Fatty Acid and Non-Fatty Acid Components of the Seed Oil ofCelastrus paniculatuswilld.

The yield and chemical composition of the seed oil of Celastrus paniculatus were determined by solvent extraction and gas chromatography-mass spectrometry. The yield of crude fatty oil was found to be 45.5% in the mature seeds on dry weight basis. Fourteen compounds, constituting 97.57% of the oil, were identified. The oil was rich in unsaturated fatty acids (70.11%) followed by saturated fatty acids (25.2%). Oleic acid (54.42%), palmitic acid (20.0%), linoleic acid (15.51%), and stearic acid (4.18%) were the main fatty acids in the oil together with four other minor fatty acids. The current study identifies the novel compounds not previously reported in C. paniculatus oil, including 1,4-benzenediol (0.46%), cinnamic acid (0.15%), 2,6-di-tert-butyl-p-benzoquinone (0.03%), butylated hydroxytoluene (0.4%), and eudalene (0.16).
