Six ethanolic extracts, obtained from anise, fennel, lavender, sage, mint, white horehound and their mixture were directly applied onto cellulose (viscose) fabric to impart antimicrobial and antioxidant functionality for its potential use as a wound dressing. Antimicrobial activity of treated fabrics against gram-positive bacteria S. aureus and yeast C. albicans, as common skin pathogens, was determined by agar diffusion test. The most effective against both microorganisms was viscose with anise, fennel, and mint, whereby clear inhibition and suppression zones were detected. The oxidation of viscose, intended to improve sorption properties and consequently adsorption of extracts, increased the antimicrobial activity of viscose with a mixture of extracts. The antioxidant activity of fabric samples with extracts, determined by 2,2-Diphenyl-1-picrylhydrazyl (DPPH) assay, was significantly higher when compared to the untreated viscose sample (2.38 %) and ranged from 11.82 % for viscose with fennel up to 87.71 % for viscose with sage. Oxidation of fabric before sorption of extracts mixture contributes to higher antioxidant activity (68.81 %). Direct impregnation of bioactive plants extracts onto the fabric represents low cost and simple method, which makes it suitable for obtaining eco-friendly, low-cost disposable medical textiles with the therapeutic and prophylactic role.

精选芳香植物提取物作为纤维素织物的抗菌和抗氧化整理剂 - 直接浸渍法

从茴香、茴香、薰衣草、鼠尾草、薄荷、白苦苣及其混合物中提取的六种乙醇提取物直接应用于纤维素(粘胶)织物上,以赋予其抗菌和抗氧化功能,使其有可能用作伤口敷料。处理过的织物对革兰氏阳性菌金黄色葡萄球菌白色念珠菌的抗菌活性,作为常见的皮肤病原体,通过琼脂扩散试验确定。对这两种微生物最有效的是含有茴香、茴香和薄荷的粘胶,由此检测到明显的抑制区和抑制区。粘胶的氧化旨在提高吸附性能并因此提高提取物的吸附性,增加了粘胶与提取物混合物的抗菌活性。与未经处理的粘胶样品 (2.38 %) 相比,含提取物的织物样品的抗氧化活性通过 2,2-二苯基-1-苦基肼 (DPPH) 测定法测定显着更高,范围为 11.82 %(含茴香的粘胶) 87.71 % 粘胶与鼠尾草。在提取物混合物吸附之前织物的氧化有助于提高抗氧化活性 (68.81 %)。
