目的 考察不同种重楼成分-活性的整体相似性，建立重楼替代资源筛选的新方法。方法 采用HPLC法及镇痛、止血药理学模型比较了重楼属7种药用植物中重楼皂苷I、Ⅱ、VI、VⅡ的量及其镇痛、止血的药效，采用离差标准化法对数据进行标准化，以《中国药典》2015年版一部规定的重楼皂苷含量及阿司匹林、云南白药组“镇痛、止血”药效数据作为标准对照，建立了成分指数和活性指数，采用SPSS 20.0软件对成分指数和活性指数进行主成分分析和聚类分析。结果 重楼属7种药用植物主要皂苷类成分的总质量分数为0.125%～1.649%，其中长柱重楼最高（1.649%），大理重楼最低（0.125%）；云南重楼镇痛活性最强、小鼠出血停止时间（BT）最短、小鼠凝血时间（CT）最短；长柱重楼组小鼠活化部分凝血活酶时间（APTT）最短，黑籽重楼组最长；南重楼组小鼠凝血酶原时间（PT）最短；大理重楼组小鼠BT最长，多叶重楼组小鼠CT和PT均最长；云南重楼、南重楼、黑籽重楼聚为一类，多叶重楼、长柱重楼、大理重楼、毛重楼聚为一类，说明南重楼、黑籽重楼与云南重楼的成分-活性整体之间相似度较高，可考虑作为替代资源使用。结论 通过成分-活性等指标的整体相似性，评价不同种重楼之间的品质关系，为濒危植物重楼替代资源的寻找提供了思路和方法。

Objective To study the overall similarity of composition-activity of different kinds of Paridis Rhizoma, and establish a new method for selecting alternative resources. Methods The HPLC method was used to detect the content of polyphyllin I, Ⅱ, VI, and VⅡ, and pharmacological model of analgesic and hemostatic were used to detect the efficacy. The data were standardized using standard deviation method. Using polyphyllin I, Ⅱ, VI, and VⅡ at minimum 0.6%, aspirin and Yunnan Baiyao Group analgesic and hemostatic efficacy data as standard controls, we also established component and activity indexes. SPSS 20.0 Software was used to analyze the principal component analysis (PCA) and hierarchical cluster analysis (HCA) of these seven medicinal plants. Results The total content of the main saponins in seven medicinal plants of Paris genus ranged from 0.125% to 1.649%, and the maximum content (1.649%) was found in the P. forrestii while the minimum content (0.125%) was found in P. daliensis. The study also disclosed that P. polyphylla var. yunnanensis has the most active analgesic activity, and the time of bleeding (BT) in mice and the time of coagulation (CT) in mice were the shortest in P. polyphylla. The shortest mice activated partial thrombin time (APTT) was P. forrestii and the longest was P. thibetica. The shortest prothrombin time (PT) in mice was P. vietnamensis. The longest BT in mice was P. daliensis. The longest CT and PT in mice was P. polyphylla. PCA and HCA results showed that P. polyphylla var. yunnanensis, P. vietnamensis and P. thibetica were in the same class, while P. pubescens, P. daliensis, P. polyphylla, and P. forrestii were in another class. It is indicated that the overall similarity of component-activity of P. vietnamensis, P. thibetica, and P. polyphylla var. yunnanensis was higher, thus they can be considered as alternative sources. Conclusion The quality relations of different kinds of Paris genus were evaluated by the overall similarity of the component and activity index, which provides ideas and methods for the search of the replacement resources of the endangered plants.
