Chemical constituents and radical scavenging activity of Cuscuta pedicellata seed extracts was written by Abdallah, Walid E.;Elsayed, Wael M.;Abdelshafeek, Khaled A.. And the article was included in International Journal of ChemTech Research in 2016.Application In Synthesis of Methyl nonadecanoate The following contents are mentioned in the article:
The seeds oil of Cuscuta pedicellata was extracted with pet. ether in a Soxhlet for two days and it’s constituents were identified using GC/MS anal. It was found that, the lipid constituents of pet. ether was found as oily residue which saponified to afford the unsaponifiable materials (saturated hydrocarbons, sterols and triterpenes) and 15 fatty acids which were identified by GC/MS analyses. The flavonoids were isolated from the Et acetate fraction and identified as: : Genkwanin, Astragalin, kaempferol and quercetin. The antioxidant activity of different extracts (pet. ether, unsap., fatty acids, 70% methanol, chloroform and Et acetate) were evaluated.Antioxidant properties were determined using the 2,2-diphenyl-1-picryl-hydrazyl (DPPH) free radical. It was observed that methanol extract exhibited highest DPPH activity followed by Et acetate extract This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Application In Synthesis of Methyl nonadecanoate).
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.Application In Synthesis of Methyl nonadecanoate
