The Research Of The Biochemical Type And Selecting Excellent Trees Of The Essential Oil Of Cinnamomum Camphora (L.) In Fujian Province, China

There is tremendous preponderance in the essential oil resources of Cinnamomum camphora (L) in Fujian province, China. But because the resources uncultivated quality and the primordial exploitation bring it disadvantage seriously. In view of the situation, if we want to come into a new phase in exploiting camphor oil, we must choose the unmixed biochemical plant as the matrix, and research the asexual reproduce means(culturing tissue) and build artifical camphor woods. By means of the brushwood management, we can produce the highly pure linalool, camphors cineol and other essential contents-Large numbers of camphor tree essential oil in Fujian province is gathered and analyzed. The advantaged geography and climate condition is very fit for breeding the woods for the essential oil of camphor tree.There are very rich resources of essential oil in the camphor tree in Fujian province, after analyzing the component of the essential oil by the gas chromatography in the whole province. The essential oil includes linalool, cineol, camphor, safrole, a-pinene and so on. I also found that the high value linalool dominates in the essential oil in Fujian province, but the content variation of single plant is great.Eight kinds of elements in essential oil in the camphor tree in Fujian province are confirmed: camphene, a-pinene, cineol, linalooK camphor, terpinene, nerol and safrole, with the help of gas chromatogram machine and the expert advice. By the primary component analysis, Four primary components to govern above-mentioned 8 chemicals are distilled. The camphene, cineol, and a-pinene burden larger loading factors in the first main component. The terpinene and nerol burden larger loading factors in the second main component, safrole burden larger loading factors in the third main component. The camphor burdens larger loading factors in the forth main component.The essential oil of camphor tree in Fujian province is quantitatively evaluated, through the primary component analysis. After gotten scores on each primary component, the clustering analysis is made. The between-groups linkage clustering method and the squared Euclidean distance are adopted in the process of the clustering analysis. According to 505 groups of gas chromatography analysis table, The Fujian camphor tree is divided into four biochemical types: the linalool types the cineol type, the camphor type and the salrole type, separately calling the four types of tree as the linalool tree, the cineol tree, the camphor tree and the safrole tree. The clustering result is 34 cineol trees, 425 linalool trees , 10 camphor trees and 19 safrole trees .The aim of clustering is to choose excellent camphor trees. The result of clustering and 505 groups of gas chromatography analysis table is the database of choosing the excellent camphor trees. On the basis of choosing the excellent camphor trees, according the average content and standard deviation of each enssential oil, the classification standard is made. The exceedingly high level: cineol content>60%, linalool content>80%,camphor content>75%,and safrole>60%. Then I made the average.low andexceedingly low levels.On the basis of the hierarchical standard, considering the oil content rate, the excellent trees are selected on each camphor tree essential oil. When selecting the excellent cineol tree, the standard is the oil content rate and cineol containing rate=118. Selecting 6 trees: U14,4, U6, U2, 126, 47. When selecting the excellent linalool tree, according the rate linalool containing rate=95% and the camphor containing rate=O.6%, selected 11 trees: 120, 187, 195, 209, Puchengl, Puchengl3, Puchengl4, Puchengl5, Puchengl6, Pucheng2. When selecting excellent camphor trees, the product of the oil content rate and the camphor containing rate=100, selected 4 trees: Yong'an28, 242, 80, Shunchang7. When selecting the excellent safrole tree, according the product of the oil content rate and the safrole containing rate=37, selected 3 trees: Zhangzhoul, Xiamen2, Xiamenl.The geographical distribution and monthly distribution of the essential oil of camphor tree is reviewed in Fujian province. Considering the oil contentrate, the essence containing rate and the percentage of the specific essence in the each essential spices, the oil yield and the linalool percentage of the linalool spices both are bigger in the cross area of J3 and Wl > W3. We can exceedingly probably select the excellent cineol spices in the cross area of J2 and W3, the excellent camphor spices in the cross area of J2 and W2> W3, the excellent safrole tree in the cross area of J4 and W6.By means of analyzing the monthly distribution of the camphor tree's essence, we can come into the conclusion that we can get the largest linalool harvest yield on May or July without regarding to the biomass factor, and the largest cineol harvest yield on April and the largest camphor harvest yield on May .
