The antifeedant, insecticidal and insect growth inhibitory activities of triterpenoid saponins from Clematis aethusifolia Turcz against Plutella xylostella (L.).

The present results provide evidence that triterpenoid saponins from C. aethusifolia, particularly those monodesmosidic saponins with a free 28-COOH group, have the potential to be developed as pesticides to control P. xylostella.
