Analysis of the essential oil from the seeds of toona sinensis by GC-MS

OBJECTIVE: To study the chemical constituents of the essential oil from the seeds of Toona sinensis (A. Juss.) Roem. METHODS: The essential oil was obtained by steam distillation. The chemical components were separated and identified by GC-MS. The relative content of each component was determined by area nomalization. RESULTS: 40 peaks were separated and 39 of them were identified representing 86.96% of the total contents. CONCLUSION: The main constituents of the essential oil from the seeds of Toona sinensis were found to be alkenes (88.94%) which mostly were Sesquiterpenes. The relative contents of trans-caryophyllene, γ-elemene, elemene, α-longipinene and calarene were higher than that of others. The study was reported for the first time.
