Abstract: The extractives of bamboo leaves were extracted and determined by Py-GC-MS. And the main constituents of extractives were tritriacontane(4.84%), 9-octadecyne(4.19%), ethyl alcohol(3.23%), 2-furanmethanamine, tetrahydro-(3.1%), .beta.-sitosterol acetate(2.84%), vitamin e(2.77%), triacontanoic acid, methyl ester(2.67%), .gamma.-sitosterol(2.33%), pyridine-3-carboxamide, oxime, n-(2-trifluoromethyl -phenyl)-(2.32%), nonacosane(2.15%), etc.

Abstract: In order to evaluate its potential health risk to biomedical engineering, the extractives of Phyllostachys pubescens were adsorbed and determined by Py-GC-MS. And the main constituents were 1-phenanthrenecarboxylic acid, 1,2,3,4,4a,9,10,10a-octahydro-1,4a-dimethyl-7 -(1-methylethyl)-(23.41%), benzofuran, 2,3-dihydro-(3.2%), cyclobutene(2.77%), 1-nonadecene (2.18%), isopropylcyclobutane(2.16%), stigmastan-3,5-diene(2.14%), benzene(2.03%), 1-hexadecene(1.99%), 1,3-butadiene, 2-methyl-(1.81%), glycerin(1.75%), 1-hexene(1.64%), phenol, 4-methyl-(1.55%), 2-methyl-1-butene(1.54%), toluene(1.47%), 1,3-cyclohexadiene(1.29%), heptacosane, 1-chloro-(1.17%), phenol, 4-(2-propenyl)- (1.06%), 1-pentadecene(0.96%), pentane, 3-methylene-(0.95%), etc. So the extractives of Phyllostachys pubescens was safe.

Abstract: In order to find out its potential biomedicines, the extractives of Moso bamboo were adsorbed and determined by Py-GC-MS. And the main constituents were 1-phenanthrenecarboxylic acid, 1,2,3,4,4a,9,10,10a-octahydro-1,4a-dimethyl-7-(1-methylethyl)-, methyl ester(5.68%), glycerin(4.32%), .gamma.-sitosterol(2.53%), benzofuran, 2,3-dihydro-(2.24%), decanoic acid, 1,2,3-propanetriyl ester(2.23%), phenol, 2,6-dimethoxy-(1.93%), stigmast-5-en-3-ol, oleate(1.92%), dodecanoic acid, 1-(hydroxymethyl) -1,2-ethanediyl ester(1.84%), 2-furancarboxaldehyde,5-(hydroxymethyl)- (1.72%), etc.

Abstract: In order to evaluate its potential biomedicines, the extractives of Phyllostachys pubescens were extracted and determined by Py-GC-MS. And the main constituents were 1-phenanthrenecarboxylic acid, 1,2,3,4,4a,9,10,10a-octahydro-1,4a-dimethyl-7-(1-methylethyl)-(% 7.02), stigmast-5-en-3-ol, oleate(4.33%), 4,4,6a,6b,8a,11,11,14b-octamethyl-1,4,4a,5,6,6a,6b,7,8, 8a,9,10,11,12,12a,14,14a,14b-octadecahydro-2h-picen-3-one(3.39%), etc. So the benzene-alcohol extractives of Phyllostachys pubescens could be used for biomedical engineering.

Abstract: In order to find out its active behavior, the extractives of bagasse biomass were adsorbed and determined by Py-GC-MS. And the main constituents were 1-phenanthrenecarboxylic acid, 1,2,3,4,4a,9,10,10a-octahydro-1,4a-di methyl-7- (1-methylethyl)-(52.25%), stigmastan- 3,5-diene (11.3%), 2(1h)-phenanthrenone, 3,4,4a, 9,10,10a-hexahydro-7-hydroxy-1,1,4a-tri methyl-8- (1-methylethyl) - (9.00%), 2- furancarboxaldehyde, 5-(hydroxym ethyl)- (6.25%), etc.
