Identification of volatile organic compounds of some Trichoderma species using static headspace gas chromatography-mass spectrometry
Fungi release wide spectrum of volatile organic compounds (VOCs) that belong to several chemical groups with different biochemical origins such as monoterpenes, sesquiterpenes, alcohols, aldehydes, aromatic compounds, esters, furans, ketones, sulfur and nitrogen compounds. Trichoderma species are the most studied fungal biocontrol agents and are successfully used as biofungicides and biofertili...
متن کاملAnalysis of volatile compounds in Aucoumea klaineana oleoresin by static headspace/gas chromatography/mass spectrometry
Static headspace analysis of Gabon Estuary okoume (Aucoumea klaineana Pierre) oleoresins indicated that nine products represented the major part (>96%) of the volatile compounds: six monoterpenes (α-pinene, β-pinene, limonene, α-phellandrene, β-phellandrene, 3-carene), one monoterpenic alcohol (α-terpineol) and two other derivatives (p-cymene, eucalyptol). The relative amount of each product ap...
متن کاملComparison of Static and Dynamic Headspace for Volatile Organic Compounds in Orange Juice
The determination of VOCs is widely used in many fields of chemistry. Two common sample preparation techniques for this analysis are static and dynamic headspace. Static headspace is a relatively simple sampling method that is dependent upon the formation of equilibrium conditions in a closed system. Dynamic headspace continually sweeps the headspace of the sample concentrating the analytes ont...
