is known to exhibit strong antimicrobial and anti-inflammatory activity [5, 37].
Valley Cottage, NY, December 17, 2015 --(PR.com)-- Palmitic acid is also known as hexadecanoic acid
in the International Union of Pure and Applied Chemistrynomenclature.
, an aromatic component which had been linked to the flavour of pineapple fruits (Liu et al., 2011) was predominant in all the samples analysed.
In result of GC-MS analysis, 3-methyl-2-buten-l-ol (26.56%), hexadecanoic acid
(16.06%), dodecanoic acid (9.99%), linalool (5.63%) and octadecadienoic acid (4.10%) were the most abundant volatiles detected in the distillate (Zhao et al., 2006).
(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).
The major phytochemical compounds among them were 4-(4-ethoxyphenyl) but-3-en-2-one, an aliphatic acid (peak area: 56.90%) (Figure 4(c)), trehalose, sucrose (peak area: 11.49%) (Figure 4(d)), hexadecanoic acid
, methyl ester, a linoleic acid ester (peak area: 6.52%), and 9octadecenoic acid (Z)-, methyl ester, another linoleic acid ester (peak area: 6.76%).
Its active ingredients including phytol and its derivative, hexadecanoic acid
, 1-hexadecene, and pheophorbide related compounds have shown some promising results as anticancer when whole extracts have been used.
The fatty acid profile showed a very simple pattern consisting of Hexadecanoic acid
, Tetradecanoic acid, Octadecanoic acid, 9-Hexadecenoic acid, 9-Octadecenoic acid, 9,12-Octadienoic acid (Table 3).

For example, all concentrations of hexadecanoic acid
(C16) tested were totally ineffective against spores of all test fungi, while pentanoic and hexanoic acid were effective against all test fungi but only at a concentration of [10.sup.3] ppm.
The methyl ester standards (all above 99% purity) for gas chromatography (GC) were palmitic acid (hexadecanoic acid
), stearic acid (octadecanoic acid), oleic acid (cis-9-octadecenoic acid), elaidic acid (trans-9-octadecenoic acid) and linoleic acid (cis-9,cis-12-octadecadienoic acid) (Supelco, Bellefonte, PA)
