Optimization of Lignin-Cellulose Nanofiber-Filled Thermoplastic Starch Composite Film Production for Potential Application in Food Packaging.

The optimization of the production of thermoplastic starch (TPS) bionanocomposite films for their potential application in food packaging was carried out, according to the Box-Wilson Central Composite Design (CCD) with one center point, using Response Surface Methodology (RSM) and fillers based on lignin and nanofiber, which were derived from bamboo plant. The effects of the fillers on the moisture absorption (), tensile strength (), percent elongation (PE) and Young's modulus () of the produced films were statistically examined. The obtained results showed that the nanocomposite films were best fitted by a quadratic regression model with a high coefficient of determination () value.

Effect of partially purified sub-fractions of extract on carbon tetrachloride intoxicated rats.

Background: This study was designed to determine the hepatoprotective effect of partially purified fractions from extract on carbon tetrachloride (CCl) intoxicated rats.

Methods: The methanol extract of was subjected to solvent partitioning using n-hexane, chloroform, ethylacetate and water. Separation of fractions with proven antioxidant activity was achieved by chromatographic techniques.
