[Study on chemical constituents of volatile oil and trace elements from fruits of Clausena lansium].

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