植物提取物合成银纳米颗粒（Ag NPs）等方法由于其环保的特点成为一种有前途的方法。本研究旨在研究藤黄果果实化学成分在Ag NPs的生物合成中的应用，评估其抗菌、抗氧化和抗癌性质，以及生物合成Ag NPs对结晶紫（CV）三苯甲烷染料的光催化能力。通过紫外可见光谱（UV-Vis）、X射线衍射（XRD）、傅里叶变换红外光谱（FTIR）、扫描电子显微镜（SEM）、Zeta电位分析和透射电子显微镜（TEM）对通过绿色途径合成的Ag NPs的物理特性进行了表征。使用合成的Ag NPs在紫外光下，通过分析579 nm处的吸收峰来确定CV的染料降解效率。使用稀释法研究了Ag NPs对大肠杆菌、金黄色葡萄球菌、热带白念珠菌和白念珠菌的抗菌效果。使用DPPH和MTT试验评估了合成的Ag NPs的抗氧化和抗癌性质。紫外分析显示，合成的Ag NPs峰位于442 nm。FTIR、XRD、Zeta电位、SEM和TEM分析的数据证实了纳米颗粒的形成。SEM和TEM分析确定了球形纳米颗粒的存在，平均尺寸分别为29.12 nm和24.18 nm。在320分钟后，CV的染料降解效率最高达到90.08％，并且没有银离子渗出，证实了Ag NPs的光催化活性。采用Allium cepa根生长抑制试验、Vigna radiata的毒性分析以及盐水虾致死试验评估了处理的生物效能。结果表明，相对于物理/化学合成的Ag NPs来说，绿色Ag NPs具有环境友好的特点。合成的Ag NPs可以有效用于生物医学和光催化应用。 © 2023 作者发表。IMR Press出版。

Methods like the bio-synthesis of silver nanoparticles (Ag NPs) using plant extracts have become promising due to their eco-friendly approach. The study aimed to examine the utilization of Garcinia gummi-gutta fruit phytochemicals as agents in the biosynthesis of Ag NPs, evaluation of the antimicrobial, antioxidant, and anti-cancerous properties, as well as the photocatalytic ability of bio-synthesized Ag NPs against Crystal Violet (CV), a triphenylmethane dye.The characterization of the physical properties of the Ag NPs synthesized via the green route was done using UV-Vis spectrophotometry (UV-Vis), X-ray Diffraction (XRD), Fourier Transform Infrared Spectrophotometry (FTIR), Scanning Electron Microscopy (SEM), Zeta potential analysis, and Transmission Electron Microscopy (TEM). The dye degradation efficiency of CV was determined using synthesized Ag NPs under UV light by analyzing the absorption maximum at 579 nm. The antimicrobial efficacy of Ag NPs against E. coli, S. aureus, Candida tropicalis, and Candida albicans was examined using the broth dilution method. The antioxidant and anti-cancer properties of the synthesized Ag NPs were assessed using the DPPH and MTT assays.The UV analysis revealed that the peak of synthesized Ag NPs was 442 nm. Data from FTIR, XRD, Zeta potential, SEM, and TEM analysis confirmed the formation of nanoparticles. The SEM and TEM analysis identified the presence of spherical nanoparticles with an average size of 29.12 nm and 24.18 nm, respectively. Maximum dye degradation efficiency of CV was observed at 90.08% after 320 min without any silver leaching, confirming the photocatalytic activity of Ag NPs. The bio-efficiency of the treatment was assessed using the Allium cepa root growth inhibition test, toxicity analysis on Vigna radiata, and Brine shrimp lethality assay.The findings revealed the environmentally friendly nature of green Ag NPs over physical/chemically synthesized Ag NPs. The synthesized Ag NPs can effectively be used in biomedical and photocatalytic applications.© 2023 The Author(s). Published by IMR Press.
