Study on Chemical Compositions and Elements of Artocarpus Heterophyllus Lam Wood
The chemical compositions of Artocarpus heterophyllus Lam wood were investigated and content of trace elements in wood were determined. The result showed that the chemical compositions of Artocarpus heterophyllus Lam wood are as following: ashes 15.5 g•kg-1, cold water extraction 35.2 g•kg-1, hot water extraction 55.1 g•kg-1, 1%NaOH extraction 157.7 g•kg-1, benzene-alcohol extraction 79.2 g•kg-1, sodium nitrate-alcohol cellulose 467.6 g•kg-1, holo-cellulose 709.8 g•kg-1, pentosan 212.6 g•kg-1,Acid-soluble lignin 44.9 g•kg-1, Acid insoluble lignin 237.4 g•kg-1, Organic solvent soluble lignin 248.3g•kg-1, Phenolic hydroxyl content of organic solvent soluble lignin 0.25 mmol•g-1; the content of 12 trace elements in Artocarpus heterophyllus Lam wood are: Fe 959μg.g-1, Mn 9.37μg.g-1, Cu 5.60μg.g-1, Zn 17.1μg.g-1, Ca 2.26 mg.g -1, Mg 433μg.g-1, Na 28.1μg.g-1, K 1.05 mg.g-1, Al 46.2 μg.g-1, Pb 0.603 μg.g-1, Cd and Ni were not detected.
