The present study is aimed at evaluating the antibacterial and antioxidant properties of bael fruit shell (BFS) extract. Hot water extraction (HWE) and ultrasonic assisted extraction (UAE) techniques have been used to understand the effectiveness of the extraction process and its relation to impart enhanced functional property of cotton fabric. The cotton fabric has been treated with BFS extract by using padding mangle. The effectiveness of antibacterial activity against both the Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria and antioxidant property has been evaluated both qualitatively and quantitatively. The results reveal that UAE-BFS treated fabric shows 93% reduction for E coli and 82% for S aureus, which is higher as compared to HWE-BFS treated fabric (91% for E coli and 61 % for S aureus). This trend has also been observed in qualitative zone of inhibition method. Antioxidant efficacy of UAE treated fabric is 86%, whereas HWE treated fabric registers 80% activity.

贝尔果壳提取物处理棉织物的体外抗菌和抗氧化活性

本研究旨在评估贝尔果壳 (BFS) 提取物的抗菌和抗氧化特性。热水提取 (HWE) 和超声波辅助提取 (UAE) 技术已被用于了解提取过程的有效性及其与增强棉织物功能特性的关系。棉织物已通过使用浸轧法用 BFS 提取物进行处理。已对革兰氏阳性（金黄色葡萄球菌）和革兰氏阴性（大肠杆菌）细菌的抗菌活性和抗氧化性能进行了定性和定量评估。结果表明，UAE-BFS 处理的织物显示出大肠杆菌减少 93% 和金黄色葡萄球菌减少 82%，与 HWE-BFS 处理的织物（大肠杆菌减少 91%，金黄色葡萄球菌减少 61%）相比，这一数字更高。在定性抑制区法中也观察到了这种趋势。阿联酋处理织物的抗氧化功效为 86%，而 HWE 处理织物的活性为 80%。
