(CC) is used in conventional Chinese medicine. The main active components of CC are isoquinoline alkaloids, including berberine, coptisine, palmatine, and magnoflorine; all these are known to have several pharmacological properties. Poly(vinyl alcohol) (PVA) is a well-known synthetic biocompatible polymer suitable for a range of pharmaceutical uses; it can be used as a matrix for the incorporation of functional materials and has a wide range of applications in the cosmetics, food, pharmaceutical, and packaging industries. In this study, PVA-based electrospun nanofibers containing CC extract were successfully fabricated. Furthermore, the effects of different CC extract contents on the morphologies, and antimicrobial and antifungal properties of PVA/CC extract nanofibers were investigated. Morphological changes were observed using different molecular weights of PVA. For characterization, field-emission scanning electron microscopy, thermogravimetric analysis, and Fourier transform infrared analysis were performed. The effectiveness of these nanofibers has been demonstrated by evaluating the thermal stability against , antimicrobial activity against and , and the antifungal activity against the fungi and . The PVA/CC extract nanofibers were found to have excellent antibacterial and antifungal activity and thermal stability; hence, their use in medicinal sectors is highly recommended.
黄连在传统中药中被使用。黄连的主要活性成分是异喹啉生物碱,包括小檗碱、黄连碱、巴马汀和木兰碱;所有这些成分都具有多种药理特性。聚乙烯醇(PVA)是一种众所周知的合成生物相容性聚合物,适用于一系列药物用途;它可以用作掺入功能材料的基质,并且在化妆品、食品、制药和包装行业有广泛应用。在本研究中,成功制备了含有黄连提取物的基于聚乙烯醇的电纺纳米纤维。此外,研究了不同黄连提取物含量对聚乙烯醇/黄连提取物纳米纤维的形态、抗菌和抗真菌性能的影响。使用不同分子量的聚乙烯醇观察形态变化。为了进行表征,进行了场发射扫描电子显微镜、热重分析和傅里叶变换红外分析。通过评估对……的热稳定性、对……和……的抗菌活性以及对真菌……和……的抗真菌活性,证明了这些纳米纤维的有效性。发现聚乙烯醇/黄连提取物纳米纤维具有优异的抗菌和抗真菌活性以及热稳定性;因此,强烈推荐它们在医药领域的应用。
