Walnut shell is chemical element

    Through the chemical components of walnut is systematically studied. The main components of walnut wood grain, cellulose and hemicellulose, compared with other plants, cold, hot water content, 1% Na-OH drawn out things, don't dissolve acid content of lignin were higher, the fiber content significantly lower, more pentosan content and similar broadleaf timber. Different origin of walnut SSC bubble walnut, the chemical compositions of the difference, but the main composition is insoluble lignin acid. Walnut is C, H main elements, O, N, S, etc, and contain calcium, magnesium, iron, silicon, phosphorus and other trace elements.
   Walnut wood grain for GS model (the guaiac-based base-lilac base type) wood grain, among them with G unit is given priority to, and contain more 7-hydroxy.
