          ABSTRACT    OBJECTIVE  To  establish  the  methods  to  identify  the  chemical  components  of  Ixeris  chinensis,  and  determine  the
          contents  of  7  components (chlorogenic  acid,  luteolin,  quercetin,  rutin,  protocatechuic  acid,  isochlorogenic  acid A,  luteoloside).
          METHODS HPLC-Q-Exactive-MS was used to identify the chemical components of I. chinensis. The contents of 7 components in
          I.  chinensis,  including  chlorogenic  acid,  were  determined  by  HPLC-MS/MS.  RESULTS  A  total  of  45  components  were  identified
          in I. chinensis, including 20 organic acids, 13 flavonoids, 4 fatty acids, 4 amino acids, 3 nucleosides, and 1 coumarin. The linear
          range  of  chlorogenic  acid,  luteolin,  quercetin,  rutin,  protocatechuic  acid,  isochlorogenic  acid  A  and  luteoloside  were  503.00-
          25  150.00,  42.00-2  100.00,  5.05-252.50,  20.05-1  002.50,  25.10-1  255.00,  750.00-37  500.00,  196.00-9  800.00  ng/mL (r≥0.999  2),
          respectively.  RSDs  of  precision,  stability  and  reproducibility  tests  were  all  less  than  3.00% (n=6),  and  average  recovery  ranged
          from  96.72%  to  105.84% (all  RSD<4.00%,  n=6).  The  contents  of  7  components  in  3  batches  of  I.  chinensis  were  1  145.77-
          3  261.25,  23.75-97.90,  0.92-2.12,  1.06-23.18,  9.35-21.85,  833.25-1  045.58,  199.56-1  869.78  μg/g,  respectively.  CONCLUSIONS
          The established methods for identification and content determination are rapid and simple, and can be used for the identification of
          chemical components and the content determination of 7 components in I. chinensis.
