The present study was carried out to characterize the constituents of Acacia polycantha seed oil and to assess its antimicrobial activity. Thirty two components were detected by GC-MS anal. being dominated by: 9,12-octadecadienoic acid Me ester (27.95%), Me stearate (17.13%), hexadecanoic acid Me ester (13.30%), 9-octadecanoic acid(Z) Me ester (9.57%). The antimicrobial activity of the oil was evaluated using the diffusion assay against: Gram pos.: Staphylococcus aureus and Bacillus subtilis; Gram neg.: Escherichia coli and Pseudomonasa aeruginosa and the yeast Candida albicans. The oil showed moderate activity against Pseudomonas aeruginosa and Staphylococcus aureus. However, it failed to exhibit activity against other test organisms. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Electric Literature of C20H40O2).
Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Electric Literature of C20H40O2
