Abstract

Clove (Syzygium aromaticum) is one of the useful herbal medicine to prevent the bacteria infection. This herbal medicine plant shows high antimicrobial, antioxidant, and anti-inflammation activities because the essential oil and extract of this herb contains a rich source of phenolic compounds. The important phenolic compound of the herb is eugenol. In this study, we endeavored to develop the flexible cellulosic textile nanocomposite by dipping the cellulosic textile in a nano emulsion containing clove herbal medicine (32%wt). This nanocomposite was subjected to detail analyzes using Fourier Transform Infrared Spectroscopy (FTIR), field-emission scanning electron microscope (FESEM) and gas chromatography-mass spectrometry (GC-MS). The mean size of this nano emulsion as measured by electron microscopy is between 100 and 300 nm. The presence of eugenol in this nano emulsion has been confirmed by GC-MS. The wound dressing shows high antimicrobial activity against E. coli (3 ± 0.11 mm), P. aeruginosa (2.8 ± 0.06 mm), S. epidemidis (2.9 ± 0.09 mm), and S. aureus (2.6 ± 0.07 mm). This nano composite showed significant improvement in in vivo wound healing and in vitro cellular compatibility. Nearly 85% of the operation wound was healed during14 days. Accordingly, cellulosic textile/clove wound dressing can be a potential candidate for biomedical application and pre-clinical surveys.

摘要

丁香(Syzygium aromaticum)是一种有用的草药,可以预防细菌感染。这种草药植物表现出很高的抗菌、抗氧化和抗炎活性,因为这种草药的精油和提取物含有丰富的酚类化合物。这种草药的重要酚类化合物是丁香酚。在这项研究中,我们试图通过将纤维素纺织品浸入含有丁香草药的纳米乳液(32wt%)中来开发柔性纤维素纺织品纳米复合材料。使用傅里叶变换红外光谱(FTIR)、场发射扫描电子显微镜(FESEM)和气相色谱-质谱联用(GC-MS)对这种纳米复合材料进行了详细分析。电子显微镜测量的这种纳米乳液的平均粒径在 100 到 300nm 之间。GC-MS 证实了纳米乳液中丁香酚的存在。这种伤口敷贴具有很高的抗菌活性,对大肠杆菌(3±0.11mm)、绿脓假单胞菌(2.8±0.06mm)、表皮葡萄球菌(2.9±0.09mm)和金黄色葡萄球菌(2.6±0.07mm)都有效。这种纳米复合材料在体内伤口愈合和体外细胞相容性方面都有显著的改善。在 14 天内,近 85%的手术伤口得到了愈合。因此,纤维素纺织品/丁香伤口敷贴可能是生物医学应用和临床前研究的潜在候选材料。
