Chemical compositions and functions of Chinese fir volatiles

Abstract

Chinese fir is an important economic tree species in China. In addition to the application of alive trees and wood, the abundant chemical compositions of Chinese fir as a non-wood resource also have very important position. This study used Chinese fir wood powder as material, analyzing the chemical composition of Chinese fir volatiles by Fourier transform infrared spectroscopy (FT-IR), thermogravimetry (TG), pyrolisis-gas chromatography-mass spectrometry (Py-GC-MS), thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS). Through the analysis of the detected we can know that volatiles main were phenolic (cedrol, alpha-bisabolol and beta-eudesmol), ester (dimethyl phthalate, diisobutyl phthalate and dibutyl phthalate), ketone (hydroxyacetone and benzofuran) and aldehyde (hexanal and nonanal) and so on. This compounds and their derivatives can use at wide medical, biology, cosmetics and textile industry.

Development of Microcapsule Bioactive Paper Loaded with Chinese Fir Essential Oil to Improve the Quality of Strawberries

“…Most of the research on CFEO has focused on the analysis of the mechanisms underlying its antibacterial activity, but applications are rarely reported. The raw material for CFEO-Chinese fir (Cunninghamia lanceolata)-is an essential commodity in China that is widely used in construction, bridges, shipbuilding, furniture and appliances [13][14][15][16]. There is no research on the use of CFEO in food packaging paper, an area for which CFEO has the potential to be used as a natural preservative in packaging materials for food preservation in the future; however, CFEO applications have been restricted by its limitations, which include insolubility in water, poor stability, volatilization and oxidation [17]; therefore, there is an urgent need to explore solutions to the above limitations to expand the application of CFEO in food packaging.…”
