D. elliptica (Wall.) Benth. is the evergreen shrub and climbing plant with the woody stem in Leguminosae family. This East Asian plant is called “Lotin or Hang Lai Daeng” in Thai and is world-famous for being used as organic piscicide, acaricide and insecticide in veterinary medicine.1 Rotenone (also known as nicouline, dactinol or tubatoxin) is an isoflavonoid primarily found in Leguminosae family, especially in Derris plants (Figure 1). The toxicity of rotenone was classified as a medium hazardous class II pesticide by World Health Organization (WHO), indicating LD50 at the range of 132-1500 mg/kg. 2 Since this botanical compound has been used widely as the fish killer, the United States Environmental Protection Agency (USEPA) also reported the very low bioaccumulation of rotenone-treated fish, for example, consuming approximately 274,000 rotenone-treated fish would develop acute toxicity in human.3 Thus, it is claimed to be safe compound for human with properly use. On the other hands, its neurotoxicity has been evaluated as the potential substance to induce Parkinsonism in animal models which are beneficial to evaluate numerous compounds to treat Parkinson’s disease.4,5
