[Toxicological characteristics of thaliblastine[]

The toxic action of the antiphlogistic drug thaliblastin, containing 93-95 per cent of the alcaloid thalicarpine was investigated. With its single intraperitoneal injection to mice the DL10 of the drug amounts to 273-306 mg/kg, DL50-325-350 mg/kg and DL90-370-402 mg/kg. With its 5-day long administration the respective figures for mice are 102-165, 125-201 and 154-243 mg/kg and for rats--170, 203 and 272 mg/kg. The respective figures for a 20-day long introduction to mice are 155, 185 and 220 mg/kg. Introduction of thaliblastin in doses of DL10 single and multiply results in a marked loss of the mass in mice.
