Compounds components in extracts were identified by GC-MS. Main compounds were phenylpropanoids and terpenoids. The top-ten most of compounds in betel oil were shown in chromatogram and list in Figure1. The majority of compounds were phenylpropenoids approximately 65.9% including isoeugenol acetate (21.2%), eugenol (20.2%), 4-allylpyrocatechol diacetate (14.4%), trans-propenyl guaiacol (4.8%), eugenol acetate (4.3%) and isoeugenol (1.0%). The second most ones were sesquiterpenoids approximately 13.2% including β-caryophyllene (6.8%), α-humulene (2.4%), α-gurjunene (2.3%) and δ-cadinene (1.7%) (Figure1).
