Objective: To study the volatiles oils of Elaeagnus henryi . Method: The constituents of volatiles oils of E. henryi were analyzed by head-space solid micro-extraction

coupled with GC-MS. Result: 21 compounds were identified from the E.henryi and account for 50.95% of the total volatiles.Alcohols

acids

esters

alkenes and alkanes were dominant volatiles. Conclusion: The main compounds were campesterol (7.09%)
