牡丹在中国地区以不同的生态类型广泛分布。其根含有多种植物化学成分，具有很高的生物活性。然而，生态因子对威氏松根活性和化学成分的影响尚不清楚。本研究的目的是分析不同生态因子对威氏松根生物活性和植物化学成分的影响。对中国不同地区采集的7个卫氏原虫种群进行了评价。相关分析结果表明，年平均温度、海拔、全钾和有机质4个主要生态因子与威氏松根生物活性有较强的相关性。此外，主要生态因子还与柚皮苷、没食子酸、苯甲酰牡丹苷、芍药苷的含量呈高度正相关。主成分分析结果支持四种主要代谢物作为主要贡献成分。通过系统聚类分析，将所有群体划分为G1、G2和G3三个群体。在上述四种生态因子、四种有效成分和生物活性方面，G1组均明显优于其他两组。年平均温度较低、海拔较高、土壤全钾和有机质含量较高的威氏松根具有较高的生物活性。这些数据拓展了对牡丹根生物活性和植物化学成分的研究，对该草本牡丹栽培过程中生态因子的选择具有指导意义。
Paeonia veitchii has been widely distributed in China under different ecological types. Its roots contain diverse phytochemical constituents, which possess very high bioactivities. However, the influence of ecological factors on activities and ingredients of P. veitchii roots still remains unknown. The purpose of this research was to analyze the variation in bioactivities and phytochemical composition of P. veitchii roots upon exposure to various ecological factors. Seven P. veitchii populations collected from different regions in China were evaluated. The results of correlation analysis suggested that four major ecological factors, including average annual temperature, elevation, total potassium, and organic matter, had a strong correlation with the bioactivities of P. veitchii roots. Further, the major ecological factors were also highly correlated with the contents of naringin, gallic acid, benzoylpaeoniflorin, and paeoniflorin. The principal component analysis results supported four major metabolites as the main contributing ingredients. All populations were classified into three groups, G1, G2, and G3, through hierarchical cluster analysis. G1 showed more significant advantages in the above‐mentioned four ecological factors, four active ingredients, and bioactivities compared to the other two groups. P. veitchii roots growing at lower average annual temperature, high elevation, rich total potassium and organic matter in the soils were presumed to have relatively higher bioactivities. These data expand the study on the bioactivities and phytochemical composition of P. veitchii roots and have a guiding significance for the ecological factor selection during the cultivation process of this herbaceous peony species.
