[Comparisons of volatile components in different parts of three species of Rhizoma Curcumae].
OBJECTIVE
To provide the scientific basis for the reasonable development and use of the leaves of Rhizoma Curcumae.


METHODS
To extract the volatile oil from roots and leaves of three species Rhizoma Curcumae by steam distillation and isolate these products with the method of gas chromatography-mass spectrum. Taking Nist98 standard mass spectrometer database and contrast as control, the structure of the mass spectrogram was identified, and the relative contents of the components were determined with area normalization method.


RESULTS
The anti-tumor active constituents such as curdione and germacrone in the leaves had the greater content than in its rhizome.


CONCLUSIONS
The varieties of volatile components in different parts of three species of Rhizoma Curcumae are similar, but their contents are obviously various. We can make the leaves of Rhizoma Curcumae for recycling use.
