Camphor tree is economically important tree species in southern China, and valuable timber species has formed the base for the construction of crude essential oil extraction purification essential oils, essential oil products developed increasingly sophisticated industrial chain, increase in foreign exchange and the promotion of Fragrance Flavor and industrial development is playing an increasingly important role. However, more study of the camphor tree resources development and utilization in China, but not high quality of the camphor tree essential oil, one of the key reasons for the lack of the the Zhangshu whole tree different organs of the chemical composition of the system, which are difficult to gasification of bio-active ingredients. The research has been in the blank. Thus, the different organs of the camphor tree as the research object, obtained through a variety of solvent extracts of different types, for the first time - GC pyrolysis, thermal desorption - GC means combining conventional GC means of the camphor tree chemical composition of different solvent extracts of different organs of the whole tree system analysis, reveal the component characteristics under different temperature conditions and contents variation identified bioactive components, on this basis, the research Zhangshu different organs of various types of extraction The application prospects of the matter, and to provide a scientific basis and technical support for the the Zhangshu whole tree high grade resource utilization of different organs in the field of bio-medicine, perfumes, cosmetics, and other industrial. The main results are as follows: (1) camphor tree extract the GC-MS analysis of the matter. After MS parsing and functional analysis of the identified 15 compounds, the camphor timber benzene / ethanol extracts of 98.72% of the total peak area, the analysis results show that it contains a large amount of camphorsulfonic acid, propionic acid linalyl ester, cineol, safrole, etc.: camphor leaf benzene / ethanol extract identified 29 compounds, for 99.35% of the total peak area, the analysis results showed that in addition to containing a large number of outer cineol, α-terpineol, further containing a total content of up to 12% of the precious spices - ethylenically (α-pinene, sabinene, p-pinene, myrcene, α-terpinene, caryophyllene, α-caryophyllene alkenyl, () - Orange alkenyl, etc. ). (2) the camphor tree extract the pyrolysis - GC-MS analysis. After pyrolysis, MS analysis and functional analysis, camphor tree twigs of benzene / ethanol extracts of 350 ° C Pyrolysates identified 70 compounds, 550 ℃ under 110 compounds were identified, 750 ℃ ??for 76 compounds were identified; camphor leaves benzene / ethanol extracts of the 350 ° C heat cleavage product is identified in the 113 kinds of compounds, 550 ℃ 106 compounds were identified, 750 ℃ ??identified 128 compounds; the Zhangshu fruit benzene / ethanol extracts of 350 ° C. cleavage product under heat to 136 compounds were identified, 550 ℃ identified 201 compounds, 750 ℃ ??identified 161 compounds; the camphor old skin benzene / ethanol extract 350 ° C under Pyrolysates identified 83 compounds, 550 ℃ identified 114 compounds, 750 ℃ ??identified 115 compounds; camphor root bark of benzene / ethanol extracts of 350 ° C for pyrolysis product was identified 64 compounds, 550 ℃ identified 53 compounds, 750 ℃ under identified 53 compounds; the the the camphor tree Nenpi benzene / ethanol extracts 350 ° C pyrolysis product of 73 compounds were identified, 550 ℃ under 116 compounds were identified, 750 ℃ ??for 32 compounds were identified. Camphor tree twigs and composition of the camphor tree leaves were similar under the conditions of 350 ° C, esters, hydrocarbons, more nitrogenous ingredients, and ethers, terpenes, phosphorus-containing sulfur, less heterocyclic component; 550 ° C conditions, esters , hydrocarbons, other types of ingredients more, ethers, carboxylic acids, heterocyclic, phosphorus-containing sulfur-based component is less; under conditions of 750 ° C, hydrocarbons, other classes content more, and ethers, terpenes, carboxylic acid, a nitrogen class of phosphorus-containing sulfur content of less. Camphor fruit benzene / ethanol extracts of the different temperature pyrolysis product, under the conditions of 350 ° C, hydrocarbons, esters, carboxylic acids, ethers, more nitrogenous component, and the phosphorus-containing sulfur and other heterocyclic aldehydes and copper-based component less; under conditions of 550 ° C, a hydrocarbon, an ester, a carboxylic acid component, nitrogenous more ether, terpene phosphorus sulfur, other types of ingredients less; under conditions of 750 ° C, hydrocarbons, carboxylic acids, esters, nitrogen-containing more class content, and ethers, terpenes, and the phosphorus-containing sulfur, the other class of content is less. Camphor old skin benzene / ethanol extracts of different temperature pyrolysis product, under conditions of 350 ° C, hydrocarbons, esters, carboxylic acids, alcohols, phenolic components more ethers, phosphorus-sulfur, and other component, heterocyclic less ; under conditions of 550 ° C, hydrocarbons, esters, carboxylic acids, alcohols, phenolic components more and ethers, terpenes, phosphorus-containing sulfur component, heterocyclic less; under conditions of 750 ° C, hydrocarbons, esters, carboxylic acids, alcohols and phenols more class content, and ethers, terpenes, less the content of the phosphorus-containing sulfur, the heterocyclic component. Camphor root bark of benzene / ethanol extracts of different temperature thermal cracking product, under the conditions of 350 ° C, hydrocarbons, alcohols and phenols, nitrogen-containing component, heterocyclic more, and ethers, esters, carboxylic acids, other types of ingredients less; under the conditions of 550 ℃, hydrocarbons, carboxylic acids, alcohols and phenols, heterocyclic, more other types of ingredients, and ethers, terpenes, less phosphorus-containing sulfur-based component; under conditions of 750 ° C, hydrocarbons, carboxylic acids, alcohols and phenols, a heterocyclic more class content, and ether, ester, terpene, the less content of other types of components. Different temperature pyrolysis product The camphor Nenpi of benzene / ethanol extract, under conditions of 350 ° C, hydrocarbons, alcohols, phenols, esters, terpenes, and other ingredients, more ethers, phosphorus-sulfur, aldehyde and ketone component less ; under conditions of 550 ° C, hydrocarbons, alcohols and phenols, terpenes, heterocyclic, and other types component more, and ethers, phosphorus-containing sulfur component, carboxylic acids less; under conditions of 750 ° C, hydrocarbons, nitrogen-containing, heterocyclic, and other Classes component more, and ethers, esters, terpenes, less phosphorus-containing sulfur, aldehyde and ketone components. (3) the Zhangshu volatile substances thermal desorption - GC-MS analysis. After thermal desorption, MS parsing and functional analysis, camphor tree branches helium volatiles 40 ° C under thermal desorption products identified 49 compounds, 60 ℃ for 50 compounds were identified, 80 ℃ under 58 compounds were identified ; camphor branches different temperature thermal desorption products, hydrocarbons, terpenes, other component, heterocyclic more content, the carboxylic acid, a nitrogen, phosphorus, sulfur, and esters component content is very small; at 40 ° C, 60 ° C, 80 ℃ temperature rise, alcohols and phenols, aldehydes and ketones, and other types of content gradually increased, terpenes and other type of content gradually reduce hydrocarbon, ester type ingredients \other and other types of content as \This article's analysis test and functional analysis of the results showed that the the Zhangshu different organs resource for the development of high quality spice flavors, expensive medicines, food additives, cosmetics, special industrial raw materials and high value-added products.
