Gentiana rigescens and Swertia mileensis belonged to Gentianaceae are endemic plants in China. Four iridoids (loganic acid, swertiamarin, gentiopicroside and sweroside) in Grigescens and Smileensis were determined by HPLCDAD. Their chemometrics characterizations were analyzed with multiple statistical analyses. The results showed that there were differences of chemometrics characterization of the iridoids between the two species. All the samples of Grigescens could be classified into four groups based on contents and percentage contents of the four iridoids. Content of loganic acid had significant negative correlation with longitude (R=-0348,P<005) and had significant positive correlation with altitude (R=0307, P<001). Longitude had significant negative correlation with content of swertiamarin (R=-0592, P<001) and had significant positive correlation with percentage content of sweroside (R=0245, P<005). However, content of gentiopicroside hadn’t correlation with geographical factors (P>005) in the study.
