【Abstract】 The essential oil of oak moss concrete was extracted by volatile oil content equipment The chemical compositions and their relative contents were analyzed by GC and GC/MS.A Supelco 5 fused silica capillary column (30 m×0.32 mm i.d.;0.25 μm thickness) and a flame ionization detector (FID) were employed in GC analysis. The temperature program included temperature increase of 4 ℃/min from 50 ℃ to 250 ℃, and a 10 min isothermal period at 250 ℃. Mass spectra were obtained by electron impact at 70 eV and a source temperature of 170 ℃. Twenty four volatile compounds of oak mass concrete were identified, which comprised more than 83% of volatile fraction.The major components were diethyl phthalate, α terpineol, cedrane and linalool.更多还原
