Objective: To study the chemical constituents and bioactivity of essential oil from Artabotrys hexapetalus. Method: The essential oil was extracted by hydrodistillation and separated by capillary GC. The chemical constituents were determined by normalization and were identified by MS. Result: Sixty-eight chromatographic peaks were detected and 53 compounds were identified

which were 89.32% of the total essential oil. The essential oil from A. hexapetalus showed inhibitory activity against staphyococcus aureus rosenbach

escherichia coli

bacillus subtilis and exhibited higher activity to restrain liver cancer cells(BEL-7402)

with IC50 values of 12.07 mg·L-1. Conclusion: Volatile oil has been extracted from A. hexapetalus. and the compounds have been identified for the first time

containing many active ingredients. This study provides experimental evidence for the further research and exploitation of A. hexapetalus.
