摘　　要：目的:分析太子参指标成分与气候因子的相关性。方法:采用相关性分析(CA)、偏最小二乘分析(PLS)、PCA排序分析等统计方法研究太子参中指标成分与气候因子的相关性,探究影响太子参指标成分积累的主要气候因子。结果:产地与采收时间对太子参中指标成分含量均存在影响。气候因子中月最低气温、月平均气湿、月降水量以及年降水量是影响太子参指标成分含量的主导因素。结论:通过气候因子与指标成分间的正负相关性分析,可以解释太子参传统采收时间的合理性以及江苏句容太子参环肽B含量较高的原因。Objective： To analyze the correlation between index components and climatic factors of Pseudostellariae Radix. Methods： Correlation analysis（ CA）,partial least square（ PLS） and PCA ordination were applied to analyze the correlation of index components in Pseudostellariae Radix and climatic factors,and to explore the main climatic factors affecting the accumulation of index components in Pseudostellariae Radix. Results： The origin and harvest time had influence on index components. The monthly minimum temperature,monthly average humidity,monthly precipitation and the annual precipitation were the main factor influencing the content of index components. Conclusion： Through the positive and negative correlation between climatic factors and index components,it could explain the rationality of traditional harvesting time and the reason of high content of heterophyllin B in Pseudostellariae Radix from Jiangsu Jurong.
