Effect of Glycerol Concentrations on the Characteristics of Cellulose Films from Cattail ( L.) Flowers.

Plastic waste has become a big problem for the environment globally. Biodegradable polymers are a potential replacement for plastics that can have a positive outcome both environmentally and economically. In this work, we used acid hydrolysis and alkaline treatment to extract cellulose fibers from cattails.

Determination of Wild Grape Phenolic Compounds in the Extracts of Winemaking Byproducts and Their Antioxidant Competency.

<b>Background and Objective:</b> Various medicinal herbs and fruits in Thailand composed of many bioactive phytochemicals, which are support health and reduce the harmful of many diseases. The main objectives of this study were to extract wild grape residues obtained from wine production and fractionate them by silica column chromatography and investigate the chemical substances and antioxidant competency. <b>Materials and Methods:</b> Methanolic crude extract of wild grape pomace was fractionated by silica gel chromatography using the mixture methanol/ethyl acetate as eluting solvents.
