Two nematicidal polyacetylenes, 3-cis, 11-trans- and 3-trans, 11-trans-trideca-1, 3, 11-triene-5, 7, 9-triyne, were isolated from flowers of Carthamus tinctorius L., by column chromatography and high speed liquid chromatography under the dark condition.
The nematicidal activities of 3-cis, 11-trans- and 3-trans, 11-trans-isomer to Aphelenchoides besseyi were 80% at 10 ppm and 95% at 1 ppm, respectively.
