RESUMO
<p><b>OBJECTIVE</b>To study and determine the chemical constituents of the volatile oil and the trace elements in the fruits of the Clausena lansium.</p><p><b>METHOD</b>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.</p><p><b>RESULT</b>36 Components constituting 95% of the total essential oil were separated and identified, and 11 trace elements were identified.</p><p><b>CONCLUSION</b>18 Compounds were found from the fruit of C. lansium for the first time.</p>
