AbstractBackgroundThe most prevalent probiotic bacterium employed in the food industry is Lactobacillus because it can produce metabolites with antibacterial capabilities and exhibits hostility towards infections and microorganisms that cause spoilage.AimThis study set out to identify naturally occurring Lactobacillus and plantaricin (pln EF) coding genes in raw cow milk and to assess the antibacterial potency of isolated Lactobacillus isolates.MethodsFollowing enrichment in De Man, Rogosa and Sharpe (MRS) broth, single colonies were isolated, and pure colonies were obtained by streaking on MRS agar. The 16S rRNA gene was amplified using polymerase chain reaction (PCR) to confirm the cultural positivity of all isolates. Additionally, the presence of plantaricin was verified by targeting the pln EF gene through PCR.OutcomeOut of the 166 raw milk specimens acquired from cows, 153 (91.17%; CI: 86.98–95.76) were identified as positive for Lactobacillus through both culture and biochemical screening. Subsequently, 121 (72.89%; CI: 65.46–79.49) of the isolates were affirmed to harbour Lactobacillus through PCR analysis. Within this subset, 6 isolates (4.96%; CI: 1.84–10.48) were found to possess the plnEF gene. When exposed to Lactobacillus isolates, Salmonella Typhimurium and Salmonella enterica displayed an average maximum zone of inhibition with a diameter measuring 24 mm. In contrast, Escherichia coli exhibited an average minimum zone of inhibition, featuring a diameter of 11 mm. Additionally, the Lactobacillus isolates demonstrated inhibitory zones against Staphylococcus aureus, Klebsiella pneumoniae and Klebsiella oxytoca, measuring 14, 22 and 19 mm, respectively.Clinical significanceLactic acid bacteria, particularly Lactobacilli, are plentiful in cow milk and possess broad‐spectrum antibacterial properties.

AbstractThis study focused to assess the efficacy of Gynura procumbens (GP) leaf extract against cisplatin (CP)‐induced hepatorenal complications in Wister albino rats. Additionally, it aims to detect polyphenolic compounds using high‐performance liquid chromatography with diode‐array detection (HPLC‐DAD). The rats were treated intraperitoneally with CP (7.5 mg/kg) to mediate hepatorenal damage. They were then treated with GP extract (75 and 150 mg/kg, P.O.) for 7 consecutive days. Although GP extract significantly ameliorated CP‐mediated hepatorenal biomarkers like alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine, and blood urea nitrogen (BUN) levels in a dose‐dependent manner, GP extract at 150 mg/kg dose normalized hepatorenal biomarkers ALP (45.11 U/L), ALT (34 U/L), AST (29 U/L), creatinine (10.3 mg/dl) and BUN (11.19 mg/dl) while comparing to control and disease group. Similarly, though it significantly reduced CP‐induced oxidative stress inducers, including nitric oxide (NO) and advanced oxidative protein products (AOPP), higher dose (150 mg/kg) exhibited better activity in reducing NO (281.54 mmol/gm tissue in liver and 52.73 mmol/gm tissue in the kidney) and AOPP (770.95 mmol/mg protein in liver and 651.90 mmol/mg protein in the kidney). Besides, it showed better enhancement in the antioxidant enzymes superoxide dismutase, and glutathione levels at a higher dose (150 mg/kg). Histopathological studies showed that CP caused collagen accumulation in the liver and kidney tissues. GP extract drained the collagen mass and acted against hepatorenal damage. Ellagic acid, gallic acid, quercetin hydrate, kaempferol, and rutin hydrate were revealed in GP extract. In‐silico modelling showed good docking scores of the polyphenolic compounds with molecular targets including CYP4502E1, NF‐κB, caspase‐3, and TNF‐α. GP could be an effective therapeutic option for management of anticancer drugs’ complications like CP‐induced organ damage, although clinical studies are required to establish herbal formulation.

Zingiber roseum (Roxb.) Roscoe, a perennial herb from the Zingiberaceae family, has a long history of traditional use in the treatment of several ailments including pain, inflammation, fever, cough, arthritis, skin diseases, and liver infections. This study sought to confirm the efficacy of Zingiber roseum (Roxb.) Roscoe leaves methanol extract (ZrlME) as reported in traditional usage by evaluating its analgesic, anti-inflammatory, and antipyretic capabilities. In addition, in silico molecular docking of the metabolites identified in ZrlME was studied to verify the experimental outcomes. ZrlME demonstrated strong dose-dependent analgesic efficacy against all analgesic tests. ZrlME (400 mg/kg) showed higher anti-inflammatory activity than the standard in the carrageenan-induced paw edema test model. A significant reduction of rectal temperature (3.97°F↓) was also recorded at the same dose of ZrLME after 24 h of treatment. Seven polyphenolic metabolites were identified and quantified by HPLC-DAD analysis, including 3, 4- dihydroxy benzoic acid, (-) epicatechin, rutin hydrate, p-coumaric acid, trans-ferulic acid, rosmarinic acid, and myricetin. Strong binding affinities (ranges from −5.8 to −8.5 Kcal/mol) between the aforesaid polyphenols and cyclooxygenase-2 were discovered. Moreover, molecular dynamics simulations (MDS) demonstrated that these polyphenols exhibit significant COX-2 inhibitory activity due to their high stability in the COX-2 active site. In computational prediction, the polyphenols were also found to be nontoxic, and a variety of biological activities, such as antioxidant, analgesic, anti-inflammatory, antipyretic, and hepatoprotective, were observed. The results of this study revealed that ZrlME possesses notable analgesic, anti-inflammatory, and antipyretic properties.

Background. Diabetes is a rising disorder that affects millions of people annually. It also creates more complications, such as neuropathy, oxidative stress, and hepatic and kidney impairment. Aphanamixis polystachya plant, which possesses multiple medicinal values, is used in this study to explore its potential in treating diabetes. Methods. A single dose (65 mg/kg) of intraperitoneal streptozotocin injection was utilized to mediate diabetes in Sprague-Dawley rats. Diabetic animals were treated orally with 250 or 500 mg/kg of standardized leaves’ extract of A. polystachya (AP) for 28 days to evaluate the antidiabetic and organ-protective effects of the plant. Different biochemical and histological markers are measured according to the established protocol. Results. Our results demonstrated a significant decrease in blood glucose (p <0.001) and HbA1c (p <0.05) levels in the diabetic animal after administering AP (250 and 500 mg/kg doses) compared to the control groups. AP can also regularize lipids, glycogen, alanine aminotransferase, and aspartate aminotransferase. Furthermore, serum urea nitrogen and creatinine decreased after treatment with AP in diabetic rats. AP also reduced oxidative stress markers and showed a substantial elevation in antioxidant enzymes in diabetic animals. Overall, AP at 500 mg/kg revealed comparable results against the standard antidiabetic drug glyburide. Besides, the histological investigation showed the AP’s efficacy in attenuating kidney tissue inflammation and damage. HPLC data elucidated that the AP leaf extract contains polyphenols with potential antioxidant, antidiabetic, and organ protective agents: gallic acid, rutin hydrate, and quercetin hydrate. Conclusion. Taken together, AP may be one of the potential sources of antidiabetic agents.

The analgesic and anthelmintic activities of the common fruits in the Sundarbans forest, Bangladesh were evaluated. Acetic acid-induced writhing test and hot plate test in mice model were demonstrated for examining the analgesic activity whereas an anthelmintic test was performed using a flatworm, Paramphistomum cervi of livestock ruminants. Among the fruits, Ceriops decandra showed the strongest analgesic activity through inhibiting acetic acid-induced writhing (45%) and increasing response time (16.8 sec) on a hot plate in mice at 250 mg extract/kg body weight (b.w.). Diclofenac sodium (25 mg/kg b.w.), a positive control, demonstrated writhing inhibition of 51.3% whereas morphine (10 mg/kg b.w.), a wellknown centrally active analgesic drug, increased response time of 18.2 sec. The fruits showed inhibition of acetic acid-induced writhing in mice with strong correlations to both the total polyphenols (r2 = 0.85) and the total flavonoids (r2 = 0.81) contents. Similar results were also observed for an increase of response time in mice on hot plate test. Therefore, both the peripheral and the central analgesic activities of the fruits were profoundly related to their total contents of polyphenols as well as flavonoids. Extract of Aegiceras corniculatum fruit displayed the strongest anthelmintic activity with the lowest CDT50 (concentration for death time 50) of 0.69 mg extract/ml whereas albendazole, a positive control, had CDT50 of 5.60 mg/ml for the parasite. The anthelmintic activity of the fruits was not dependent on their contents of polyphenols (r2 = 0.30) or flavonoids. The chromatograms of HPLC-DAD analysis detected caffeic acid, (+)-catechin hydrate, p-coumaric acid, (-)-epicatechin, rutin hydrate, and syringic acid in C. decandra fruit extract and quantified as 10.6, 598.4, 1.5, 28.5, 2 and 1.3 mg/100 g extract, respectively. Results revealed that C. decandra and A. corniculatum fruits are the potentials to treat pain and helminthiasis, respectively. Bangladesh J. Bot. 52(1): 79-86, 2023 (March)

AbstractThe use of vegetable tanning materials in leather processing has drawn attention as an alternative to basic chromium sulphate for its natural abundance and environmental aspects. In this work, an attempt has been made to extract vegetable tannins from Xylocarpus granatum bark using different solvents (e.g., water, methanol, ethanol, and chloroform) and compare with conventional vegetable tanning agents such as mimosa and quebracho. The highest extraction efficiency was observed 31.22% by methanol. The presence of tannin content and polyphenolic compounds, e.g. (-)epicatechin (503 mg/100 g dry extract), catechin hydrate (218 mg/100 g dry extract), catechol (29 mg/100 g dry extract) were ensured by UV–Vis, FT-IR spectroscopy and HPLC. Again, condensed tannins, moisture content, and pH of the methanol extracted tannin were found 47.80%, 5.82%, and 3.97 respectively. The leather tanned by Xylocarpus granatum tannin showed a shrinkage temperature of 86.34 ± 1.52 °C. Other properties such as tensile strength, tear strength, grain cracking load, and distention at grain cracking were comparable to conventional vegetable-tanned leather. The cross-sectional morphology of the tanned leathers was also characterized by scanning electron microscopy (SEM) which revealed a compact structure of the leather fibers. In light of the findings from the study, X. granatum bark tannin could be a well alternative to chromium and a new source of vegetable tannin for the leather industry. Graphical Abstract

Blumea lacera (Burm. f.) DC. is attracting scientific interest due to the diverse biological activities of its various parts and its use in folk medicine. The present study was undertaken to investigate the tissue‐specific differential expression pattern of its total bioactive compounds. The study was further extended to whole plant phenolics profiling, in vitro enzyme inhibition activities, followed by in silico enzyme inhibition analysis to assess its potential as herbal medicine. The amount of total phenolics in different tissues was followed in decreasing order as old leaf, flower bud, root, young leaf, flower, old stem, and young stem, while that for the flavonoids was old leaf, root, young leaf, flower bud, flower, young stem, and old stem. This study identified rosmarinic acid, quercetin, and kaempferol in this plant for the first time. The solvent extracts demonstrated strong inhibition of lipase and tyrosinase activity, along with varying degrees of inhibition of acetylcholinesterase and butyrylcholinesterase activity. Among the detected compounds, ten displayed strong in silico binding affinities with the tested enzymes. The findings provide a new insight into further investigation of the medicinal potential of this species against obesity, neurological disorders, and aberrant skin color.

ABSTRACT Ethanolic leaf extract of Tamarix indica was evaluated for the antioxidant and anticancer activities and toxicological profiles. The flavonoid, phenolic, and tannin contents of leaves were estimated as 5.3068 mg of QE g−1, 8.786 mg of GAE g−1, and 8.5216 mg of GAE g−1, respectively. In DPPH scavenging assay, T. indica leaves’ extract had an IC50 value of 74.38 μg mL−1. HPLC-DAD analysis identified catechin hydrate, vanillic acid, rutin hydrate, p-coumaric acid, and myricetin in different concentrations. In brine shrimp lethality bioassay, the IC50 value of the extract was 19.928 µg mL−1. Chemopreventive activity was evaluated using DMBA/croton oil-induced skin cancinogenic model mice. Oral treatment of the extract at different doses reduced the size, number, yield, and burden of tumor in skin carcinogenic mice. Natural antioxidants GSH and SOD increased with extract treatment. Additionally, reduction in blood bilirubin, SGPT, and SGOT levels were observed in extract treated mice. In acute toxicity study, no mortality was observed in mice justifying the safety of the extract.
