| Abstract: | 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 of 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 3×106 X+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. |
