Parabenzoin trilobum

A number of sesquiterpenes have been demonstrated to have pronounced biological activity ( ) among the non-volatile compounds the sesquiterpene lactones are best known (M) but other oxygenated sesquiterpenes are also known to be active. For example, the role of gossypol, a dimeric sesquiterpene and structurally related compounds has been investigated (21,22). The oxygenated sesquiterpenes, shiromodiol monoacetate and diacetate, from Parabenzoin trilobum (=Lindera triloba Blume) possess potent anti feeding activity toward Spodoptera litura larvae (85). 

Other antifeedants such as shiromodiol diacetate (50) have been isolated from Parabenzoin trilobum (syn. Lind-era, Lauraceae). These compounds are active against feeding by polyphagous and oligophagous insects at the 0.05-0.1% level in artificial diets (Mabry and Gill, 1979 Munakata, 1977).
