title: [Study on chemical constituents of volatile oil and trace elements from fruits of Clausena lansium].
abstract: OBJECTIVE
  To study and determine the chemical constituents of the volatile oil and the trace elements in the fruits of the Clausena lansium.
  
  
  METHODS
  The essential oils were extracted by supercritical fluid extraction (SFE) and separated on capillary columns with HP6890GC-5973MS. The components were quantitatively determined with normalization method, and were identified with GC-MS. And the trace elements were determined by ICP-MS and ICP-AES.
  
  
  RESULTS
  36 Components constituting 95% of the total essential oil were separated and identified, and 11 trace elements were identified.
  
  
  CONCLUSIONS
  18 Compounds were found from the fruit of C. lansium for the first time.
