Analytical Result

The bamboo resource is very abundant in China, and both species and yield of bamboo are the first in the world. In the countryside of China, farmers often used the extractives of bamboo root to cure some special diseases; however, the biomedical constituents of extractives of bamboo root are still not completely explained. Therefore, 450 °C pyrolysis- GC/MS technology was used to identify the top value-added biomedical constituents of root-based benzene/ethanol extractives from the richest bamboo species “Moso bamboo”. After treatment of benzene/ethanol extraction, the extractives obtained was fully pyrolyzed at 450 °C in He atmosphere, and then the 450 °C pyrolyzate obtained was analyzed by online-linked GC/MS. Relative content of each component was determined by area normalization. 59 chemical constituents representing 97.62% were identified from 64 peaks. The analytical result showed that the 450 °C pyrolyzate of benzene/ethanol extractives from Moso bamboo root is abundant in biomedical constituents, and also contains other bioactive components, which can be used as top value-added materials of high-grade cosmetic, food, spice, and chemical. The result will be useful to expedite biomedical development of root extractives, and to provide further scientific foundation for its top value-added application of bamboo resources.

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.

Cinnamomum camphora is a famous non-wood tree, which can be used to extract camphor, C. camphora oil and its ramification. It is an excellent timber tree and evanescence species with the road. Researches about the chemical composition of C. camphora root wood is very less, this restricts the development and utilization of the root of C. camphora. Therefore, we used Py-GC/MS technology to analyze the high-grade resource recovering approaches of C. camphora root wood. After treated with freeze-drying and smashing, samples were extracted by the acetone extraction. After concentration and refrigeration dry, the comminuted power of C. camphora root wood was pyrolyzed in He atmosphere at 750°C, then the pyrolysis product was analyzed by online linked GC/MS. Relative content of each component was determined by area normalization. The analytical result showed that C. camphora root wood can be used as top value-added materials of biomedicine, and also as the materials of bioenergy, perfume, cosmetic, food, dye and industrial solvent.
