Cinnamomum petrophilum leaves extracts were prepared respectively by steam distillation, ether extraction and supercritical CO_2 extraction, to obtain product yields of 2.09%, 3.14% and 3.75% respectively. Safrole contents of the extracts were 94.9%, 36.1% and 15.9%, respectively, analyzed by GC, which was confirmed by GC-MS. For the substances of molecular weight between 30 - 550u, the essential oil produced by steam distillation contained α-limonene, linalool and 2-methyl-3-(2-propenyl)phenol besides safrole. The test results showed that steam distillation was the best technology to prepare safrole from C.petrophilum leaves.
