In this study， by investigating Paris polyphylla Smith var. chinensis in different regions， the 49 samples of Paris polyphylla Smith var. chinensis were collected for the determination and analysis of the agronomic characteristics and the polyphyllin content. In addition， the 5 samples from the main planting areas were selected for the determination of soil nutrients. Last， the correlation between soil nutrients and polyphyllin content was analyzed. The results showed that the proportion of the content of polyphyllin Ⅶ was the largest in the total content of polyphyllin in the four kinds of Paris polyphylla Smith var. chinensis， among which the content of polyphyllin in Paris polyphylla Smith var. chinensis in Chenda Town of Sanming City and Taolin Village， Zhaili Town of Guangze County was the highest， the content of polyphyllin in Paris polyphylla Smith var. chinensis in Longyan City was higher， and the total content of polyphyllin in Paris polyphylla Smith var. chinensis in Nan
