Tri dec 1 ene 3 5 7 9 11 pentyne an ovicidal substance from xanthium canadense


, : Tri dec 1 ene 3 5 7 9 11 pentyne an ovicidal substance from xanthium canadense. Agricultural and Biological Chemistry 41(9): 1801-1802

The methanol extract of roots of X. canadense were examined for ovicidal activity and a C13 enepentayne substance was isolated as the active principle. This substance was concluded to be tridec-1-ene-3, 5, 7, 9, 11-pentayne. The ovicidal activity of the C13 enepentayne to the fruit-fly, Drosophila melanogaster and the house-fly, Musca domestica, was tested using the paper disk method. Apparently the acetylenic groups contribute to the ovicidal activity, and its activity increases with an increase in the number of conjugated triple bonds in the carbon chain of polyacetylene.
