【摘要】 [Objective] A new method for the industrial extraction of essential oil from Ramulus Cinnamomi was selected. [Method] With cinnamaldehyde as standard substance, the content analysis was conducted by TLC and HPLC. The yield and purity essential oil extracted from Ramulus Cinnamomi by supercritical-CO2 extraction (SFE-CO2) method were compared with that by steam distillation. [Result] In the concentration range of 0.524 9-2.099 4 μg/ml, cinnamaldehyde content showed a linear relationship with peak area. And their linear regression equation was Y=6.033 3×106x+0.457 3×106, r=0.999 8. The yield of essential oil from Ramulus Cinnamomi by supercritical-CO2 extraction (SFE-CO2) method increased 7.33 times than that by steam distillation. And the purity of essential oil from Ramulus Cinnamomi by supercritical-CO2 extraction (SFE-CO2) method was higher. [Conclusion] Extracting essential oil from Ramulus Cinnamomi by SFE-CO2 method could enhance the extracting yield.
