为了探讨生态因子与桃儿七根及根茎中鬼臼毒素及总木脂素含量的相关性,采用HPLC测定5个省区87份桃儿七样品的鬼臼毒素含量,采用UV测定总木脂素含量;结合生态因子(地形、土壤、气候)采用SPSS软件对其进行相关与回归分析。含量测定结果表明产地桃儿七中鬼臼毒素与总木脂素的含量差异较大,分别达到1.001%~6.230%,5.350%~16.34%。SPSS相关与回归分析发现鬼臼毒素含量与总木脂素含量呈线性正相关;采样区域内,桃儿七中鬼臼毒素、总木脂素含量与纬度、年均降雨量呈强正相关关系,与土壤pH、土壤中有机质含量呈强负相关关系,与速效钾分别呈较弱、强正相关关系,与坡度、年均气温均呈较弱负相关,且鬼臼毒素含量与速效磷呈较弱正相关关系。
In order to investigate the relationship between the ecological factors and the content of podophyllotoxin and total lignin in seven peaches and rhizomes, the content of podophyllotoxin in 87 samples of peach seven in five provinces and autonomous regions was determined by HPLC. Total lipids Vegetation content and ecological factors (topography, soil, climate) were analyzed using SPSS software. The content determination showed that the contents of podophyllotoxin and total lignans varied greatly from 1.001% to 6.230% and 5.350% to 16.34% respectively. There was a linear positive correlation between podophyllotoxin content and total lignan content by SPSS correlation and regression analysis. There was a strong positive correlation between podophyllotoxin and total lignan content in latitudes and latitudes and annual average rainfall in the sampling area , And soil pH, organic matter content in soil showed a strong negative correlation, and available potassium were weak, strong positive correlation, and slope, the average annual temperature showed a weak negative correlation, and the podophyllotoxin content and available phosphorus was Weak positive correlation.
