Abstract: Platanus × acerifolia (Ait.) Willd has high tolerance to environment stress, and a long history of utilization and plantation in China. It is important to recover and utilize the polluting waste leaves from Platanus × acerifolia (Ait.) Willd in order to separate top value-added bioactive components, hence the chemical components of benzene/ethanol extractive of waste leaves from Platanus × acerifolia (Ait.) Willd by means of GC/MS. Relative content of each component was determined by area normalization, and 19 compounds representing 92.35 % of the extractives were identified. The most abundant constituents were as: The analytical result showed that the main components of benzene-methanol extractive of freeze-dried waste leaves from Platanus × acerifolia (Ait.) Willd by GC/MS analysis were 1,3-Dioxane (24.95%), Ethylbenzene (19.03%), p-Xylene (16.02%), Benzene, 1,2-dimethyl- (6.64%), Indane (4.00%), Heptanal (3.89%), 1-Methyl-2-(4-nitrophenyl)benzimid (3.39%), (11H)Pyrido[3',2':4,5]imidazo[2,1- (3.25%), 10-Methylnonadecane (3.00%), Benzene, 1-ethyl-3-methyl- (2.91%), Benzene, 1-ethyl-3-methyl- (2.65%), Benzene, 1-ethyl-2-methyl- (2.46%), 2,5-Cyclohexadien-1-one, 2,5-dimethyl- (1.74%), Docosane, 7-butyl- (1.52%), 1-Amino-2-(hydroxymethyl)anthraqui (1.47%), Acetaldehyde - (0.89%), etc. Our result by GC/MS firstly showed that the benzene-methanol extractives of freeze-dried waste leaves from Platanus × acerifolia (Ait.) Willd can be used as top value-added materials of medicines, cosmetics and industrial solvents.

Abstract: Rosewood tree has high adaptability to environment and tolerance to water stress, and a long history of utilization and plantation in many countries. However, researches on Rosewood were mostly focused on the biomass analyses and utilizations of its wood, and lacked those to analyze the chemical components of extractives of Rosewood leaves, which was very important to recover and utilize the polluting waste Rosewood leaves. Therefore, the chemical components of benzene/ethanol extractives of Rosewood leaves were analyzed by method of GC/MS in order to identify top value-added bioactive components from waste leaves of Rosewood tree. The analytical result showed that the main components of benzene/ethanol extractives of freeze-dried Rosewood leaves by GC/MS analysis were identified 16 constituent (16 peaks) as: Ethanol, 2-butoxy- (40.36%), 2-O-Methyl-D-mannopyranosa (18.22 %), Hydrazine, 1,1-dipropyl- (6.09%), 1-Docosanol (5.59%), 1-Eicosanol (5.28%), Oxirane, hexadecyl- (3.63%), trans-2,4,5-Trimethoxy-.beta.-methyl- (3.50%), Bicyclo[3.1.1]heptane, 2,6,6-trimethyl- (2.53%), 9,12,15-Octadecatrienoic acid, methyl- (2.43%), Tetratetracontane (2.31%), Hexadecane, 1-(ethenyloxy)- (2.27%), Cholan-24-oic acid, 7,12-bis(acetyloxy)-3-ethoxy-, methyl ester, (3.alpha.,5.beta.)- (2.10%), Hexatriacontane (2.02%), Phytol (1.76%), Octadecane, 1-chloro (1.08%), etc. As the first report here, our result by GC/MS showed that the benzene-methanol extractive of freeze-dried Rosewood leaves can be developed into top value-added materials of medicines, biofuel, and industrial solvents.

Abstract: In order to separate top value-added bioactive components from waste leaves of Phoenix tree and hence decrease its pollution to water environment, we attempted to analyze the chemical components of benzene/ethanol extractive of Phoenix leaves by means of GC/MS. Relative content of each component was determined by area normalization, and 10 compounds representing 94.37 % of the extractives were identified. The most abundant constituents were as: Ethanol, 2-butoxy- (47.49% from two peaks), exanoic acid, ethyl ester (22.89%), 1-Butyne, 3-chloro- (17.04%), Bicyclo[3.1.1]heptane, 2,6,6-trimethyl- (3.17%), cis-2,3,5-Trimethoxy-.beta.-methyl- (2.91%), Cyclohexanone, 3-hydroxy- (2.20%), 2,5-Cyclohexadien-1-one, 2,5-dimethyl- (1.35% from two peaks), cis-11-Hexadecen-1-yl acetate (1.04%), Octadecane (1.00%), etc. As the first report here, our result by GC/MS showed that the benzene-methanol extractive of freeze-dried Phoenix leaves can be developed into top value-added materials of medicines, biofuel and solvents.
