概要
OBJECTIVE
To study the chemical constituents of the essential oil from the roots and rhizomes of Patrinia rupestris.
METHODS
The essential oil was extracted by steam distillation. The components were separated and identified by gas chromatography mass spectrometry and elucidated on the standard mass spectral data. Gas chromatography showed their percentages by area normalization method.
RESULTS
Seventeen constituents were identified which make up 74.57% of the oil.
CONCLUSIONS
Transcaryophyllene (38.41%) was the main constituent, and other constituents include alpha-gurjunene, caryophyllene oxide, humulene, 9,12-octadecadienoic acid, etc.
