Studies on Extraction, Modelling and Purification of Quercetin from Peel of Allium cepa
Abstract: ABSTRACT Quercetin is an anti-oxidant, which very efficiently scavenges highly reactive biological species such as peroxynitrite and hydroxyl radical. Quercetin belongs to the flavonoid’s family. The present studies on optimization of physico-chemical parameters like effects of different solvents, different solvent percentages, particle size, pH and extraction time for the extraction of quercetin was studied. The highest quercetin concentration for optimized conditions was 38 µg/ml. In the soxhlet extraction process, the …

Optimizing Dyeing Processes for Nylon: A Study onUltrasonic and Natural Dye Application
Abstract: This study focuses on the application of natural dyes, specifically those derived from onion (Allium cepa) extracts, for dyeing nylon fabric, while assessing the impact of different mordants, including potassium dichromate, copper sulfate, and alum. The research explores the effectiveness of High Temperature High Pressure dyeing techniques to enhance dye uptake and color fastness. Natural dyes, traditionally viewed as less effective than synthetic counterparts, are being reevaluated for their eco-friendly …
