The yield and chemical composition of the seed oil ofCelastrus paniculatuswere 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 inC. paniculatusoil, 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).

The yield and fatty oil components of the seed kernels ofAnnona squamosaLinn. (Family: Annonaceae) were determined by a solvent extraction method and gas chromatography--mass spectrometry (GC/MS). The seed kernels were found to contain about 22.2% of crude fatty oil on a dry weight basis. The crude fatty oil was converted into methyl esters and analyzed by GC/MS. Eleven compounds, constituting 99.8% of the oil, were identified and the main compounds were oleic acid (47.4%), linoleic acid (22.9%), stearic acid (13.6%), and palmitic acid (12.1%). Oleic acid and linoleic acid together constitute 70.3% of the unsaturated fatty acids (UFAs) followed by the saturated fatty acids (25.7%), mainly palmitic acid and stearic acid. Heneicosanoic acid (2.3%), 11-eicosanoic acid (0.2%), 17-methyloctadecanoic acid (0.1%), and dihydrostereculic acid (0.1%) have not been reported earlier from the oil ofA. squamosabut were found in this study.
