Cannabis is considered (Cannabis sativa L.) a sacred herb in many countries and is vastly employed in traditional medicine to remedy numerous diseases, such as diabetes. This research investigates the chemical composition of the aqueous extracts from Cannabis sativa L. seeds. Furthermore, the impact of these extracts on pancreatic α-amylase and lipase, and intestinal α-glucosidase enzymes is evaluated, as well as their antihyperglycemic effect. Analysis of the chemical composition of the aqueous extract was conducted using high-performance liquid chromatography with a photodiode array detector (HPLC-DAD). In contrast, the ethanol, hexanic, dichloromethane, and aqueous extract compositions have been established. Additionally, the inhibitory effects of ethanolic, dichloromethane, and aqueous extracts on pancreatic α-amylase and lipase, and intestinal α-glucosidase activities were evaluated in vitro and in vivo. The results of HPLC analysis indicate that the most abundant phenolic compound in the aqueous cannabis seed extract is 3-hydroxycinnamic acid, followed by 4-hydroxybenzoic acid and rutin acid. Moreover, administration of ethanolic and aqueous extracts at a dose of 150 mg/Kg significantly suppressed postprandial hyperglycemia compared to the control group; the ethanolic, dichloromethane, and aqueous extracts significantly inhibit pancreatic α-amylase and lipase, and intestinal α-glucosidase in vitro. The pancreatic α-amylase test exhibited an inhibition with IC₅₀ values of 16.36 ± 1.24 µg/mL, 19.33 ± 1.40 µg/mL, 23.53 ± 1.70 µg/mL, and 17.06 ± 9.91 µg/mL for EAq, EDm, EET, and EHx, respectively. EET has the highest inhibitory capacity for intestinal α-glucosidase activity, with an IC₅₀ of 32.23 ± 3.26 µg/mL. The extracts inhibit porcine pancreatic lipase activity, demonstrating their potential as lipase inhibitors. Specifically, at a concentration of 1 mg/mL, the highest inhibition rate (77%) was observed for EDm. To confirm these results, the inhibitory effect of these extracts on enzymes was tested in vivo. The oral intake of aqueous extract markedly reduced starch- and sucrose-induced hyperglycemia in healthy rats. Administration of the ethanolic extract at a specific dose of 150 mg/kg significantly reduced postprandial glycemia compared with the control group. It is, therefore, undeniable that cannabis extracts represent a promising option as a potentially effective treatment for type 2 diabetes.

The corrosion of metals in acidic environments remains a significant challenge, driving the search for sustainable and eco‐friendly inhibitors derived from natural sources. This study evaluates the corrosion inhibition potential of three extracts from Cannabis sativa L., namely ethanol extract (EET), hexane extract (EHX), and dichloromethane extract (EDM), for mild steel in a 1 M HCl acidic medium. The investigation employed weight loss (WL) measurements, electrochemical impedance spectroscopy (EIS), and potentiodynamic polarization (PDP) techniques. To understand their inhibitive performance, density functional theory (DFT) was used. For a more comprehensive theoretical analysis, Monte Carlo (MC) and molecular dynamics (MD) simulations were used. The corrosion inhibition efficiency increased with the increase of EET, EHX, and EDM concentrations up to 91 %, 89 %, and 83 %, respectively, obtained at 308 K for a 0.8 g/L concentration. Polarization studies classify EET, EHX, and EDM as mixed‐type inhibitors with a predominantly anodic effect, functioning through adsorption on the metal surface. The adsorption of these extracts on mild steel conforms to the Langmuir isotherm model, with adsorption equilibrium constants (K _ads ) of 3.0143 M, 5.1245 M, and 2.2009 M for EET, EHX, and EDM, respectively, highlighting their potential as effective corrosion inhibitors. The EET extract exhibits a high activation energy (E _a ) of 101.70 kJ/mol, while the EHX and EDM extracts show E _a values of 79.05 kJ/mol and 82.93 kJ/mol, respectively, all significantly higher than the E _a of blank, which is 30.23 kJ/mol, indicating that the extracts effectively inhibit corrosion by increasing the activation energy, with EET being the most potent inhibitor. Theoretical approaches based on DFT, MC, and MD simulations clearly explain the mode of adsorption of the majority of molecules on the metal surface. The inhibition process may result from a synergistic intermolecular effect of the major compounds in the extract, which interact at various active adsorption sites on the metal surface. Simulations indicate that catechin dihydrate in EET (52.42 %), linoleic acid in EHX (42.92 %), and naringenin in EDM (41.92 %) are close to the metal surface, suggesting strong interactions with the material. The results obtained from experimental measurements and theoretical calculations agree, highlighting the potential for developing more sustainable corrosion inhibitors based on plant‐derived compounds.

The present study introduces an innovative approach to sustainable corrosion inhibition by utilizing the aerial parts of Ephedra fragilis (EF) as a natural inhibitor for steel in hydrochloric acid solutions. Unlike conventional synthetic inhibitors, EF extracts offer an eco-friendly and renewable alternative, emphasizing their potential for industrial applications. Both water and ethanolic extracts were evaluated, and their bioactive compounds were identified using high-performance liquid chromatography. The ethanolic extract was rich in p-coumaric acid , sinapic acid , and hydrated catechin , while the aqueous extract predominantly contained catechin , gallic acid , and 3-hydroxybenzoic acid . Electrochemical techniques, including open circuit potential, electrochemical impedance spectroscopy, and potentiodynamic polarization, demonstrated remarkable corrosion inhibition efficiency, reaching up to 97%. The extracts exhibited mixed-type inhibition behavior, with efficiency improving as the concentration increased. Specifically, inhibition efficiencies of 96.13 and 96.84% were achieved using the Tafel method, highlighting the superior performance of EF extracts compared to many synthetic counterparts. Furthermore, scanning electron microscopy revealed the formation of a dense, protective organic layer on the steel surface, which underpins the high inhibition efficiency. This study not only validates the use of EF as an efficient, sustainable corrosion inhibitor but also opens new avenues for the integration of plant-based inhibitors into industrial practices, providing a long-term, eco-friendly solution to steel corrosion challenges.

Wild seeds constitute a taxonomically diverse and underexplored reservoir of C18-series bioactive fatty acids (BFAs) with significant nutritional, biomedical, and industrial relevance. This review integrates current knowledge on their lipid composition, metabolic architecture, and potential applications. Numerous wild taxa accumulate high levels of oleic, linoleic, α-linolenic, γ-linolenic, and stearidonic acids, while others synthesise structurally specialised compounds such as punicic, petroselinic, and sciadonic acids. These FAs, together with tocopherols, phytosterols, and phenolics, underpin antioxidant, anti-inflammatory, immunomodulatory, and cardiometabolic effects supported by in vitro and in vivo evidence. The occurrence of these unusual lipids reflects lineage-specific modulation of plastidial and endoplasmic-reticulum pathways, including differential activities of SAD, FAD2/3, Δ6- and Δ5-desaturases, elongases, and acyl-editing enzymes that determine the final acyl-CoA and TAG pools. Wild seed oils show strong potential for translation into functional foods, targeted nutraceuticals, pharmacologically relevant lipid formulations, cosmetic ingredients, and bio-based materials. However, their exploitation is constrained by ecological sustainability, oxidative instability of PUFA-rich matrices, antinutritional constituents, and regulatory requirements for novel lipid sources. This review positions wild seeds as high-value, underused lipid resources with direct relevance to health and sustainability. It underscores their potential to enhance nutritional security and offer alternatives to conventional oil crops.

Oral diseases remain widespread, while concerns about antimicrobial resistance, microbiome disruption, and adverse effects from prolonged antiseptic use encourage interest in plant-based approaches. This structured narrative review synthesises literature published predominantly from 2010 to 2026, including mechanistic, in vitro, biofilm, preclinical, clinical, and formulation studies addressing medicinal plants, isolated phytochemicals, and plant-derived oral healthcare products. We examine how these interventions may influence oral health through mechanisms extending beyond direct bacterial killing. We synthesise evidence on major phytochemical classes, including polyphenols, terpenoids, alkaloids, sulfur compounds, and glycosides, together with their effects on biofilms, quorum sensing, inflammation, oxidative stress, and tissue repair. We also assess clinical evidence for botanical formulations and emerging delivery systems designed to improve stability and local retention. Current evidence indicates that several plant-derived compounds can inhibit biofilm formation, interfere with bacterial virulence, modulate inflammatory signalling, and support tissue recovery. Green tea, pomegranate, cranberry, turmeric, neem, aloe vera, mangosteen, and propolis show promising clinical or experimental activity, although evidence strength varies considerably among plants and formulations. Nanoemulsions, lipid-based carriers, and mucoadhesive systems may improve phytochemical stability and local exposure, but clinical validation remains limited. Overall, phytotherapy appears most useful as an adjunct to established oral hygiene rather than a replacement for conventional care. Standardized extracts, well-characterized formulations, microbiome-based outcomes, long-term clinical trials, and clearer regulatory pathways remain essential before wider clinical adoption.
