Abstract:The volatile oil and fatty acids in Screw-pine, a kind of mangrove plants, were determined by GC-MS in this paper. The result indicates that 76 peaks was shown in the chromatogram of the volatile oil extracts in Screw-pine and 60 compounds were identified from the volatile oil extracts of Screw-pine, among which butylated hydroxytoluene had the highest content (19.25%). Benzeneacetic acid, hexadecanoic acid, hentetracontanol, 2-isoproryl-5-methyl-1-hexanol, docosanol, decyl ether, hexacosanol and their isomers were also found in the extracts of the volatile oil. 22 peaks were shown in the chromatogram of the extracts of the fatty acids in Screw-pine and 6 compounds were identified, among which hexadecanoic acid content was as high as 35.39%. Contents of stearic acid and oleic acid were 18.88% and 10.03%, respectively. Two isomers of tetradecanoic acid were found. Further research on the utilization of main constituents from volatile oil and fatty acid of Screw-pine was recommended.
