INTRODUCTION
Zingiber officinale extract has emerged as a compelling candidate for green synthesis of nanoparticles, offering diverse applications across medicine, cosmetics, and nutrition. This study delves into the investigation of in vitro toxicity and explores the biomedical utility of green-synthesized silver nanoparticles derived from ginger extract (GE-AgNPs).
METHODS
We employed established protocols to evaluate in vitro aspects such as antioxidant capacity, anti-inflammatory potential, and biocompatibility of GE-AgNPs. Additionally, molecular docking was employed to assess their anti-lipoxygenase (anti-LOX) activity.
RESULTS
Our findings highlight that the extraction of ginger extract at a pH of 6, utilizing a cosolvent blend of ethanol and ethyl acetate in a 1:1 ratio, yields heightened antioxidant capacity attributed to its rich phenolic and flavonoid content. In the context of silver nanoparticle synthesis, pH 6 extraction yields the highest quantity of nanoparticles, characterized by an average size of 32.64 ± 1.65 nm. Of particular significance, GE-AgNPs (at pH 6) demonstrated remarkable efficacy in scavenging free radicals, as evidenced by an IC value of 6.83 ± 0.47 µg/mL. The results from the anti-LOX experiment indicate that GE-AgNPs, at a concentration of 10 µg/mL, can inhibit LOX activity by 25%, outperforming ginger extract which inhibits LOX by 17-18%. Notably, clionasterol exhibited higher binding energy and enhanced stability (-8.9 kcal/mol) compared to nordihydroguaiaretic acid. Furthermore, a cell viability study confirmed the safety of GE-AgNPs at a concentration of 17.52 ± 7.00 µg/mL against the L929 cell line.
CONCLUSION
These comprehensive findings underscore the significant biomedical advantages of GE-AgNPs and emphasize their potential incorporation into cosmetic products at a maximum concentration of 10 µg/mL.
简介
姜黄提取物已成为绿色合成纳米粒子的有力候选物,在医学、化妆品和营养领域具有广泛的应用。本研究深入探讨了体外毒性,并探索了源自姜黄提取物(GE-AgNPs)的绿色合成银纳米粒子的生物医学用途。
方法
我们采用既定的方案来评估 GE-AgNPs 的体外抗氧化能力、抗炎潜力和生物相容性。此外,还采用分子对接来评估其抗脂氧合酶(anti-LOX)活性。
结果
我们的研究结果表明,在 pH 值为 6 时提取姜黄提取物,使用乙醇和乙酸乙酯的混合溶剂(比例为 1:1),可获得更高的抗氧化能力,这归因于其丰富的酚类和类黄酮含量。在银纳米粒子合成方面,pH 值为 6 的提取物可产生最高量的纳米粒子,其平均粒径为 32.64±1.65nm。值得注意的是,在 pH 值为 6 时,GE-AgNPs 对自由基的清除能力表现出显著的功效,其 IC 值为 6.83±0.47µg/mL。抗 LOX 实验的结果表明,浓度为 10µg/mL 的 GE-AgNPs 可抑制 LOX 活性达 25%,优于抑制 LOX 活性达 17-18%的姜黄提取物。值得注意的是,clionasterol 的结合能更高,稳定性更强(-8.9kcal/mol),优于 nordihydroguaiaretic acid。此外,细胞活力研究证实,GE-AgNPs 在 17.52±7.00µg/mL 的浓度下对 L929 细胞系是安全的。
结论
这些综合研究结果突出了 GE-AgNPs 在生物医学方面的显著优势,并强调了其在化妆品产品中的潜在应用,最大浓度为 10µg/mL。
