While in n-butanol fractionthe n-hexadecanoic acid was present in high concentration with 13.72% followed by ester of phtalic acid, cis-7, cis-11-hexadecandien-1-yl acetate, octadecanoic acid
, and oxacycloheptadec-8-ene-2-one, (8Z) with relative abundance of 7.66 5.99, 5.88 and 5.11% respectively.
[USPRwire, Sun Nov 11 2018] Stearic acid is also called octadecanoic acid
, which is basically one of the most common long-chain fatty acids.
Pentadecanoic acid, 14-methyl-, M-hexanedecanoic acid, z-[13, 14-epoxy]tetradec-11-en-1-ol acetate, oleic acid, 9octadecenoic acid[z]-, 2-hydroxy-1-[hydroxyl methyl], heptanoic acid, docosyl ester, octadecanoic acid
, 7-hydroxy-,6-octadecenoic acid[z]-, and 8-octadecenoic acid  were also found.
 which detected by GCMS the presence of stearic acid or octadecanoic acid
as the majority fatty acids in the biosurfactant.
(2012)  evaluated the antibacterial activities of ethyl acetate extract, aurantiamide acetate 9, docosanoic acid 65, n-hexadecanoic acid 66, octadecanoic acid
67, oleic acid 68, and lupeol 86 isolated from the stem bark of A.
Heneicosane, nonadecane, pentacosane, cyclohexadecane, tricosene, docosane, eicosane compounds from hydrocarbons; palmitic acid, ethyl oleate, octadecanoic acid
, decanedioic acid compounds from aliphatic acids and their esters; cinnamic acid, ferulic acid from cinnamic acids and their esters; pinostrobin chalcone, pinocembrin, chrysin compounds from flavonoids; [beta]-eudesmol, guaiol, 2-methoxy-4-vinylphenol, l-limonene, a-muurolene, farnesol, Y-terpinene, [beta]-myrcene, a-pinene compounds from alcohols and terpenes; benzoic acid, propanoic acid, 3,4-dimethoxycinnamic acid compounds from aromatic acids; 2-nonadeca-none, 2-pentadecanone compounds from ketones were determined in the propolis sample by GC-MS.
The study identified organic acids such as dodecanoic, hexadecanoic, tetradecanoic, octadecanoic acid
and acetic acid in the defatted vegetable milk product (DPSY).
Therefore, the lower level of 9-Octadecenoic acid (Z) observed for the treatments with supplemental fatty acids could be attributed to the lower transfer of this fatty acid from blood to muscle and/or a decrease in its synthesis from Octadecanoic acid
by the stearoyl-CoA desaturase.
(E)-2-octenoic acid, oleic acid, phenyl acetic acid, hexadecanoic acid and octadecanoic acid
were found to elicit a repellent response at all the four different concentrations (Table 3).
