| Abstract: | "Coreopsis lanceolata is an Asteraceous plant known to contain semiochemicals active against nematodes and leukemic agents. The objective of the study was to discover termite resistant constituents from C. lanceolata stems. Five compounds were isolated from C. lanceolata stems. These compounds were identified as 5-phenyl-2-(1-propynyl)-thiophene (1), 1-phenylhepta-1,3,5-tryne (2), beta-sitosterol (3), succinic acid (4), and protocatechuic acid (5), respectively; they were confirmed by spectroscopic analysis. Their antitermitic effects were evaluated with the no-choice feeding test against Coptotermes curvignathus. Of the isolates, 5-phenyl-2-(1-propynyl)-thiophene (1) and 1-phenylhepta-1,3,5-tryne (2) showed strong potent antitermitic activity. Our findings suggested that compounds 1 and 2 isolated from C. lanceolata stems appears to be the active ingredients" |
