“…Such knowledge holds signi cant promise for the development of novel therapeutic agents with enhanced antifungal e cacy derived from natural sources. All the compound has antifungal properties but the antifungal properties of cyclopentadecanone were also reported by Gopinath et al (2020). Palmitic acid (PA) can reduce the incidence of soilborne diseases such as Fusarium wilt in watermelon and enhance the growth of economically important crop plants (Ma et al, 2021; Charlet and his co-workers, 2022).…”

Macrophomina phaseolina, a necrotrophic fungus causes multiple diseases in mungbean and other economically important crops throughout the world. The pathogen remains in soil or crop residues for up to 3 years as microsclerotia. To search for an alternative to current conventional practices against diseases that are limited and are associated with toxicity and resistance. The application of medicinal plant extracts has shown enormous antifungal potential against many sclerotial-forming phytopathogens. In the present study, a total of five concentrations (10, 20, 30, 40, and 50%) of ten different medicinal plant extracts were tested against the per cent mycelial inhibition of M. phaseolina under in-vitro conditions. The results revealed that all the plant extracts showed significant mycelial inhibition at all concentrations over the check. The maximum per cent mycelial inhibition was recorded in giloy (70.5%) followed by curry leaf (60.7%) which was at par with eucalyptus (56.0%) followed by lemon grass (50.8%) and bhang (46.5%) at 50% concentration. Maximum, total phenol (291 mg GAE/g) and flavonoid (179 mg QE/g) content exhibited in giloy. The qualitative analysis of plant extracts indicates the presence of flavonoids, alkaloids, phenols and proteins. GC-MS analysis of the giloy (Tinospora cordifolia) showed the presence of 32 phytochemical compounds, whereas cyclopentadecanone was the predominant compound with 28.45% peak area followed by 2- bromododecane (25.93%), palmitic acid, TMS derivative (10.78%), 2-hexadeccen-1-ol,3,7,11,15-tetramethyl (5.04%), 2-hexadecen-1-ol, 3,7,11,15-tetramethyl (5.04%), tetracosane (4.88%), hexanoic acid, 4-hexadecyl ester (4.12) and butylated hydroxytoluene (0.79%). Some of these major compounds might be responsible for the antifungal properties of Tinospora cordifolia against M. phaseolina.

A rapid green synthesis of silver nanoparticles (AgNPs) using plant extract Solenostemo monastachyus (S. monastachyus) with silver nitrate is reported here. The formation of AgNPs was confirmed by a colour change in the plant extract from pale yellow to reddish brown and was further characterized by UV-Vis spectrophotometric, FT-IR, SEM, EDX and XRD analyses. Ag+ ions were reduced by the phytochemicals present in the extract. A characteristic single broad peak was observed at 450 nm and has been ascribed to the excitation of surface plasmon resonance phenomenon. The efficient capping and stabilization properties of the NPs were revealed by the FT-IR analysis. SEM and XRD results showed the formation of spherical shaped AgNPs with the average particle size of less than 100 nm and EDX confirmed the presence of silver in the prepared AgNPs. The antimicrobial properties of the biosynthesized AgNPs was evaluated against some selected bacterial and fungal species. The prepared AgNPs had notable antimicrobial activity against the selected bacterial and fungal species. Thus, the biosynthesized AgNPs could be a good lead for antimicrobial agent.

“…Nanotechnology involves the design, synthesis, and manipulation of nanoparticles (1–100 nm), although this concept has changed over time ( Azarbani and Shiravand, 2020 ). Interest in nanotechnology has recently sharply increased due to its unique properties in applications in various fields including electronics, the optical industry, and medicine ( Das et al, 2013 ; Gopinath et al, 2020 ). Their size gives nanoparticles unique physical and chemical properties over their larger counterparts ( Verma and Maheshwari, 2019 ; Raj et al, 2021 ).…”

This study describes the biosynthesis of silver nanoparticles (AgNPs) using Balanites aegyptiaca (B. aegyptiaca) leaf extract. The biosynthesized AgNPs were characterized by UV-Vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), dynamic light scattering (DLS), X-ray diffraction (XRD), Raman spectroscopy, transmission electron microscopy (TEM) and scanning electron microscopy with (SEM-EDS). The AgNPs showed an average size of 10–20 nm, spherical shape, and crystalline nature. The application of these synthesized AgNPs to dye degradation showed that the AgNPs removed the two organic pollutants methylene blue (MB, 93.47%) and congo red (CR, (78.57%). In vitro investigation of the antifungal activity of the AgNPs against Fusarium oxysporum, a phytopathogenic fungus, showed a maximum percent radial growth inhibition of 82.00 ± 1.00% and a spore percent inhibition of 73.66 ± 3.94 for 150 μg/ml of biosynthesized AgNPs.
