Chinese bittersweet, Celastrus angulatus Max., is a traditional insecticidal plant in China. Since 1980s, the insecticidal plant has been investigated by multi-subjects crossed research in the world. This paper reviews the bioactivities of the compounds from the plant in five aspects, including insect antifeedant action, insecticidal action, insect narcosis, fungicidal action and anticancer action. The advances of the research on the insecticidal mechanisms of major component celangulin Ⅳ and Ⅴ from the plant are summarized. It is elucidated further that celangulin Ⅳ could target the neuromuscular synapse on the insect, but the celangulin Ⅴ is believed to act on the insect digestive system, and it is predicted that there could be receptors on plasmelemma and organelle membrane of the midgut cells of pest larva. The paper also reviews the field application technology and environment toxicology of the celangulin preparations. Finally, the present problems and the future prospect are discussed.
