基于气候因子的全国栽培太子参品质区划分析(1)
[摘要] 运用Maxent模型对气候因子进行逐层筛选分析，综合太子参环肽B和多糖2个内在质量评价指标构建回归模型，分析气候因子与太子参化学成分间的内在联系，寻找影响药材质量的关键气候因子，并基于关键气候因子明确太子参品质的空间分布规律。结果显示，多糖与气候因子无显著相关性，提示该指标并不是气候主导型的代谢物质。而太子参环肽B可与降水量构建回归模型，且区划结果显示，太子参环肽B含量总体呈现从东南向西北先升高后降低的趋势，这与全国降水量变化情况相一致，表明降水量是影响太子参药材中太子参环肽类物质积累的关键气候因子。

Polysaccharides and pseudostellarin B the two internal quality evaluation index were combined to analyse the interlinkages between climate factors and chemical constituents in order to search for the critical climate factors of Pseudostellaria heterophylla. Then based on the key climate factors to explicit the quality spatial distribution of P. heterophylla. The results showed that polysaccharides and climatic factors had no significant correlation ......
