Study on chemical compositions and antimicrobial activity of the volatile oil of Dictyophora echinovalvata was written by Tan, Dongfei;Wu, Ruojing;Liang, Ming;Lin, Yuexin. And the article was included in Junwu Xitong in 2002.Recommanded Product: (E)-Dodeca-9,11-dien-1-yl acetate The following contents are mentioned in the article:
The volatile oil of Dictyophora echinovalvata was extracted by water-steaming method with ether as extractant and the extraction rate was 0.45%. The chem. compositions of the volatile oil had been separated and identified by means of Gas Chromatog.-Mass Spectrometry. Twenty nine compositions were identified from 36 separated peaks, and the major components were oxacyclotetradecan-2-one, 13-methyl- (23.53%), 9,12-octadecadienoic acid (Z,Z)- (17.56%), selinene (12.37%), hexadecanoic acid (8.20%), 9-hexadecenoic acid (7.84%), (-)-lepidozenal (7.82%), etc., which were made up to 97.76% of the quantity of volatile oil. The antimicrobial activity of the volatile oil was preliminarily tested in the suspensions of Escherichia coli, Staphylococcus aureus, Saccharomyces cerevisiae, Candida albicans, Aspergillus niger, Penicillium chrysogenum and Rhizopus nigricans, resp., when the volatile oil was diluted by 100 times, 50 times and 25 times. The results showed that P. chrysogenum and S. cerevisiae were the most sensitive, next R. nigricans and A. niger, and then C. albicans, S. aureus and E. coli. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Recommanded Product: (E)-Dodeca-9,11-dien-1-yl acetate).
(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. 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.Recommanded Product: (E)-Dodeca-9,11-dien-1-yl acetate
