    Phyton-International Journal of Experimental Botany, Vol.95, No.1, 2026, DOI:10.32604/phyton.2026.075566 - 30 January 2026

    Abstract Achillea species are known for their healing properties since ancient times. There is extensive literature on their pharmacological action due to their bioactive compounds. The present study aimed to investigate the antioxidant and antimicrobial effects of hydroalcoholic extracts from the inflorescences and leaves of the species Achillea crithmifolia Waldst. and Kit., A. grandifolia Friv. and A. millefolium L. The phytochemical profiles of all extracts were evaluated both by NMR spectroscopy and LC-MS analysis, and the results were consistent with the spectrophotometrically determined total phenolic (TP: 125.42–191.98 mg/g) and total flavonoid (TF: 47.34–180.02 mg/g) contents. All the extracts were tested More >

    Abstract Origanum elongatum (OE) is an aromatic, medicinal plant endemic to Morocco that is widely used in traditional medicine due to its biological properties. This study aimed to elucidate the chemical composition of the essential oil (EO) obtained from O. elongatum (OEEO) at three stages of its life cycle, including vegetative stage (OEEO-VS), flowering stage (OEEO-FS), and post-flowering (OEEO-PFS), as well as to evaluate its biological and antiradical characteristics. The chemical analysis of the essential oil was conducted using gas chromatography-mass spectrometry (GC-MS). The antibacterial activity was evaluated in vitro through distinct methodologies, namely, disc diffusion and microatmosphere assay;… More >

    Melatonin and Related Compounds as Enzymatic Antioxidants: A Comprehensive Theoretical Study

    Luis Felipe HernáNdez-Ayala1, Russel J. Reiter2, Annia Galano1,*

    BIOCELL, Vol.50, No.1, 2026, DOI:10.32604/biocell.2025.071635 - 23 January 2026

    Abstract Objectives: Oxidative stress (OS) plays a pivotal role in chronic and neurodegenerative diseases, which has sparked interest in molecules that modulate redox-regulating enzymes. Melatonin and its metabolites exhibit antioxidant properties; however, their molecular mechanisms of enzymatic and transcriptional modulation remain unclear. This study aimed to investigate, through an exploratory in silico approach, the interactions of melatonin and related compounds with OS-related enzymes to generate hypotheses about their role in cellular redox control. Methods: A rational selection of antioxidant, pro-oxidant, and transcriptional targets was performed. Ligands were optimized at the DFT level (M05-2X/6-311+G(d,p)) and docked to OS… More >

    Abstract Calophyllum inophyllum is a tropical plant that could have useful medicinal properties for pharmaceutical and cosmetic applications. The present study extracted the flower, fruit, leaf, twig, and bark of the plant by maceration in different organic solvents. The correlation between bioactive compounds and their biological activities was investigated, with emphasis on their therapeutic relevance through in silico pharmacokinetic predictions using SwissADME. Qualitative and quantitative analyses were conducted to determine the total phenolic, flavonoid, and saponin contents of the extracts. Spectral analysis of the extracts revealed –OH, C=O, C=C, and C–H functional groups. The antioxidant activity of the… More > Graphic Abstract

    Synergistic Effects of Melatonin and Methyl Jasmonate in Mitigating Drought-Induced Oxidative Stress in Common Bean (Phaseolus vulgaris)

    Totan Kumar Ghosh1, Md. Roushonuzzaman Rakib1, Munna1, S. M. Zubair AL-Meraj1, Md. Moshiul Islam2, Anika Nazran1, Mohammad Golam Mostofa3,*

    Phyton-International Journal of Experimental Botany, Vol.94, No.12, pp. 3925-3943, 2025, DOI:10.32604/phyton.2025.073382 - 29 December 2025

    Abstract The productivity of common bean (Phaseolus vulgaris L.), an economically important legume, is severely hindered by drought stress. While melatonin (Mel) and methyl jasmonate (MeJA) are known to alleviate abiotic stresses, their combined effects in mitigating drought-induced oxidative stress are unknown. Here, we examined the synergistic effects of Mel and MeJA in alleviating drought-associated oxidative damage in common bean. Compared with well-watered controls, drought stress caused a significant decline in plant biomass, photosynthetic pigments, and photosystem II efficiency (Fv/Fm). Drought also significantly increased hydrogen peroxide (H2O2) accumulation, which likely contributed to membrane lipid peroxidation, as indicated by… More >

    Abstract Selenium (Se) deficiency is a global health problem affecting more than 500 million people; crop biofortification is a sustainable strategy for its mitigation. This study investigated the effect of the application of selenate nanoparticles (SeO42−) and the combination of selenate (SeO42−) and chitosan (CS) (forming a SeO42−-CS complex) on the antioxidant profile, growth, biomass, bioactive compounds, enzymes, and Se accumulation of wheat (Triticum spp.) sprouts. Fourteen treatments were applied using a factorial design combining seven concentrations and two formulations: SeO42− and SeO42−-CS. It was identified that chitosan increased Se uptake efficiency by 30% versus conventional selenate. The optimal… More >

    Nadezhda Golubkina1,*, Pavel Poluboyarinov2, Lyubov Skrypnik3, Agnieszka Sękara4, Otilia Cristina Murariu5, Gianluca Caruso6

    Phyton-International Journal of Experimental Botany, Vol.94, No.12, pp. 3861-3877, 2025, DOI:10.32604/phyton.2025.070988 - 29 December 2025

    Abstract Circadian biorhythms are fundamental in plant adaptability and development. To reveal the effect of organic and inorganic forms of Se, foliar treatments of dandelion with 0.26 mM Se solutions were practiced in two contrasting day times: in the morning with the highest levels of leaf Se and polyphenol (TP) and the lowest dry matter, and in the evening with the opposite characteristics. Compared to the control, the morning Se supply demonstrated a higher increase of root biomass (1.27–1.37 times), Se (1.82–2.85 times), TP content (1.42–1.44 times), and antioxidant activity (AOA) (1.47–1.48 times) than the evening… More > Graphic Abstract

    Abstract Neurodegenerative diseases (NDs) such as Alzheimer’s disease (AD), Parkinson’s disease (PD), Huntington’s disease (HD), and amyotrophic lateral sclerosis (ALS) are characterized by progressive neuronal loss, which is closely linked to mitochondrial dysfunction. These pathologies involve a complex interplay of genetics, protein misfolding, and cellular stress, culminating in impaired energy metabolism, an increase in reactive oxygen species (ROS), and defective mitochondrial quality control. The accumulation of damaged mitochondria and dysregulation of pathways such as the Integrated Stress Response (ISR) are central to the pathogenesis of these conditions. This review explores the critical relationship between mitochondrial stress… More >

    Journal of Renewable Materials, Vol.13, No.12, pp. 2281-2296, 2025, DOI:10.32604/jrm.2025.02025-0067 - 23 December 2025

    Abstract The valorization of plant biomass towards high-value chemicals is a global trend aimed at solving the problem of the huge accumulation of lignocellulosic waste. Plant polysaccharides are natural polymers that make up about 20% by weight of biomass, with a unique variety of structures and properties that depend on the type of raw materials and the method of their extraction. In this study, the effect of variability of the oxidative delignification process conditions in the «acetic acid-hydrogen peroxide-water-(NH4)6Mo7O24» on the extraction and properties of aspen (Populus tremula) wood hemicelluloses was investigated for the first time.

    Abstract SnSe powdered nanoparticles (NPs) are prepared using the co-precipitation method. The powdered NPs were studied using X-ray diffraction (XRD), UV-absorbance spectroscopy, and scanning electron microscopy (SEM) characterization techniques. The XRD result indicates that NPs are orthorhombic with a crystalline size of 4 nm for TS-1, 6 nm for TS-2, and 13 nm for TS-3, respectively. The SEM images show the surface morphology of the prepared NPs is not fully spherical, but semi-flower-like. The optical properties of the powdered NPs are found by UV-Vis absorbance spectroscopy, in which the highest absorbance was found between 200 nm More >
