%X <p>The volatile oil contains many kinds of active ingredients， which can be used as an indicator for the quality evaluation of Asari Radix et Rhizoma， and the difference of volatile oil components of different origins is of great significance for the quality research and development and application of Asari Radix et Rhizoma. Gas chromatography-mass spectrometry（GC-MS） was used to qualitatively and relatively quantify the volatile oil components of different origins， combined with data analysis software， and the differential compounds of different origins were identified by cluster analysis（HCA）， principal component analysis（PCA） and orthogonal partial least squares discriminant analysis（OPLS-DA）. The results showed that a total of 59 compounds were detected in 25 batches of Asari Radix et Rhizoma<italic/>samples， which could be divided into three categories according to different origins. Further analysis showed that the difference in volatile components of Asari Radix et Rhizoma was significantly correlated with different origins， and 11 compounds such as α-terpineol， myristic ether and camphene were identified as different components of different origins. The differential components screened by chemometrics can be used to distinguish different origins and provide a comprehensive reference for the rational use of Asari Radix et Rhizoma resources.</p>
