GC-MS Analysis on Heartwood Extractive Chemical Components of Different Provenances Teak（Tectona Grandis L.f.）
Teak (Tectona grandis L.f) is decay resistance and natural durability. These advantages are relationship with inclusion of teak. For breeding, planting, and the wood used to its best advantage by the end-user, further information concerning the heartwood extractive chemical of different provenances teak is necessary, However, because of limitation of analytical instruments, the extractive chemical components of teak centre on decay resistance relationship with napthoquinone, tectoquinone, and so on, nobody systematacially analyzed heartwood extractive chemical components of different teak. We analyzed and contrasted extractive chemical components of three provenances teak heartwood(Indian, Thailand and Nigeria), and found 109 peak and 74 compounds was identified, the same compounds of 3 provenances were 27. The main compounds were Mequinol, 1,2-benzenediol, 1(3H)-Isobenzofuranone, Vanillin, 1,4-Naphthalenedione, Naphthalene, 1,2,3,4,4a,5,6,8a- octahydro-7-methyl-4-methylene-1- (1- methylethyl), Cyclohexane, 1-ethenyl-1-methyl- 2-(1-methylethenyl)-4- (1- methylethylidene)-, 4,6-Dimethoxysalicylaldehyde, 2-Propenal, 3-(1,3-benzodioxol-5-yl)-, 4-((1E)-3-Hydroxy -1-propenyl) -2-methoxyphenol, 1H-Imidazole, 1-ethyl-, 2-Methylisoborneol, Phthalic acid, phenyl 2-pentyl ester, 1,4-Naphthalenedione, 2-hydroxy-3-(3-methyl-2-butenyl)-, [1,1'-Biphenyl]-2-ol, 5-(1,1-dimethylethyl)-, 9,10- Anthracenedione, 2-methyl-, 1-Hydroxy-4-methylanthraquinone, Indane-1,3-dione, 2-(3-hydroxyphenyl)- 2H-Benzopyran - 2-one, 4-methyl-3-phenyl-, 9,10-Anthracenedione, 1,8-dihydroxy-2-methyl-, 2-(Hydroxymethyl) anthraquinone, 4H-1-Benzopyran-4-one, 3-hydroxy-2-phenyl-, Benzofuran-3-one, 2-[3-hydroxy-4-methoxy benzylidene] -6-hydroxy-, Squalene, .gamma.-Sitosterol, 9,19-Cyclolanost-24-en-3-ol, (3.beta.)-, Cholest-8(14)-en-7-one, (5.alpha.)-.
