Abstract

By Irwin Horntein's method, Rotenone from plant have been separated and determinated. Acetone was used as the solvent for extracting rotenoid. The dilute extract from root has expressed a pesticide activity to diamond-back moth (Plutella xylostella). We have studied on determination concentration of extracts that pesticide activity is high for in vivo testing.
