✦ Synopsis

Oleanolic acid isolated from the sapogenin fraction of the roots of American ginseng, Panax quinquefolium (Araliaceae) was bioassayed by leaf disc method for feeding-deterrence using two lepidopterous insects Spilosoma obliqua and Spodoptera litura. This triterpenic acid was found to be a potent antifeedant under laboratory conditions. Oleanolic acid displayed 98.75% and 97.26% feeding-deterrence at 3000 ppm concentration against insects S. obliqua and S. litura, respectively. Azadirachtin was used as a standard.
