Anti-inflammatory, anti-diabetic, and biocompatibility properties of aqueous extract of Tamarindus indica L. fruit coat analyses by in-vitro and in-vivo approaches

The anti-inflammatory, anti-diabetic, and biocompatibility nature of Tamarindus indica L. fruit coat aqueous extract were investigated in this research through in-vitro and in-vivo studies. The anti-inflammatory property was determined through albumin denaturation inhibition and antiprotease activities as up to 39.5% and 41.2% respectively at 30 mg mL-1 concentration. Furthermore, the antidiabetic activity was determined through α-amylase and α-glucosidase inhibition as up to 62.15% and 67.35% respectively at 30 mg mL-1 dosage. The albino mice based acute toxicity study was performed by different treatment groups (group I-V) with different dosages of aqueous extract to detect the biocompatibility of sample. Surprisingly, findings revealed that the T. indica L. fruit coat aqueous extract had no harmful impacts on any of the groups. Urine, as well as serum parameter analysis, confirmed this. Moreover, the findings of SOD (Superoxide Dismutase), GST (Glutathione-S-transferase), & CAT (Catalase) as well as glutathione peroxidase as well as reduced glutathione antioxidant enzymes studies stated that the aqueous extract possess high antioxidant ability via a dose-dependent way. These findings indicate that T. indica fruit coat aqueous extract contains medicinally important phytochemicals with anti-inflammatory and anti-diabetic properties, as well as being biocompatible in nature.

Assessment of antidiabetic, anti-inflammatory, antioxidant and anticancer activity competence of methonolic extracts of Trianthema ortulacastrum and Andrographis paniculata

An in-vitro investigation was performed to evaluate and compare the phytochemical, antioxidant, antidiabetic, anti-inflammatory, and anti-lung cancer activities of methanol extracts of aerial parts of Andrographis paniculata and Trianthema portulacastrum. Furthermore studied major functional groups of phytochemicals present in the methanol extracts of these plants through Fourier transform infrared (FTIR) analysis. The results showed that the methanol extract of A. paniculata contain more number of pharmaceutically valuable phytochemicals such as alkaloids, flavonoids, terpenoids, saponin, glycoside, phytosterol, and tannin than T. portulacastrum. Similar way the methanol extract of A. paniculata showed considerable dose dependent antioxidant (DPPH: 63%), antidiabetic (α-amylase: 82.31% and α-glucosidase inhibitions: 72.34%), and anti-inflammatory (albumin-denaturation inhibition: 76.3% and anti-lipoxygenase: 61.2%) activities (at 900 μg mL-1 concentration) than T. portulacastrum. However, the anti-lung cancer activities of these test plants against A549 cells were not considerable. According to FTIR analysis, the A. paniculata methanol extract has a larger number of characteristic peaks attributed to the active functional groups of pharmaceutically valuable bioactive components that belong to different types of phytochemicals. These findings imply that A. paniculata methanol extracts can be used for additional research, such as bioactive compound screening and purification, as well as assessing their potential biomedical uses in various in-vitro and in-research settings.

An In Vitro Evaluation of the Antibacterial Efficacy of Solanum xanthocarpum Extracts on Bacteria From Dental Plaque Biofilm

OBJECTIVE

The focus of research has recently shifted toward developing herbal-based medicines due to the emerging bacterial resistance and side effects of antibiotics. Solanum xanthocarpum (Sx) is a medicinal plant with potent pharmacological properties. This study aimed to evaluate the antibacterial activity of its crude extracts on bacteria isolated from dental plaque in patients with gingivitis.

MATERIALS AND METHODS

Aqueous, ethyl acetate, hexane, chloroform, and ethanolic extracts were prepared from Sx. Dental plaque samples were collected from patients with plaque-induced gingivitis. Disk diffusion assay was performed to determine the antibacterial activity of the extracts at concentrations of 25 mg/ml, 50 mg/ml, and 75 mg/ml with ampicillin 200 mg/ml as a positive control. The minimum inhibitory concentration (MIC) of the aqueous extract was also evaluated by broth dilution test against bacteria isolated from dental plaque biofilm.

RESULTS

The antibacterial activity was estimated by measuring the zones of inhibition through the disc diffusion method. The Kruskal Wallis with Dunn post hoc test performed for intergroup comparison between the various extracts showed a statistically significant difference in inhibition of bacterial growth between 25 mg/ml and 75 mg/ml concentrations. There was no significant difference between the 75 mg/ml Sx concentration and the positive control. In addition, the MIC was elucidated to be 0.625 g/ml, at which there was maximum inhibition of bacterial growth.

CONCLUSION

The Sx extract exhibited antibacterial activity against periodontal pathogens. Thus, it can be concluded that optimum concentrations of Sx could be used in therapeutic strategies to prevent and manage periodontal diseases.

In-situ production of iron flocculation and reactive oxygen species by electrochemically decomposing siderite: An innovative Fe-EC route to remove trivalent arsenic

The removal of trivalent arsenic (As (III)) from water has received extensive attention from researchers. Iron electrocoagulation (Fe-EC) is an efficient technology for arsenic removal. However, electrode passivation hinders the development and application of Fe-EC. In this work, an innovative Fe-EC route was developed to remove As (III) through an electrochemical-siderite packed column (ESC). Ferrous ions were produced from siderite near the anode, and hydroxide was generated near the cathode during the electrochemical decomposition of siderite. As a result, an effect of Fe-EC-like was obtained. The results showed that an excellent removal performance of As (III) (>99%) was obtained by adjusting the parameters (As (III) concentration at 10 mg/L, pH at 7, Na₂SO₄ at 10 mM and the hydraulic retention time at 30 min) and the oxidation rate of As (III) reached 84.12%. The mechanism analysis indicated that As (III) was oxidized to As (Ⅴ) by the produced active oxide species and electrode, and then was removed by capturing on the iron oxide precipitates. As (III) was likely to be oxidized in two ways, one by the reactive oxygen species (possibly •OH, Fe(IV) and •O₂^- species), and another directly by the anode. The long-term effectiveness of arsenic removal demonstrated that ESC process based on the electrochemical-siderite packed column was an appropriate candidate for treating As (III) pollution.

Unravelling the potential plant growth activity of halotolerant Bacillus licheniformis NJ04 isolated from soil and its possible use as a green bioinoculant on Solanum lycopersicum L

Immensely expanding world population and narrowing arable land for agriculture is a mighty concern faced by the planet at present. One of the major reasons for decline in arable lands is the increased soil salinity, making it unfavourable for crop cultivation. Utilisation of these saline land for agriculture is possible with suitable invention for improving the soil quality. Biofertizers manufactured out of Plant Growth Promoting Rhizobacteria is one such innovation. In the present study, Bacillus licheniformis NJ04 strain was isolated and studied for its halotolerance and other effective plant growth promoting traits. The NJ04 strain was able to tolerate salt up to 10% and highlighted remarkable antifungal activity against common fungal phytopathogens. The preliminary seed germination test in Solanum lycopersicum seeds revealed a significant increase in root length (16.29 ± 0.91 cm) and shoot length (9.66 ± 0.11 cm) of treated plants as compared with the control plants and thereby shows its possible use as a green bioinoculant in agriculture and an ideal candidate to compete with salt stress.

Cannabis sativa L. protects against oxidative injury in kidney (vero) cells by mitigating perturbed metabolic activities linked to chronic kidney diseases

ETHNOPHARMACOLOGICAL RELEVANCE

Cannabis sativa L. is among numerous medicinal plants widely used in traditional medicine in treating various ailments including kidney diseases.

AIMS

The protective effect of C. sativa on oxidative stress, cholinergic and purinergic dysfunctions, and dysregulated glucogenic activities were investigated in oxidative injured kidney (Vero) cell lines.

METHODS

Fixed Vero cells were treated with sequential extracts (hexane, dichloromethane [DCM] and ethanol) of C. sativa leaves for 48 h before subjecting to MTT assay. Vero cells were further incubated with FeSO₄ for 30 min, following pretreatment with C. sativa extracts for 25 min. Normal control consisted of Vero cells not treated with the extracts and/or FeSO₄, while untreated (negative) control consisted of cells treated with only FeSO₄.

RESULTS

MTT assay revealed the extracts were slightly cytotoxic at the highest concentrations (250 μg/mL). There was a significant depletion in glutathione level and catalase activity on induction of oxidative stress, with significant elevation in malondialdehyde level, acetylcholinesterase, ATPase, ENTPDase, fructose-1,6-biphosphatase, glucose 6-phosphatase and glycogen phosphorylase activities. These activities and levels were significantly reversed following pretreatment with C. sativa extracts.

CONCLUSION

These results portray the protective potentials of C. sativa against iron-mediated oxidative renal injury as depicted by the ability of its extracts to mitigate redox imbalance and suppress acetylcholinestererase activity, while concomitantly modulating purinergic and glucogenic enzymes activities in Vero cells.
