Thus produced colorant will dye cotton fabrics blue. Herein, the properties and dyeing behavior of the colorant from the plant, which is unfamiliar to Japanese, were investigated. The color of the colorant which was rapidly developed from the colorless solution of the leaves was stable to alkali but changed with acid. The color of the solution faded under a sealed condition and reappeared when exposed to air, indicating that the colorant is reduced by some reducing substance in the leaves. However, the colorless precursor in the fresh leaves was found not to be the reduced form of the colorant. A variety of fabrics, including cotton, could be dyed blue to purple with the squeeze of sacatinta. Three colorants were detected from the extract of the dyed fabrics by HPLC analysis.

The fabrication of chitin and chitosan films was investigated is terms of their mechanical properties and biodegradation. The tensile strength of chitin films was 30-40% lower than that of chitosan films, but the crystallinity of chitin film was much higher than that of chitosan films. The crystallinity and orientation of crystallites were hardly affected by the four kinds of solvent chosen to cast chitosan films, but a detailed analysis revealed that the cast film prepared with acetic acid provided slightly lower crystallinity than others. The degradation rate of chitin films by Sphingobacterium multivorum, a kind of decomposition bacteria separated from soil, was higher in comparison with the chitosan films. The degradation rate of chitosan samples prepared with acetic acid was the highest, followed in order by the films prepared with propoinic acid, formic acid and butyric acid. SEM observation revealed that the degradation of chitosan films was followed by exfoliation of chitosan fibrils from the film surface.
