Abstract
Leaves of Physalis peruviana gave glycoside esters derived from (24E,2 2R)-1 alpha,22-dihydroxy-3 beta-D-glucopyranosyloxy)-ergosta-5,24-dien -26-oic acid and from (24E,22R)-1 alpha,3 beta,11 beta,22-tetrahydroxy ergosta-5,24-dien-26-oic acid. These compounds reduced the growth of H elicoverpa zea larvae to 50% of control size at concentrations of 5-11 0 ppm in artificial diets, but no toxic effect was observed in a stand ard brine shrimp bioassay.
