The phytochemical composition and biological activities of Spartium junceum flower extracts were studied after fractionation using solvents of increasing polarity. Among the tested fractions, the butanol extract exhibited the highest levels of total phenolics, flavonoids, flavonols, and tannins, suggesting enrichment in polar bioactive metabolites. Gas chromatography-mass spectrometry (GC–MS) analysis revealed that the major constituents were mainly fatty acids and unsaturated lipid derivatives, including n-hexadecanoic acid, linoelaidic acid, oleic acid, and linoleic acid methyl ester. The butanol fraction demonstrated significant cytotoxic activity against MCF-7 breast and PC-3 prostate cancer cell lines, with IC₅₀ values of 96 and 89.8 µg/mL, respectively, while showing lower toxicity toward normal WI-38 cells. Moderate antioxidant activity was confirmed using (2,2-diphenyl-1-picryl-hydrazyl-hydrate), (2,2 (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and total antioxidant capacity assays, with the strongest scavenging effect observed in the ABTS method. Additionally, the extract showed pancreatic lipase inhibitory potential (IC₅₀ = 79.6 µg/mL) and concentration-dependent antibiofilm activity against Staphylococcus aureus and Escherichia coli. These findings support S. junceum flowers as a promising source of multifunctional natural therapeutics. - Impact of organic bio-stimulant on bacterial blight of beans: mechanism of pathogenesis-related proteins and defense system

International Journal of Molecular Sciences, 2026
Due to the indiscriminate use of antimicrobial drugs in the treatment of infectious diseases, human pathogenic bacteria have developed resistance to many commercially available antibiotics. Medicinal plants such as Convolvulus arvensis represent a renewable resource for the development of alternative therapeutic agents. This study aimed to evaluate the antibacterial activity of silver nanoparticles (AgNPs) biosynthesized from C. arvensis against two clinical antibiotic-resistant bacterial isolates. The pathogenic isolates were identified as Staphylococcus aureus MRSA and Escherichia coli ESBL using 16S rRNA gene sequencing. Silver nanoparticles were synthesized via a green synthesis approach, and their physicochemical properties were characterized using UV–Vis spectroscopy, scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, zeta potential, and dynamic light scattering (DLS). The synthesized C. arvensis–AgNPs exhibited a surface plasmon resonance peak at 475 nm and predominantly spherical morphology with particle sizes ranging from 102.34 to 210.82 nm. FTIR analysis indicated the presence of O–H, C–O, C–N, C–H, and amide functional groups. The nanoparticles showed a zeta potential of −18.9 mV and an average hydrodynamic diameter of 63 nm. The antibacterial activity of the biosynthesized AgNPs was evaluated against methicillin-resistant S. aureus (MRSA and ATCC 29213) and E. coli (ESBL and ATCC 25922) using agar diffusion, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) assays. Inhibition zones ranged from 10 to 13 mm, with MIC and MBC values of 12.5–25 µg/mL and 25–50 µg/mL, respectively. In addition, the nanoparticles exhibited antioxidant activity (DPPH assay, IC50 = 0.71 mg/mL) and anti-inflammatory effects as determined by protein denaturation inhibition. No cytotoxic effects were observed in the MCF-7 cell line at the MIC level. These findings suggest that C. arvensis–AgNPs have potential as natural antimicrobial, antioxidant, and anti-inflammatory agents. - He–Ne laser irradiation enhances curcuminoid content in Curcuma longa: a green strategy for functional antioxidants and antimicrobial ingredients

Introduction Curcuma longa rhizomes are rich in curcuminoids with strong antioxidant and antimicrobial activities. Sustainable post-harvest strategies are needed to enhance these bioactive metabolites for functional food applications. Methods Fresh rhizomes were irradiated with a He–Ne laser for 5, 10, or 15 min. Ethanol extracts were analyzed by High Performance Liquid Chromatography analysis (HPLC) to quantify curcuminoids. Antioxidant activity was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays, and antibacterial activity tested against Escherichia coli ( E. coli ), Staphylococcus aureus ( S. aureus ), and Streptococcus pyogenes ( S. pyogenes ). Results Laser treatment increased curcuminoid content in a time-dependent manner, with 15-min exposure yielding the highest bisdemethoxycurcumin enrichment. Antioxidant assays showed strong scavenging potential, with IC50 values of 0.71 (10-min) and 0.69 mg mL −1 (15-min). Extracts exhibited enhanced antibacterial activity, with 15-min exposure strongest against E. coli and S. aureus , while 10-min treatment yielded higher inhibition of S. pyogenes . Discussion He–Ne laser irradiation is an effective green technique to improve the antioxidant and antimicrobial properties of C. longa extracts, supporting their use as natural functional ingredients. - Ethanolic extract of Commiphora myrrha gum-resin promotes therapeutic compound accumulation in Achillea fragrantissima under in vitro culture

Frontiers in Plant Science, 2026
Introduction Achillea fragrantissima is valued for its broad spectrum of secondary metabo-lites with notable therapeutic potential. This study examined the influence of an ethanolic extract of Commiphora myrrha gum-resin on in vitro shoot growth, callus formation, and the effect of compound composition in A. fragrantissima. Material and methods Shoot-tip and root-segment explants were cultured on Murashi-ge and Skoog (MS) medium supplemented with filter-sterilized C. myrrha ethanolic extract at 0.5, 1.0, and 2.0 g·L -1 , alongside control treatment. Plant responses, including growth parameters, callus induction percentage and biomass, photosynthetic pigments, and me-tabolite composition, were assessed after one month of in vitro culture. GC–MS analysis was performed on the C. myrrha extract and on methanolic extracts of A. fragrantissima plantlets and callus tissues obtained from different treatments. Results GC–MS analysis of the ethanolic extract of C. myrrha identified 66 phytochemi-cal compounds dominated by sesquiterpenes—particularly 2,5,8-trimethyl-1-nonen-3-yn-5-ol, curzerene, myrcenol, germa-cra-1(10),4,11(13)-trien-12-oic acid, and several oxygenated sesquiterpenes—indicating a rich pool of bioactive, growth-promoting constituents. Shoot-tip and root-segment ex-plants showed the strongest responses to C. myrrha extract at specific concentrations. The highest concentration tested (2.0 g·L -1 ) produced the most shoots and the greatest accu-mulation of photosynthetic pigments, including total chlorophyll and carotenoids. In contrast, the lowest concentration (0.5 g·L -1 ) promoted the longest shoots, the highest fresh weight, and the greatest number of leaves. Callus formation from shoot tips was also highest at 0.5 g•L -1 , while root-derived callus reached full induction at both 0.5 and 2.0 g·L -1 . Both shoot-tip plantlets and root-derived callus showed notable modifications in their bioactive constituents. Several bioactive constituents were notably elevated (e.g., de-sulphosinigrin, thymidine, 4H-pyran-4-one derivatives, and fatty acid derivatives). Discussion Distinct tissue-specific patterns emerged, shoot tips accumulated a wider range of aromatic and therapeutic compounds, whereas callus tissue was enriched in fat-ty acids. These findings suggest that C. myrrha extract functions as a natural biostimulant and elicitor, providing a sustainable approach for producing metabolite-rich A. fragrantis-sima material with potential pharmacological applications. - Ag-decorated ZnO/MgO nanocomposite derived from Cinnamomum camphora: synthesis and functional evaluation
