“…Ar-AgNPs were more active than silver ions against the tested bacterial species, no activity was observed against C. albicans. By contrast, AgNPs prepared using A. absinthium have been shown to have significant activity against pathogenic yeasts of the Candida genus (del Pilar Rodríguez-Torres et al, 2019). This discrepancy might indicate that the smaller AgNPs prepared using A. absinthium in the earlier study (relative to the AgNPs prepared in our study) might confer increased activity against Candida spp.…”

“…Current developments in the field of nanomedicine have led to great opportunities for nanostructure formation using biogenic agents, providing a simple approach for producing particles with unique characteristics than can combat multidrug-resistant (MDR) bacteria. To the best of our knowledge, that this study is the first to report and analyze AgNP biosynthesis using A. hierochuntica, although (del Pilar Rodríguez-Torres et al, 2019) previously tested AgNP production using A. absinthium. AgNP biosynthesis proceeded first via a slow color change, after 24 h, the color intensity stabilized, and no further changes were observed, suggesting that color intensity was a time-dependent variable at room temperature.…”

The latest advances in green nanoparticle synthesis have preserved natural and non-renewable resources and decreased environmental pollution. The current study was designed to evaluate silver nanoparticles (AgNPs) fabricated using aqueous extracts of two medicinal plants, Anastatica hierochuntica L. (Kaff Maryam) and Artemisia absinthium. The phytochemicals were detected by Fourier-transform infrared spectroscopy (FTIR) and Chromatography/Mass Spectrometry (GC-MS). The effects of the AgNPs on Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, and Candida albicans as well as the cytotoxicity against MDA-MB-231 cells were examined. The synergistic and antagonistic effects of the biogenic AgNPs in combination with standard antibiotics against several microbes were also investigated. The ability of the plant extracts to transfer silver ions to AgNPs was measured via dynamic light scattering, zeta potential measurement, and transmission electron microscopy. The most sensitive microbes to AgNP treatment were examined via scanning electron microscopy to assess morphological changes. Biogenic AgNPs showed significant antibacterial effects against most of the tested microbes and significant cytotoxicity was noted. Polysaccharides, proteins and Phenolic compounds are likely involved in AgNP biosynthesis since hydroxyl groups and amides were detected via FTIR as well as GC-MS. This study confirmed that plant-based AgNP fabrication with AgNO3 as the Ag (I) delivering salt can be an economical and practical approach for large-scale production of particles with antimicrobial and cytotoxic potential. The synergistic effects of biogenic AgNPs in combination with some antibiotics support their potential as a safe therapeutic for bacterial infections because they are capped with organic biomolecules.

“… 23 Rodríguez-Torres et al reported the cooperative antifungal assay of spherical Ag NPs with Artemisia absinthium toward few Candida sp. 24 It has been found that they bind to a wide range of targets in proteins which made them as potential non-resistant antimicrobial agents. 25 However, the effectiveness of Ag NPs as antimicrobial agents have been found dependent on shape, size, and uniformity of nanoparticles, as it does in a plethora of other applications such as catalysis, optics, and electronic applications.…”

Deciphering the Kinetic Study of Sodium Dodecyl Sulfate on Ag Nanoparticle Synthesis Using Cassia siamea Flower Extract as a Reducing Agent

Silver nanoparticles (Ag NPs) were synthesized using Cassia siamea flower petal extract (CSFE) as a reducing agent for the first time. In its presence and absence, the correlative effects of the anionic surface-active agent sodium dodecyl sulfate (SDS) were studied with respect to the development and texture of Ag NPs. Under different reagent compositions, the Ag NPs were inferred by localized surface plasmon resonance peaks between 419 and 455 nm. In the absence of SDS, there was a small eminence at 290 and around 350 nm, pointing toward the possibility of irregular polytope Ag NPs, which was confirmed in the transmission electron microscopy images. This elevation vanished beyond the cmc of [SDS], resulting in spherical and oval shaped Ag NPs. The effects of reagent concentrations were studied at 25 °C and around 7 and 9 pH in the absence and presence of SDS, respectively. Also, kinetic studies were performed by UV–visible spectrophotometry. Prodigious effects on shape and size were found under different synthesis conditions in terms of hexagonal, rod-, irregular-, and spherical shaped Ag NPs. Furthermore, the antimycotic activity of the synthesized Ag NPs was established on different Candida strains, and best results were found pertaining Candida tropicalis . The ensuing study impels the control of texture and dispersity for Ag NPs by CSFE and SDS, and the resultant polytope Ag NPs could be a future solution for drug-resistant pathogenic fungi.

“…La planta de ajenjo se ha empleado como remedio tradicional para tratar los casos de malas digestiones, pesadez de estómago y desarreglos intestinales, además de para estimular el apetito, limpiar el hígado y la vesícula biliar, favorecer la menstruación, y tratar el dolor de estómago, entre otros trastornos (Obón et al 2014). Recientemente, se han llevado a cabo estudios de bioactividad que ponen de manifiesto el potencial de esta especie y sus extractos como nematicidas (Liu et al 2019;Pino-Otín et al 2019), insecticidas (Guevara et al 2019), antifúngicos (Liu et al 2019;Rodríguez-Torres et al 2019) y anticancerígenos (Mughees et al 2019;Wei et al 2019).…”

Con el fin de profundizar en el conocimiento relativo a las plantas medicinales y a los remedios tradicionales que de ellas se derivan, se ha analizado la composición química de la planta de ajenjo (Artemisia absinthium L.) y de su infusión. Tanto en la planta como en la infusión se ha determinado la presencia de fenoles, taninos, flavonoides y terpenoides mediante ensayos cualitativos. Los análisis llevados a cabo mediante cromatografía de gases acoplada a espectrometría de masas (GC-MS) han permitido identificar (Z)-β-epoxiocimeno (8,2%), isobutirato de nerilo (7,53%), β-tuyona (7,20%), isobutirato de geranilo (6,85%), butirato de geranilo (6,53%) y acetato de trans-crisantemilo (5,19%) como los componentes mayoritarios del aceite esencial de la planta, y, por otro lado, α-bisabolol (11,87%), (Z)-β-epoxiocimeno (10,82%), camazuleno (9,72%), geraniol (8,67%), nerol (8,29%) y espatulenol (7,46%) como mayoritarios en la infusión. La presencia de estos volátiles en la infusión de ajenjo se ha confirmado por primera vez en este trabajo.
