Determination of Chemical Components of Benzene/Ethanol Extractives of Phyllostachys heterocycla slub by Py-GC/MS

摘要：

The increasing demand for paper in Asia is being met by the use of Phyllostachys heterocycla to a large extent.However,some pulp mills may be forcedly closed because the Phyllostachys heterocycla chips contain extractives severely enough to pollute the water.In this paper,the chemical components in the benzene/ethanol extractives of fresh Phyllostachys heterocycla slub were isolated and identified by Py-GC/MS.The relative content of each component was determined by peak area normalization.66 compounds in the extractives were identified.The mainly abundant constituents were stigmasterol(9.07％),trimethylamine(8.47％),phenol,2,6-dimethoxy-(7.93％),phenol,3-(1-methylethyl)-(5.5％),n-hexadecanoic acid(5.2％),2-methoxy-4-vinylphenol(4.95％),9,12-octadecadienoic acid(Z,Z)-(4.56％),phenol,2,6-dimethoxy-4-(2-propenyl)-(4.48％),2,4,7(1H,3H,8H)-pteridinetrione (3.95％),phenol,2-methoxy-(3.21％),benzofuran,2,3-dihydro-(2.79％),9,12,15-octadecatrienoic acid,methyl ester (2.42％),glycine,N,N-dimethyl-,methyl(1.88％),DL-proline,5-oxo-,methyl ester(1.84％),phenol,2-methoxy-4-(1-propenyl)-,(E)-(1.65％),octadecanoic acid(1.44％),benzene,4-ethenyl-1,2-dimethoxy-(1.29％),phenol,2-( 1-methylethyl)-(1.24％),1,6,10-dodecatrien-3-ol,3,7,11-trimethyl-(1.19％),and so on.The most components from benzene/ethanol extractives of fresh Phyllostachys heterocycla slub are not only abundant and healthy to human,but also can be used as fine bioenergy.
