Abstract: From the seed oil of Yunnan Euonymus bungeenus Maxim., four β-dihydroagarofuran sesquiterpene polyol esters (Ⅰ, Ⅱ, Ⅲ and Ⅳ) have been isolated by reverse phase HPLC. On the bails of spectral analysis and chemical reaction, Ⅰ, Ⅱ, and Ⅲ which have been first reported in this plant, were identified as known compounds, and IV was elucidated as new compound. A preliminary insecticidal test of Ⅰ against insect Pieris rapae showed that Ⅰ had moderate insect antifeedant effect.
