“…The most important reducing and capping agents in plant extracts are proteins, polysaccharides, flavonoids, and terpenoids [23]. According to our previous report T. diffusa extracts include at least 47 chemical compounds comprising flavonoids, terpenoids, saccharides, phenolics, and cyanogenic derivatives [29].…”

“…Probably, Gram-negative bacteria could be more susceptible to metallic NPs because their positive charges interacted with the negatively charged LPS, resulting in membrane holes and cell death [37]. Additionally, antibacterial activity of Damiana extracts has been demonstrated, and AuNPs adsorbed bioactive compounds could contribute to this effect [29].…”

“…The results in this study suggest that AuNPs@Damiana might be a promising system with potential use in nanomedicine and biotechnological applications. The microplate assay method was used for determining AuNPs@Damiana antibacterial activity [29]. Each microplate well was filled with 100 μL of LB and 20 μL of AuNPs@Damiana at concentrations of 0, 200, 400, 600 and 800 μg/mL.…”

“…T. difussa extracts contain more than 47 organic compounds comprised of flavonoids, terpenoids, saccharides, phenolics, and cyanogenic derivatives [28]. Recently, our group has reported that T. difussa extracts show antimicrobial activity against Gram-negative bacterium [29]. This property -together with the possibility that T. difussa extracts can reduce and stabilize AuNPs-makes the AuNPs@Damiana systems a novel compound with potential uses in biotechnology and biomedicine.…”

Interest in green synthesis methods for nanoparticle production with potential use in biology, pharmacy, and medicine is a forefront field in research. Among the routes described in the literature, the use of plant extracts as reducing and capping agents is one of the most promising. Turnera diffusa commonly called Damiana is a wild shrub traditionally used as aphrodisiac, diuretic, and for cancer and diabetes treatments. Its extracts are rich in flavonoid, phenolic, terpenoid, and other active compounds that possess antiallergic, antiviral, and antifungal activities. Besides, flavonoids have been reported to have a redox potential sufficient for metal ion reduction. Thus, this study reports a novel and facile method for green gold nanoparticle (AuNPs) synthesis using T. diffusa extracts. The samples were fully characterized by scanning electron microscopy, acrylonitrile butadiene styrene ultraviolet-visible, dynamic light scattering, X-ray photoelectron, and inductively coupled plasma optical emission spectroscopies. The results showed high efficiency of T. diffusa extracts to reduce and stabilize the AuNPs which showed spherical shape, 24 nm diameter, negative surface charge, and high colloidal stability at biological pH and alkaline media. Additionally, its antimicrobial activity was evaluated showing high antiseptic capacity against gram-negative Salmonella enteritis and Escherichia coli ATCC 8739 bacteria.

“…Recently, this research group analysed for the first time the biological and immunological properties of a native plant of the Baja Californian desert in Mexico—Damiana de California ( Turnera diffusa Willd) in fish. Interestingly, a notable antimicrobial activity and great potential therapeutic properties were found by enhancing the antioxidant capacity and immune parameters in Longfin yellowtail Seriola rivoliana (Reyes‐Becerril et al, 2020). Damiana de California, T. diffusa is rich in essential oils, flavonoids and polyphenols (Alcaraz‐Meléndez et al, 2004; Reyes‐Becerril et al, 2020).…”

Plant‐mediated nanoparticle synthesis is an eco‐friendly method designed to reduce toxicity. This research reports the effects of gold nanoparticle green synthesis on immune modulation for the first time, using aqueous extract from Turnera diffusa. First, the chemical composition showed that T. diffussa is abundant in compounds, such as oplopanone, γ‐eudesmol, hydroquinone‐β‐d‐glucoside (arbutin) and inositol. The synthesized gold nanoparticles (AuNPDam) were confirmed by ultraviolet visible (UV‐Vis) spectrophotometry; the micro‐graphical analysis confirmed the average size that was estimated about 24 nm, which were mostly spherical in shape. The Fourier transform infrared spectroscopy (FTIR) technique helped to confirm the functional groups of the synthesized AuNPDam. Its antioxidant capability was analysed using 2,2‐diphenyl‐1‐picrylhydarzyl (DPPH), superoxide radical scavenging and fluorescence recovery after photobleaching (FRAP) methods. These results indicated a worthy antioxidant activity. The synthesized AuNPDam showed strong antibacterial activity against Vibrio parahaemolyticus and Aeromonas hydrophila. Interestingly, AuNPDam were nontoxic to Longfin yellowtail head kidney leukocytes after 24 h. The phagocytosis activity, production of reactive oxygen species and nitric oxide were also enhanced in leukocytes treated with AuNPDam. Overall, the results suggested that AuNPDam is non‐cytotoxic, displays strong bactericidal activity and has therapeutic properties by enhancing the immune system.
