The article describes the isolation and structural characterization of three antinematodal compounds from Euphorbia kansui against the nematode, Bursaphelenchus xylophilus. The compounds include 20-O-acetyl-[3-O-(2'E,4'Z)-decadienoyl]-ingenol, 20-O-acetyl-[5-O-(2'E,4'Z)-decadienoyl]-ingenol and 3-O-(2'E,4'Z)-decadienoylingenol. According to the authors, each compound showed the same antinematodal activity against the nematode at a minimum effective dose of 5µg/cotton ball.
