(2012) [27] 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.
Among 44 identified compounds major were Pentadecane (2.70%), Tetradecane (6.77%), Heptadecane (5.64%), Tetradecane, 2, 6, 10-trimethyl (2.03%), Phenol, 3,5-bis(1,1-dimethylethyl)-(3.39%), Hexadecane, 2,6,11,15-tetramethyl-(2.03%), Hexadecane (6.77%), Pentadecane, 8-hexyl-(5.42%), Pentatriacontane (2.26%), Eicosane, 10-methyl-(3.9%), Tetrapentacontane (4.96%), Tetratetracontane (3.39%), Eicosane (7.22%), Hexatriacontane (8.58%), Tritetracontane (4.74%) and Docosanoic acid, docosyl ester (11.05%).Most of these compounds showed antimicrobial activities and contributed in plant defense mechanism (Kokate et.
The concentrations of specific metabolites were significantly higher in IPD and T2DM patients, compared with the control group, including linoleic acid, oleic acid, docosanoic acid, cholesteryl-[beta]-D-glucoside, and 1,2-distearoyl phosphatidyl serine, whereas other metabolites, such as lysophosphatidylcholine (lysoPC), lysophosphatidyl ethanolamine (lysoPE), DHEA-S, and 5-hydroxykynurenine, were significantly lower in these groups.
In a study on the biosynthetic pathway of NA formation, scientists found that NA is formed through elongation of the carbonic chain of erucic acid (docosanoic acid) (Lecerf 1980).
