[Studies on chemical constituents of fat oil of Polygala tenuifolia].
OBJECTIVE
To study the chemical constituents of fat oil from root of Polygala tenuifolia Willd.


METHODS
The components were separated and identified by gas chromatograpy-mass spectrometry and elucidated on the standard mass spectral data and the percentages were determined by gas chromatographic area normalization method.


RESULTS
Eighteen constituents were separated and sixteen of them were identified.


CONCLUSIONS
The major components of the fat oil were established first time as oleic acid, linoleic acid, palmitic acid, eicosenoic acid and stearic acid, which make up 87.0%, 7.31%, 3.27%, 1.07%, 0.91% of fat oil respectively.
