摘　　要：为探究人参(Panax ginseng)皂苷含量的空间变异性及其影响因子,该研究以采自黑龙江、吉林、辽宁的28份六年生人参为研究对象,测定人参中9种单体皂苷含量,用单因素方差分析方法研究了人参皂苷含量的空间变异性。并用主成分分析、相关性分析和冗余分析法进行人参皂苷含量与气候因子、土壤因子的相关性分析。结果表明:吉林与辽宁人参的皂苷含量接近,且其含量高于黑龙江人参;影响皂苷含量的气候因子主要是降水,高温、日照时间是皂苷含量的限制因子;全氮、铁、钾、有机质、pH值、锰、磷、锌对人参化学品质的影响较大。Aims This study aimed to reveal how ginsenosides content in Panax ginseng varied spatially and the regulating roles of environmental factors.Methods Twenty eight P.ginseng samples were collected from Heilongjiang,Jilin and Liaoning provinces,and nine kinds of ginsenosides content in P.ginseng were measured.The one-way ANOVA was used to evaluate their spatial variations.The method of UPLC was employed to determine the content of nine kinds of ginsenosides in P.ginseng.The principal component analysis（PCA）,correlation analysis（CA） and redundancy analysis（RDA） were used to analyze the relationship between ginsenosides content and ecological factors（including climate and soil factors）.Important findings The results showed that the content of ginsenosides in P.ginseng from Jilin and Liaoning was similar,and higher than that in Heilongjiang.Precipitation was the most important climate factor affecting the contents of ginsenosides.High temperature and strong sunshine limited the content of ginsenosides.The analysis on ginsenosides and soil factors indicated that soil nitrogen content,Fe,K,organic matter,p H value,Mn,P,Zn all had significant influences on the content of ginsenosides.
