoleate
under autoxidation condition, we propose two antioxidant mechanisms which are dependent on the number of hydroxyl groups.
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.
The scientists compared the formation of conjugated dienes from methyl linoleate
in the presence of antioxidants to the control, which had no antioxidant.
