[Comparison study of different methods for extracting volatile oil from bergamot].
OBJECTIVE
To test different methods for extracting volatile oil from bergamot.


METHODS
The determination of bergapten was carried out by RP-HPLC. Four different ways of organic solvent extraction, steam-input distillation, distillation of the material mixed with water and press extraction were compared.


RESULTS
Bergapten wasnt extracted by ways of steam-input distillation and distillation of the material mixed with water.


CONCLUSIONS
The steam distillation extraction can be taken to extract volatile oil from bergamot for protecting humans' skins.
