Background/Objectives: Eucalyptus globulus is a medicinal plant extensively used by the Moroccan population for treating a range of illnesses, especially respiratory conditions. Methods: This study aimed to assess the antioxidant and antibacterial properties of E. globulus essential oil and its individual fractions (F1, F2, and F3). Antioxidant activity was evaluated through iron-reducing power, 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays. Antibacterial activity was tested using disk diffusion and dilution methods, supported by molecular docking studies. Furthermore, GC–MS analysis was conducted on the essential oil and its individual fractions. Results: GC–MS analysis identified the major compounds in the essential oil and its fractions as eucalyptol (62.32–42.60%), globulol (5.9–26.24%), o-cymene (6.89–24.35%), cryptone (7.10–15.95%), terpinen-4-ol (2.43–15.24%), and α-pinene (2.46–7.89%). Fraction F3 displayed the highest antioxidant activity in DPPH (IC₅₀ = 3.329 ± 0.054 mg/mL) and ABTS assays (IC₅₀ = 3.721 ± 0.027 mg/mL), while fraction F2 was most effective in the FRAP assay (IC₅₀ = 1.054 ± 0.008 mg/mL). The essential oil and its fractions also showed antibacterial activity against Staphylococcus aureus, Staphylococcus epidermidis, Klebsiella pneumoniae, Enterobacter cloacae, Escherichia coli, and Acinetobacter baumannii. Molecular docking further corroborated these findings, supporting both antioxidant and antibacterial activities. Conclusions: The present findings demonstrate the antioxidant and antimicrobial properties of Eucalyptus globulus essential oil and its fractions, underscoring the need for further research to confirm their medicinal potential and explore pharmaceutical applications.

Cynara humilis is traditionally used to treat skin burns and microbial infections. However, experimental studies on this plant are rare. Furthermore, the aim of this study was to investigate the effects of Cynara humilis, a Moroccan herbal remedy, on the healing of deep second‐degree burns in rats with a silver sulfadiazine group. This research was also carried out to confirm if C. humilis had antibacterial capabilities. Under typical burn procedures, each rat received a deep second‐degree burn on the upper back. The burns were treated regularly with control groups (control and control VH), silver sulfadiazine (SDD) in group 3, C. humilis ethanolic extract (CHEE) in group 4, and C. humilis aqueous extract (CHAE) in group 5. Throughout the treatment, digital photography was used to measure rat responses to the treatment until day 18. After the scar biopsy at the end of the study, histological parameters (inflammatory cells, collagen, epithelialization, fibrosis, and granulation tissue) were assessed. Using the well technique, the antibacterial activity of the extracts was tested against Staphylococcus aureus CIP 483, Bacillus subtilis CIP 5262, Escherichia coli CIP 53126, Pseudomonas aeruginosa CIP 82118, and Salmonella enterica CIP 8039, and the results showed important activities of the ethanolic and aqueous extracts against the five species tested with MICs of 2 and 4 mg/mL, respectively. In the aqueous extract group, the wound healed faster. In addition, the healing rate in the C. humilis extracts (CHEA and CHEE) group was faster than in the silver sulfadiazine and control groups. In the C. humilis group, maximum wound surface recovery was observed at the same time, as it was not noted in the silver sulfadiazine group. Pathologically, epithelialization was more marked in wounds treated with C. humilis extracts (CHE). Angiogenesis and inflammatory cells were considerably lower in the CHE group than in the silver and other control groups. However, elastic fibers were considerable in the CHE‐treated group. In histological examination, the C. humilis group had a low incidence of angiogenesis and inflammation, indicating that this group had less wound scarring. Collagen and burn wound healing were both faster in the C. humilis group. The findings of this study suggest that C. humilis, as indicated by traditional medicine, is a promising natural source for the management of wound healing.

Lawsonia inermis, commonly known as Henna, is a plant that has been extensively utilized throughout the ages for its medicinal and cosmetic properties. This plant contains a variety of bioactive compounds and has attracted significant interest due to its potential antioxidant and antimicrobial activities. The aim of our study is to evaluate the antioxidant capacity and antibacterial activity of Lawsonia inermis seeds. L. inermis seed powder was extracted using hexane, dichloromethane, ethanol and water. The 4 fractions were quantified for polyphenols, flavonoids and tannins contents. The antioxidant capacity was assessed using 4 methods: 2,2?-Diphenyl- picrylhydrazyl hydrate (DPPH) , 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic) (ABTS), Ferric Reducing Antioxidant Power (FRAP), and Phosphomolybdate assay (PMA). Antimicrobial activity was determined by agar diffusion against Staphylococcus aureus, Bacillus cereus, Enterococcus faecalis, Escherichia coli, Pseudomonas aeruginosa and Candida albicans. The liquid dilution method was used to determine the minimum inhibitory concentration, minimum bactericidal concentration and minimum fungicidal concentration. The highest content of polyphenols and tannins was obtained in the ethanolic fraction, with values of 594.01±6.07 mg GAE/g dw and 242.4±1.6 mg CE/g dw respectively. The ethanolic fraction exhibited significant scavenging of free radicals (DPPH) with an IC50 of 3.06±0.01 µg/mL, lower than the IC50 of the standard quercetin (5.30±0.02 µg/mL). Moreover, the ethanolic fraction showed antimicrobial activity against S. aureus, B. cereus and E. faecalis strains, with zone of inhibition values of 15.5±0.7, 14.0±0.0 and 14.5±0.7 mm respectively. The minimum inhibitory concentration of the ethanolic fraction was found to be 1.563 mg/mL against both S. aureus and B. cereus strains, while the minimum bactericidal concentration was 3.125 mg/mL against B. cereus and 6.25 mg/mL against E. faecalis strains. L. inermis seeds exhibit significant antioxidant capacity and demonstrate antimicrobial activity. These findings indicate the potential of L. inermis seeds as a valuable source of bioactive compounds with antioxidant and antimicrobial properties.

Pain and inflammation are common symptoms present in many medical conditions, typically managed with analgesic and anti-inflammatory medications. However, these medications, whether targeting peripheral or central pathways, are often associated with adverse side effects. This study aimed to identify the constituents of Lawsonia inermis seed fractions, and evaluate the analgesic, and anti-inflammatory activities of these fractions. Chemical constituents of the fractions were characterized using high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The analgesic properties were evaluated using the acetic acid-induced writhing and tail immersion tests, while anti-inflammatory activity was assessed via the carrageenan-induced paw edema model in mice. A total of 29 compounds were identified, with the ethanol fraction exhibiting the highest concentration of the constituents, amounting to 93.89 mg/g fraction. Major compounds detected in the ethanol fraction included gallic acid, catechin, tannic acid, vanillin, epicatechin gallate, isoquercitrin, and ellagic acid. The study revealed that the ethanol fraction demonstrated a notable peripheral analgesic effect, achieving 34.75% inhibition at a dose of 250 mg/kg in mice, while the aqueous fraction showed substantial central analgesic activity in rats at 500 mg/kg throughout the experimental period. Additionally, at a dose of 400 mg/kg, the ethanol fraction resulted in a 74.05% inhibition of inflammation in mice, outperforming indomethacin, which achieved a 58.09% inhibition at 10 mg/kg after 4 h. These findings present novel evidence that the fractions of L. inermis seed exhibit significant analgesic and anti-inflammatory activities, supporting the traditional medicinal use of this plant for the management of conditions involving pain and inflammation.
