Insect antifeedant ryanodane diterpenes from Persea indica
The new ryanodane diterpenes cinnzeylanone, ryanodol 14-monoacetate, and epi-cinnzeylanol have been isolated from Persea indica(Lauraceae). The structure of cinnzeylanone has been determined by X-ray analysis. These compounds proveds to be antifeedants against Spodoptera litura. Cinnzeylanol and ryanodol were the most active antifeedants of this plant, with a range of activity close to that of ryanodine. THis is the first report on the antifeedant effects of this class of diterpenes. Their structure-activity relationships and possible mode of action are discussed.
