ABSTRACT
AIM To evaluate saponins in Paris Polyphylla Smith var.chinensis (Franch.) Hara from twentyone growing areas.METHODS HPLC was adopted in the content determination of pennogenins { pennogenin-3-O-β-D-glu (1→3) [α-L-rha (1→2)]-β-D-glu (PGGR),polyphyllinsⅥ,Ⅶ,H} and dioscins (gracillin,polyphyllins Ⅰ,Ⅱ,Ⅴ),then SPSS 22.0 software was used for principal component analysis and cluster analysis.RESULTS Pennogenin was the main kind of Paris Polyphylla var.chinensis saponins,and PGGR,polyphyllins Ⅰ,Ⅴ,Ⅶ,H were the main effective constituents of this medicinal material.The comprehension scores of seven growing areas were more than zero,which was in sequence of Bazhong ＞ Qingchuan ＞ Yanjin ＞ Tongjiang ＞ Nanchuan ＞ Chongzhou ＞ Hongya.Twenty-one batches of samples were divided into four types,which was similar to cluster analysis results.CONCLUSION Bazhong,Qingchuan,Chongzhou,Hongya,Tongjiang in Sichuan,Yanjin in Yunnan,and Nanchuan in Chongqing are suitable for cultivating Paris Polyphylla var.chinensis,which can guarantee the stability of saponins.
