Three Antinematodal Diterpenes from Euphorbia kansui
Abstract:Three compounds, 20-O-acetyl-3-O-(2′E,4′Z)-decadienoyl]-ingenol (1), 20-O-acetyl-5-O-(2′E,4′Z)-decadienoyl]-ingenol (2) and 3-O-(2′E,4′Z)-decadienoylingenol (3), were isolated from Euphorbia kansui under the bioassay-guided method. Each compound showed the same antinematodal activity against the nematode, Bursaphelenchus xylophilus, at a minimum effective dose (MED) of 5 μg/cotton ball.
Keywords:antinematodal activity  Bursaphelenchus xylophilus  diterpenoid  ingenane  Euphorbia kansui
