Lamium amplexicaule L. is a genus of the family Lamiaceae. This plant species has been used widely in traditional medicines to treat many disorders. Phytochemical screening (qualitative and quantitative), antioxidant capacity, total phenol, and total flavonoid content were analyzed in a crude extract of leaves. The extract was prepared in aqua-methanol and aqua acetone in 30:70. Antioxidant capacity was analyzed in both extracts through (2,2-diphenyl-1picrylhydrazyl (DPPH) Free Radical Scavenging Assay, FRAP (Ferric Ion Reducing Antioxidant Potential), FCA (Fe2+ Ion Chelating Activity), Phosphomolybdenum assay (TAA), Total Phenol Content (TPC) and Total Flavonoid Content (TFC). Both extracts showed the presence of tannins, alkaloids, flavonoids, proteins, phenols, saponins, terpenoids, carbohydrates, quinones, oils, and resins. The result for antioxidant assay (DPPH, FRAP, FCA and TAA) was comparatively higher in aqua-methanol than in aqua-acetone. TFC values were higher in aqua-acetone, while TPC in aqua-methanol extract. Thus, the plant species can be used as a potent source of ayurvedic...

Background: The current study was conducted at the department of veterinary pharmacology and toxicology to assess the impact of Emblica officinalis on oxidative stress produced by sub-acute enrofloxacin exposure in albino rats. Methodology: Albino rats weighing 200-300 grams were given enrofloxacin and Emblica officinalis orally through gavage needle. Blood samples were taken via capillary tube on the 28th day of the experiment and analyzed using laboratory procedures. Result: Sub-acute treatment of enrofloxacin at doses of 5 mg/kg b.wt. and 10 mg/kg b.wt. generated oxidative stress in rats, as evidenced by substantial changes in oxidative parameters, and affected liver and kidney functions, as seen by changes in biochemical markers of liver and kidney function. Emblica officinalis aqueous extract (200 mg/kg b. wt.) effectively reduces oxidative stress and changes in hepatic and renal function caused by enrofloxacin. Conclusion: Emblica officinalis (Amla) has antioxidant properties and can reduce oxidative stress caused by enrofloxacin in albino rats following sub-acute...

Natural herbs have had to show profound action for many years. The phytochemicals present in plants responsible for preventing disease and promoting health have been studied extensively to establish their efficacy and understand their action’s underlying mechanism. Such studies have included identifying and isolating the chemical components and establishing their biological potency both by in-vitro and in-vivo studies in experimental animals and through epidemiological and clinical-case control studies in man. The present work describes “Isolation, Characterization and Biological Evaluation of Madhuca longifolia seeds”. The seeds were collected, authenticated, shade dried and powdered using a mechanical grinder. The powdered material was extracted by the Soxhletion method by using solvents in increasing order of polarity i.e, hexane, ethyl acetate and methanol. The percentage yield of hexane extract was found to be (57.8%), ethyl acetate extract (4.6%) and methanolic extract (18.9%) was respect to the powdered crude drug. Each extract was subjected to preliminary phytochemical screening using standard phytochemical methods. The hexane, ethyl acetate and methanol extracts were found to be rich...

Phytopharmacology is always a vital way for drug discovery. Antibiotic resistance is rising as a challenging threat day by day. Diarrhea and pain are always common problems. The present study was designed to evaluate the Analgesic, Antidiarrhoeal, and Antibacterial activities of ethanol extracts of leaf of Limnophila polystachya Benth by different methods. The analgesic activity of the samples was studied using the acetic acid-induced writhing model in mice. The Thomas method observed castor oil-induced antidiarrheal activity, and antimicrobial activity was monitored by the disc diffusion method. At a higher dose (500 mg/kg), Limnophila polystachya Benth inhibited 65.79 % and 63.16 % writhing of stem and leaf acetone extracts, respectively, compared to standard drug Diclofenac sodium inhibited 78.07 %writhing. Further study is needed to find possible active ingredients and mechanisms of action as well. At a higher dose (500 mg/kg) of the acetone stem and leaf extracts, significant inhibition of 50.58 and 52.87 % of characteristic diarrhoeal feces was observed, respectively, and at a lower dose (250 mg/kg) of both...

Cupressus macrocarpa (C. macrocarpa) is an evergreen tree with medicinal uses. The essential oil of C. macrocarpa possesses a powerful antimicrobial and antifungal effect against several bacteria and fungi. We aimed of this study to evaluate the antibacterial activity of C. macrocarpa. Fresh leaves of C. macrocarpa were collected and dried in the shade at room temperature. The essential oil was obtained using hydrodistillation, and yield was recorded. The antibacterial activity of the essential oil against Staphylococcus aureus, Pseudomonas aeruginosa and Proteus vulgaris was examined, and minimal inhibitory concentration (MIC) was determined using a microdilution assay. As a result, the yield of essential oil from dried and fresh leaves was 0.39% and 0.4%, respectively. The MIC was 0.01 (v/v) for both Staphylococcus aureus and Proteus vulgaris, where the essential oil exhibited lower activity against Pseudomonas aeruginosa with a MIC of 0.04 (v/v). These results show the importance of using Cupressus macrocarpa essential oil to treat infection of several known resistant...
