Abstract： To evaluate the quality of Nardostachys jatamansi from different producing areas and to identify its geographical origin，wild medicinal materials from five regions （Sichuan， Gansu， Qinghai， Yunnan and Xizang） were examined microscopically.The contents of nardosinone， volatile components，and18 elements （including Al， B，Ba， Ca，etc.） were determined. Chemometric models were employed for origin discrimination. Theresults showed differences in the number of stone cels and the color of parenchyma cells among N. （204号 jatamansi from diferent origins.Furthermore，the contents of metabolites Varied significantly across the five geographical groups.Discrimination analysis models based on volatile components and inorganic elements accurately traced the origin of N. jatamansi.Using variable importance calculated by the models， six volatile components （dl-Neoisolongifolene， Seychellene，Aristolediene， a -Humulene， αa -Selinene and Ionene） and eleven elements （Ca，Mg，Co，Fe，Cu，Cd，Mo，Mn，Al，NaandNi）were successfullyidentified as makersfor tracing the geographical origin ofN. jatamansi.
