Background and purpose

 Subcritical water extraction has been considered due to advantages such as high speed, high efficiency and reduced amount of organic solvents used in the traditional way as well as due to its compatibility with the environment.

Materials and Methods

 In this study, the essences extraction from fennel seeds was performed by using subcritical water extraction and was compared with hydrodistillation method. Trans-anethole as the main combination has been carried out as a main goal of next experiments. Separating and diagnosis of the extracted trans-anethole were performed by GC-FID and GC / MS. The effect of temperature parameters, Average of particle size and flow intensity was studied on the extraction rate in subcritical water method. Taguchi experimental design was used to facilitate the process of testing and comparing the effective parameters. The ratio of the area of trans-anethole to the obtained internal standard from gas chromatography was calculated as evaluated criteria of parameters and extraction methods of essence from fennel seeds.

Results

 The results of Analysis of variance showed that the temperature and, Average of particle size have a significant effect on the amount of trans-anethole extraction. The highest ratio of trans-anethole to internal standard was obtained at 175 ° C, an average value of 0.398 mm, and a flow rate of 3 ml /min.

Conclusion

 The results of this study showed that the extraction by subcritical water in compare with hydro distillation method is a fast-high-efficiency method for extraction of trans-anethole as a valuable oxygen-containing compound.
