The aim of this study was to evaluate the chem. composition and the larvicidal activity of Brunfelsia uniflora leaf and flower extracts against Aedes aegypti larvae. Twenty-four compounds were found in the leaf extract, and the major compounds were phytol (23.1%), 9,12,15-octadecatrienoic acid, Et ester (21.3%), and hexadecanoic acid, Et ester (12.8%). In the flower extract, twenty-four compounds were also identified and the major compounds were α-amyrin (35.7%), β-amyrin (16.4%), and (EE)-geranyl linalool (9.6%) by gas chromatog. coupled to mass spectrometry. The larvicidal activity was evaluated by larval immersion test. The lethal concentrations (LC) obtained from leaf extract were LC50 = 4.89 and LC99.9 = 11.14 mg/mL and from flower extract were LC50 = 3.82 and LC99.9 = 11.03 mg/mL, and the pos. control presented LC50 = 0.40 and LC99.9 = 1.14 mg/mL. Thus, B. uniflora extracts are promising alternatives to control A. aegypti larvae. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Related Products of 763-69-9).
Ethyl 3-ethoxypropanoate (cas: 763-69-9) 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. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Related Products of 763-69-9
