[pharmacological action] the volatile oil from fruits has a specific effect on the central nervous system, similar to chlorpromazine. Intraperitoneal injection of its emulsifier 0.15-0.3 g / kg can enhance the sleep time of pentobarbital in rats, but it has no adrenaline blocking effect. It can partly antagonize the hyperactivity and temperature rise caused by mescalin. The other characteristic is that it has synergistic effect with d-amphetamine, which can significantly enhance the effect of d-amphetamine on raising body temperature and cause death of animals. The toxicity of volatile koji itself is low, and the rats can tolerate 0.6 g / kg.
