The identification of filaricides in 3 medicinal plants is reported. The compounds carapolide A, mexicanolide-methylangolensate mixture from C. procera and oliverine from Polyalthia suaveolens or Pachypodanthium staudtii when tested at 10-100 micro g/ml were found to exhibit considerable microfilaricidal activity after 24 h of incubation. Oliverine was found to be filaricidal when tested against adult female O. volvulus at 100 micro g/ml. Preliminary toxicity studies in mice showed carapolide A and the mexicanolide-methylangolensate mixture to be relatively non-toxic, whereas, oliverine had a minimal lethal dose of 8 mg/kg bwt.
