The Multidrug Drug Resistance (MDR) and Pan-Drug Resistance (PDR) remain an intractable challenge issue in public health, worldwide. Plant extracts-based biological macromolecules containing a diverse array of secondary metabolites could be potentially used as alternative approaches to control or limit MDR/PDR infections. Plants of the Solanaceae family exhibit a wide variety of secondary metabolites with antioxidant and antimicrobial properties, which render them a significant role in food and pharmaceutical applications. To our knowledge, this is the first report on phytochemical constituents, antioxidant, antimicrobial activities and toxicological safety of leaf extracts. Results revealed that phenolics and flavonoids were found to be the most abundant compounds in all extracts. Antioxidant activity of extracts was measured using DPPH and ABTS assays and the methanol extract displayed superior scavenging activity (IC = 0.06 and 0.007 mg/mL for DPPH and ABTS, respectively). Results of the GC-MS analysis revealed the identity of 10 compounds. Moreover, toxicological assessment can confirm the safety of for use. Overall, leaves are a promising natural source for the development of novel antimicrobial and antioxidant agents that could potentially combat clinical MDR/PDR pathogens.
多重耐药(MDR)和泛耐药(PDR)仍然是全球公共卫生领域一个棘手的挑战性问题。含有多种次生代谢物的基于植物提取物的生物大分子可能被用作控制或限制MDR/PDR感染的替代方法。茄科植物表现出具有抗氧化和抗菌特性的多种次生代谢物,这使其在食品和制药应用中发挥重要作用。据我们所知,这是关于叶提取物的植物化学成分、抗氧化、抗菌活性和毒理学安全性的第一份报告。结果显示,酚类和黄酮类化合物是所有提取物中含量最丰富的化合物。使用DPPH和ABTS法测定提取物的抗氧化活性,甲醇提取物表现出优异的清除活性(DPPH和ABTS的IC分别为0.06和0.007mg/mL)。气相色谱-质谱联用(GC-MS)分析结果揭示了10种化合物的身份。此外,毒理学评估可以确认其使用安全性。总体而言,叶是开发新型抗菌和抗氧化剂的有前景的天然来源,这些药剂可能对抗临床MDR/PDR病原体。
