    Chemical Components of Teak Wood with Eccentric Growth by Ganis Lukmandaru

    Published 2011-01-01
    “…Data analysis by paired t-test showed that no significant difference was found between the upper and lower parts in ethanol-benzene extractive content (4-12%), hot-water soluble content (1-3%), ash content (0.73%) and acid soluble lignin content (0.7-1.4 %) . By means of Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC-MS), no striking difference was also observed in the levels of major components of ethanol-benzene extracts. …”
