Evaluation for Diuretic Activity of Abutilon indicum and Amaranthus spinusus Leaves Extracts
Abstract: The diuretic activity of Abutilon indicum and Amaranthus spinusus leaves was studied. The fractions of ethanol and methanol showed significant increase in the urine elimination, while ethyl acetate fraction does not show diuretic activity. All the groups were compared to the control group; frusemide was used as reference standard drug in this screening activity. The phytochemical screening study showed the presence of flavonoids, saponins, terpenoids, and steroid content in both …

High-Performance Biodegradable Films from Bamboo Derived Cellulose Nanofibers and Silk Fibroin: Engineering Sustainable Polymer Composites
Abstract: This research presents the advancement of biodegradable composite films from cellulose nanofibers (CNFs) extracted from bamboo and silk fibroin (SF) derived from Bombyx mori cocoons. CNF/SF composites were fabricated in three different compositions—CS10, CS30, and CS50—via aqueous blending and solution casting, followed by ethanol-induced β-sheet stabilization. Mechanical testing confirmed a considerable enhancement in tensile strength from 72 MPa (CS10) to 112 MPa (CS50), while Young’s modulus improved from 2.4 GPa …
