The present study deals with the investigation of the neurobehavioral effects of the total alkaloid from seeds of Lepidium sativum [LSAF].The effect of LSAF on general pharmacology, thiopental induced hypnosis, locomotor activity, motor coordination, antianxiety and analgesic effect were studied. The animals were intraperitonealy treated with 50, 150 and 250 mg/kg LSAF to the respective treatment groups. The results revealed that LSAF considerably potentiated the thiopental induced hypnosis, decreased locomotor activity and motor coordination, and increased preference to plus maze open arm.
