    摘要: A composition for modification of wood products is disclosed. The composition contains a prepolymer formed by the reaction of a polyfunctional hydrophilic polymer of high molecular weight and a crosslinking agent. The composition may also contain a prepolymer formed by the reaction of a sugar and a crosslinking agent. Modification of the wood product may result in one or more of: improved stiffness, strength, surface hardness, dimensional stability, water resistance, flame retardancy, and biological resistance.

    摘要: A method is described for producing an extract of Phyllanthus comprising the steps of: (a) extracting Phyllanthus components with a solvent; (b) fractionating the extract obtained in the preceding step on the basis of hydrophobicity; (c) collecting and combining fractions that correspond in hydrophobicity to elute fractions resulting from 10-50% methanol elution steps, wherein the elute fractions are obtained by low pressure vacuum liquid chromatography (VLC) using a C18 reversed-phase lipophilic column and a water/methanol gradient system, wherein the gradient system is based on an initial elution step of loading the column with 100% water, on intermediate elution steps with gradually decreasing water content and on a terminal elution step loading the column with 100% methanol; and (d) optionally drying the extract obtained in step (c). The invention also relates to an extract of Phyllanthus obtainable or obtained by the method or a fraction thereof and a Phyllanthus extract or fraction thereof comprising repandusinic acid, wherein the repandusinic acid is present at a concentration of at least 42 mg/g.
