The spectrum effect relationship of Tripterygium Wilfordii Hook.f. [PDF]
, 2016 雷公藤的药理作用广泛，其中抗炎和免疫抑制作用尤其突出，临床多用于类风湿性关节炎、自身免疫疾病如肾病综合征等的治疗。但其不良反应不容忽视，雷公藤的不良反应涉及多器官、多系统且多数患者不能耐受。其不良反应发生的主要原因有雷公藤化学成分复杂且其药效、毒性物质基础尚不明确，缺乏科学、有效的质量评价和控制方法，导致不同厂家生产的雷公藤制剂疗效及毒副作用差异大，临床上缺乏使用指南等。因此，如何快速识别雷公藤中的药效成分和毒性成分，建立科学、有效的质量评价和控制方法，提高雷公藤制剂质量是促进雷公藤在临床安全使用的前提。
