Determination of Bioactive Components of Waste Leaves from Chinese Hackberry by GC/MS
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)l,2,4-triazoline-(1.92%),Tricyclo4.3.1.13,8undecane-l-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.
