Seeds are very important for the plants to reproduce continuously in the existing world. The human life depends partly on the seeds derived from plants either by means of cooked or raw or in the form of active principles in case of pharmacol. use. So, it is essential to study the nutrients present in the seeds and also its fatty acid content as it is an important factor in giving antimicrobial activity. The components were assessed by means of anal. technique called GC-MS. The obtained results showed that it contains higher oleic acid and 9-Octadecenoic acid (Z)-Me ester and found to be effective against fungi Aspergillus flavus. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8COA of Formula: C20H40O2).
Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.COA of Formula: C20H40O2
