Conclusion: The findings suggest that the hydroalcoholic extract of Nasturtium Officinale does not appear to improve sleep quality, asthma control, and quality of life in asthmatic patients in the short term.

Reversal of high-fat diet-induced cognitive impairment and oxidative stress in the brain through Zingiber officinale supplementation.

Obesity is a significant health concern that is correlated with various adverse health outcomes. Diet-induced obesity (DIO) is associated with impaired cognitive function. Pharmacological treatments for obesity are limited and may have serious adverse effects. Zingiber officinale (ZO) has anti-inflammatory and antioxidant effects, in addition to metabolic effects. This study aimed to assess the effects of Zingiber officinale supplementation on cognitive function, anxiety levels, neurotrophin levels, and the inflammatory and oxidative status in the cortex following DIO in mice. Two-month-old male Swiss mice were fed DIO or standard chow for 4 months and subsequently subdivided into the following groups (n = 10 mice/group): (i) control - vehicle (CNT + vehicle); (ii) CNT supplemented with ZO (CNT + ZO); (iii) obese mice (DIO + vehicle); and (iv) obese mice supplemented with ZO (DIO + ZO) (n = 10). Zingiber officinale extract (400mg/kg/day) was administered for 35 days via oral gavage. The DIO + vehicle group exhibited impaired recognition memory. The CNT + ZO group presented a greater number of crossings in the open field. No difference between the groups was observed in the plus maze test. DIO + vehicle increased the DCFH and carbonylation levels in the cortex. The DIO + vehicle group presented a reduction in catalase activity. The expression of inflammatory or neurotrophin markers in the cerebral cortex was not different. In conclusion, our findings indicate that supplementation with ZO reverses the cognitive impairment in DIO mice and enhances the antioxidant status of the cerebral cortex.

Green synthesis of copper oxide nanoparticles using Rosmarinus officinalis leaf extract and evaluation of its antimicrobial activity

Due to the development of green technology, researchers are becoming more interested in low-cost, environmental eco-friendly methods for the synthesis of nanoparticles (Nps). In this work, Copper oxide nanoparticles (CuO Nps) were synthesized using a green synthesis technique, with Rosmarinus officinalis leaf extract acting as a capping and reducing agent. The as prepared the samples was characterized using UV-Visible Spectra (UV–VIS), X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR), and Scanning Electron Microscopy (SEM). The UV-Visible spectra result showed that strong absorption was observed for characteristic band of green synthesized CuO Nps and exhibit red shift as the weight fraction of CuO Nps increases. The XRD analysis confirmed the formation of CuO Nps, having a typical monoclinic structure with crystalline size ranging from 18 to 26 nm. From FTIR spectral analysis strong and broad peak observed at 3384 cm−1 can be attributed to (O-H) functional groups of the bioactive compounds which act as reducing and capping agents for the synthesis of CuO Nps in the plant extract. The SEM images of green synthesized CuO NPs was appeared to be aggregated form and almost spherical in shape. The antimicrobial activity of CuO Nps was evaluated against S.aureus and B.cereus (gram-positive), E. coli (gram-negative) bacteria strains and C.albicans fungal Pathogen. The result indicated that at weight fraction of 50 %, CuO Nps exhibit highest antimicrobial activity against E. coli, S. aureus, C.albicans and B.cereus with zone of inhibition of 26.0 ± 0.10, 25.0 ± 0.15, 18.1 ± 0.32 and 17.0 ± 0.0 mm respectively. Furthermore, for the E. coli bacterial strain, the minimum inhibitory concentration (MIC) of CuO Nps was found to be 1.56 mg/mL; whereas, for S. aureus and C. albicans was found to be 3.12 mg/mL. Therefore, the present study shows that Rosmarinus officinalis extract can be easily used as a reducing, stabilizing, and capping agent for the effective green synthesis of CuO Nps for antimicrobial agents. Thus, it is believed that synthesis of nanoparticles using low cost and eco-friendly green approach enhanced the antimicrobial activity and other a potentially applications in fields of biomedical.

Safety and effect of a new artificial saliva containing Zingiber officinale and Cuminum cyminum on stimulating saliva secretion: In vitro, in vivo and preliminary clinical study

IntroductionXerostomia is a symptom that affects quality of life and may lead to malnutrition. While artificial saliva is used as a lubricant for the oral cavity, it rarely stimulates saliva secretion. The objective of this study was to develop a herbal artificial saliva (HAS) that could stimulate saliva secretion and be safe for human consumption. MethodsThree HAS formulations were prepared with 0.3 % Cuminum cyminum extract and 0.05 %, 0.10 %, and 0.15 % Zingiber officinale extract (HAS0.05, HAS 0.10, and HAS0.15, respectively). In vivo skin and oral mucosal irritation tests were used to evaluate the safety of HAS0.15. Additionally, the preliminary efficacy and safety of the three HAS formulations were investigated in 21 healthy volunteers. The sample was sprayed into the oral cavity under the left and right sides of the tongue. Thirty minutes after spraying, the amount of saliva was assessed using a visual analogue scale and a Schirmer strip. In addition, dry mouth symptoms, the saliva pH, and adverse reactions were assessed before and after testing. ResultsHAS0.15 caused minimal skin irritation and did not alter the epithelium or other structures of the oral mucosa. The saliva quantity after using HAS0.10 and HAS0.15 was significantly higher than prior to testing (p < 0.05). None of the formulations induced mucositis or adverse reactions. ConclusionThis study was successful in the development of a new HAS that stimulated saliva secretion and was safe for humans. However, this study is preliminary: Further clinical investigation in patients with hyposalivation will confirm the efficacy of this novel HAS. This novel HAS may be an alternative treatment for the elderly and patients with hyposalivation.

Enhancing antibacterial activity through green synthesis of silver nanoparticles with salvia officinalis extracts

This study aimed to test the effectiveness of water-based extracts and green-synthesized silver nanoparticle extracts from the Salvia officinalis plant in killing bacteria. We used the agar well diffusion method to see how well these extracts could fight against both Gram-positive bacteria (Staphylococcus epidermidis and Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa). To understand the properties of the nanoparticles, we analyzed them using a UV-VIS spectrophotometer and a scanning electron microscope (SEM). The results showed that both types of extracts were effective against the bacteria, with performance similar to the antibiotic chloramphenicol used as a benchmark. An interesting finding was that combining the plant extracts with the antibiotic or the silver nanoparticle extract with the antibiotic significantly enhanced the ability to stop bacterial growth in all tested strains. The Gram-positive bacteria were more affected than the Gram-negative ones, suggesting a potential way to overcome bacterial resistance.

Immunohistochemical results demonstrated that the extract reduced Ki-67 and α-SMA expression and Masson’s trichrome staining revealed decreased liver collagen in rats treated with Levisticum officinale extract. Moreover, Levisticum officinale extract markedly decreased the gene expressions of TNF-α, 1L-6, TGF-β1, MCP-1, and COX-2. Conclusions: Levisticum officinale extract exerts hepatoprotective effects on CCl4-induced hepatotoxicity through antioxidant, anti-inflammatory, and anti-fibrotic activities.

Ameliorative Effect of Zingiber officinale Ethanol Extract on Chromium-induced Male Reprotoxicity in Wistar Rat

This study explored the protective effects of oral ginger extract against chromium trioxide (CrO3)-induced male reprotoxicity in Wistar albino rats. Rats exposed to CrO3 for 8 weeks showed significant declines in body weight (11.67 ± 3.78 g), serum testosterone levels (6.45 ± 1.35 ng/mL), Glutathione (GSH) level (17.29 ± 1.96 μM/mg), and catalase activity (9.54 ± 0.11 mM H2O2/min/mg), with no notable change in relative testicular weight. Conversely, ginger extract-treated rats exhibited substantial improvements, including increased body weight (45.33 ± 09.11 g), enhanced GSH levels in testicular tissue (24.02 ± 1.69 μM/g), and improved catalase activity (11.56 ± 1.25 mM H2O2/min/mg). However, concurrent CrO3 and Z. officinale extract treatment showed no significant changes in testosterone levels. Z. officinale extract, due to its high content of polyphenols (194.82 ± 8.57 mg GAE/g d.w.), and flavonoids (117.20 ± 48.61 mg CE/g d.w.) with significant antioxidant value (IC50 = 0.57 ± 0.14 mg/ml), showed a remarkable ameliorative effect against chromium-induced male reprotoxicity.

Conclusion: The tests for the detection of the active groups of the extracts showed that they are affected by the nature of the solvent in terms of polarity, which affects the type and concentration of the groups extracted and the nature of the extraction, The toxicity test results showed that the aqueous and alcoholic extracts were non-toxic, the results of the antioxidant activity test showed that the alcoholic extract of the sage plant is more effective than the aqueous extract.

Newly Developed Semi-Solid Formulations Containing Mellilotus officinalis Extract: Characterization, Assessment of Stability, Safety, and Anti-Inflammatory Activity.

Melilotus officinalis has been traditionally used as an anti-inflammatory agent; nevertheless, a comprehensive evaluation of its efficacy and safety and comparison with standard drugs are lacking. Taking into consideration concerns with current therapies, like efficacy limitations, side effects, and resistance, we aimed to develop a natural gel and cream based on Melilotus officinalis extract and explore their anti-inflammatory potential. After the chemical analysis of the extract confirmed the presence of coumarin, p-coumaric acid, gallic acid, and quercetin, formulations were prepared and subjected to physical and chemical stability evaluations over 6 months. The safety potential was tested in rats, while the anti-inflammatory activity was assessed both via in silico tests and in a rat model of inflammation. The examined formulations showed stable physical characteristics at the defined storage conditions and did not exert any sign of adverse skin reaction. The gel formulation exhibited a remarkable effect in inflammation reduction comparable with hydrocortisone. The in silico results suggest that coumarin, p-coumaric, and gallic acid bind to COX-1 and COX-2 with a lower affinity compared to diclofenac. On the other hand, quercetin demonstrated comparable inhibitory activity and stronger interaction compared to the control drug. Our results indicate that the examined formulations are stable and safe and may be promising dermal products for the alleviation of inflammatory skin conditions.

Exploring Conventional and Green Extraction Methods for Enhancing the Polyphenol Yield and Antioxidant Activity of Hyssopus officinalis Extracts.

Hyssopus officinalis L. (HO) is, as one of the most prevalently utilized plants, used in traditional medicine to cure various diseases as well as the in food and cosmetic industries. Moreover, HO is a rich source of polyphenols with potent antioxidant properties. However, the studies on the extraction of such compounds from HO are scanty and sparse. This study aims to optimize the extraction of polyphenols and maximize the antioxidant activity in HO extracts. A comprehensive experimental design was employed, encompassing varied extraction parameters to determine the most effective ones. Alongside conventional stirring (ST), two green approaches, the ultrasonic treatment (US) and the pulsed electric field (PEF), were explored, either alone or in combination. The extracted polyphenolic compounds were identified with a high-performance liquid chromatography-diode array detector (HPLC-DAD). According to the results, the employment of ST along with an ethanolic solvent at 80 °C for 150 min seems beneficial in maximizing the extraction of polyphenols from HO, resulting in extracts with enhanced antioxidant activity. The total polyphenol was noted at 70.65 ± 2.76 mg gallic acid equivalents (GAE)/g dry weight (dw) using the aforementioned techniques, and the antioxidant activity was noted as 582.23 ± 16.88 μmol ascorbic acid equivalents (AAE)/g dw (with FRAP method) and 343.75 ± 15.61 μmol AAE/g dw (with the DPPH method). The as-prepared extracts can be utilized in the food and cosmetics industries to bestow or enhance the antioxidant properties of commercial products.

Rosemary officinalis extract mitigates potassium dichromate-induced testicular degeneration in male rats: Insights from the Nrf2 and its target genes signaling pathway

This study aimed to investigate the protective effects of Rosemary ethanol extract (ROEE) on testicular damage induced by potassium Dichromate (PDC) in male rats regarding the signaling pathway of Nrf2 and its target genes and proteins. A total of 28 male rats were divided into four groups: control, PDC only (15 mg/kg b.w. orally), PDC + low dose ROEE (220 mg/kg b.w.), and PDC + high dose ROEE (440 mg/kg b.w.). After 28 days of consecutive treatment, the rats were sacrificed for histological, immunohistochemistry, and biochemical analyses. The results revealed that the ROEE treatment up-regulated the Nrf2 and its target genes (NQO1, HO-1) mRNA expressions compared to the PDC group. correspondingly, the protein levels of GCLM, GSH, SOD, and catalase were significantly increased in the ROEE-treated animals compared to the PDC-treated animals. Furthermore, ROEE administration led to increased serum levels of testosterone (T4) and decreased levels of estrogen (E2) compared to the PDC group. Semen analysis and histopathology demonstrated that ROEE administration significantly improved spermatological impairment caused by PDC. The immunoexpression of cytoplasmic HSP-90 was reduced in the ROEE-treated groups, while the expression of androgen receptor (AR) was markedly improved. ROEE exhibited protective effects against PDC-induced testicular damage, likely due to its antioxidant properties. However, further investigation is required to elucidate the underlying mechanisms of action.

Composite Coatings with Liposomes of Melissa officinalis Extract for Extending Tomato Shelf Life

In this study, active coatings based on carboxymethylcellulose (CMC) were prepared using liposomes filled with an aqueous extract of Melissa officinalis retained in high acyl gellan gum (HAG), low acyl gellan gum (LAG), and their mixture (HAG/LAG). The objective was to investigate the effect of these coatings on postharvest preservation of tomato (Solanum lycopersicum) fruits. The tomato fruits were divided into four groups: (i) coating with HAG-based liposomes (WL-HAG), (ii) coating with LAG-based liposomes (WL-LAG), (iii) coating with HAG/LAG-based liposomes (WL-HAG/LAG), and (iv) control group treated with sterile water. Over a period of 10 days, various quality attributes, such as respiration rate, soluble solids, titratable acidity, luminosity, weight loss, malondialdehyde (MDA) content, hydrogen peroxide, total phenols, and DPPH scavenging ability, were studied. The results indicated that the WL-HAG coatings significantly (p &lt; 0.05) decreased the respiration rate, hydrogen peroxide, and MDA content compared to the control fruits and other coatings. Therefore, WL-HAG could be considered a promising option to enhance postharvest preservation of tomato fruits in the Colombian fruit and vegetable industry.

Saponin and Phenolic Composition and Assessment of Biological Activities of Saponaria officinalis L. Root Extracts.

The purpose of this study was to identify the saponin and phenolic components in root extracts of Saponaria officinalis, a widespread species, found in Cyprus. A total of six major saponins, including gypsogenin and gypsogenic acid derivatives, as well as saponariosides C, D, and E, were identified using UHPLC/Q-TOF-MS analysis, with gypsogenin derivatives being the most common saponins detected through quantitative analysis. A total of six phenolic compounds were also identified, including rutin, quercetin galactoside, syringic acid, apigenin, protocatechuic, and vanillic acid. In addition to their saponin and phenolic contents, the root extracts were prepared through different extraction methods, and their biological activity was assessed. All samples demonstrated antioxidant capacity, as well as antibacterial activity, against four bacterial strains (Escherichia coli, Staphylococcus aureus, Enterococcus faecalis, and Salmonella enteritidis), with the acetone extract presenting higher susceptibility. The evaluation of anticancer activity in A375 (human malignant melanoma), HeLa (human cervical epithelioid carcinoma), and HaCaT (healthy human keratinocytes) cell lines revealed that the acetone extract of S. officinalis extract demonstrated a significant inhibitory effect on the proliferation of A375 cells in a concentration-dependent manner. None of the extracts demonstrated anti-neurotoxic potential against Aβ25-35 cytotoxic peptides. The results of this study support previous findings that reveal that the Saponaria species are an excellent natural source of biologically active compounds with antioxidant, antimicrobial, and anticancer properties.

Methodology: Two weeks of acclimatized healthy fish were divided into four different groups. Group G1 served as the control group, while G2 contained chlorpyrifos (LC50/10, 96 hr). Group G3 was exposed to chlorpyrifos (LC50/10, 96 hr) along with 8 mg l-1 of Melissa officinalis ethanolic extract, and similarly, G4 contained chlorpyrifos (LC50/10, 96 hr) along with 8 mg l-1 ethanolic extract of Mentha piperita. Sampling was conducted over various durations of 7, 14, 21, and 28 days. The ethanolic extracts of Melissa officinalis and Mentha piperita were used as remedial compounds as they are rich in several bioactive compounds, primarily polyphenols. Results: The investigation revealed a notable decrease in the total protein content of kidney, liver, gills and muscles following exposure to chlorpyrifos after each sampling duration. While, upon exposure to remedies containing the ethanolic extracts of Melissa officinalis and Mentha piperita, the protein levels exhibited a significant recovery (p &lt; 0.05) in a duration-dependent manner, compared to the control group. This suggests a promising ameliorative capability of Melissa officinalis and Mentha piperita against chlorpyrifos toxicity. Further, the induction of micronuclei by chlorpyrifos and their subsequent recovery through the application of phytoextracts Melissa officinalis and Mentha piperita displayed a similar pattern, indicating the potential protective effects of these extracts against chlorpyrifos-induced genotoxicity. Interpretation: It is plausible to conclude that standardized doses of Melissa officinalis and Mentha piperita hold the potential to enhance aquaculture practices and safeguard fish production in agriculturally contaminated water bodies. These findings emphasize their valuable contribution in sustaining fish health amidst toxic environments. Key words: Channa punctatus, Chlorpyrifos, Melissa officinalis, Mentha piperita

Evaluation of the acute and sub-acute toxicity of the standardized extract of Avicennia officinalis L. in mice

Avicennia officinalis L. (AOL) has shown promise for its anti-inflammatory, anti-cancer, and antioxidant properties. However, there is no research on the toxicity of this plant in Vietnam. The acute and sub-acute toxicology study proved that AOL leaf extracts are practically non-toxic in normal mice. Acute toxicity assessment was conducted with single oral doses of AOL extract (2500, 3100, 4100, and 5000 mg/kg). In sub-acute toxicity, mice were administered daily oral doses of AOL extract (200 and 400 mg/kg) for 28 days. Blood was collected from the heart, liver, and kidneys for further analysis. The comprehensive results revealed an oral median lethal dose (LD50) exceeding 5000 mg/kg, indicating low acute toxicity. A sub-acute study (200 and 400 mg/kg/day) showed no deaths or weight gain. At both doses, the standardized AOL extracts decreased serum aspartate transaminase activity. Administration of the 200 mg/kg group significantly increased blood urea levels; however, histological examination of mouse kidneys in this group revealed no signal of damage. Histological examination of mouse livers revealed mild degeneration, possibly due to the use of adult mice and potentially unrelated to the extract. This study emphasizes AOL's potential for further pharmacological testing based on its low acute toxicity and promising results.
