-
The essential oil from Malania Olceifera Chum was extracted by steam distillation,and the chemical components were identified and determined by gas chromatography-mass spectrometry (GC-MS) method.The results show that the yield of essential oil was 1.3% from peel and flesh of Malania Olceifera Chum,and 6 compounds (99.37%) of 10 chromatographic components in the oil were identified.The major constituents include benzaldehyde (78.79%),benzyl alcohol (14.69%),mandelonitrile (4.74%),benzoic acid (0.15%),benzyl benzoate (0.12%),α-cyanobenzyl benzoate (0.88%).The yield of oil extracted from the branches and leaves was 0.3%,which contains 6 chromatographic components and 4 compounds (99.6%) in that were identified,the major components were benzaldehyde (61.88%),benzyl alcohol (1.51%),mandelonitrile (24.80%) and benzoic acid (11.32%).The yield of benzaldehyde was 80.8%,purity was 98% by vacuum rectification in N2.
