Chinese Hackberry (Celtis sinensis) 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 Chinese Hackberry were mostly focused on the biomass analyses and utilizations of its wood, and lacked those to analyze the chemical components of extractives of Chinese Hackberry leaves, which was very important to recover and utilize the polluting waste Chinese Hackberry leaves. Therefore, the chemical components of benzene/ethanol extractives of Chinese Hackberry leaves were analyzed by method of GC/MS in order to identify top value-added bioactive components from waste leaves of Chinese Hackberry tree. The analytical result showed that the main components of benzene/ethanol extractives of freeze-dried Chinese Hackberry leaves by GC/MS analysis were identified 10 components (106 peaks) as: Sesquirosefuran (48.57%), Thiophene, 2-ethyltetrahydro- (20.01 %), Hexatriacontane (8.67%), Octadecane (8.60%), 1-Eicosanol Pregn-4-en-3-one, 20-hydroxy-, (20R)- (4.52%), 1-Amino-2-(hydroxymethyl)anthraquinone (3.63%), 1,3-Diphenyl-(4H)1,2,4-triazoline- (1.92%), Tricyclo[4.3.1.13,8]undecane-1-carboxylic acid (1.69%), Eucalyptol (1.60%), etc. As the first report here, our result by GC/MS showed that the benzene-methanol extractive of freeze-dried Chinese Hackberry leaves can be developed into top value-added materials of spicery, biomedicines, and biofuel.

A preliminary chemical characterization of main components of ethanolic extract with dried rhizomes of Smilax domingensis Wid. that grow in Cuba was done using a GCMS-QP2010 Ultra Shimadzu and the mass spectra of the compounds found in the extract was matched with the National Institute of Standards and Technology (NIST) library. After sample derivatization 125 chemical compounds were registered by the equipment and from them, 35 different chemical components were characterized and reported for the first time from this part of the plant in our country. The results demonstrate the developed method could be employed as a rapid and versatile analytical technique for identification of chemical constituents and quality control of Smilax domingensis.
