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
It was noted that manool, E- nerolidol, germacrene D, benzyl benzoate, palmitic acid, methyl palmitate
d-cadinene and anthranilic acid, were found as the major components in essential oil.
Objective: To determine the effects of methyl palmitate
on murine model of chronic asthma.
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.
From the components of the transesterified plant oils methyl palmitate
is the most effective ester in achieving reduction of hydrocarbons and particulates in exhaust emissions.
Concentration dependence of methyl palmitate
isotope ratios by electron impact ionization gas chromatography/ mass spectrometry.
Some of the fats filtered out, such as methyl palmitate
and methyl stearate, tend to have the best combustion properties, however.
In SCAQMD Method 313, compounds that elute before Methyl Palmitate
are defined as VOCs while compounds that elute after Methyl Palmitate
are not considered VOCs.
But the winner was an ester called methyl palmitate
, the team reports in the Aug.
As a result, certain semi-volatile compounds that would not be considered VOCs under Method 24 may be considered VOCs under Method 313, since Method 313 relies on methyl palmitate
as a VOC "marker.
The following chemicals were used in this work: esters reference standards including methyl esters of methyl heptadecanuate, methyl myristate, methyl laurate, methyl palmitate
, methyl stearate, methyl oleate, methyl linoleate, 1,2,4-butanetriol (5 mL, concentration 1 mg/mL in pyridine) assigned as internal standard 1, and internal standard 2 of tricaprin (5 mL, concentration 1 mg/mL in pyridine) were purchased from Supelco (USA).
