Abstract:
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.
