Abstract Objectives Neera, non-fermented coconut inflorescence sap (NFCIS) and its fermented form, toddy (FCIS) are the two well-known traditional drinks in South India. Both the saps show high rejuvenation effect and NFCIS is used for the curing of bronchial suffocation, anemia, tuberculosis and piles in traditional medicine. But, a few scientific studies have been reported on their health benefits so far. Presently, the antioxidant effect of both non-fermented (NFCIS) and fermented form (FCIS) of coconut inflorescence were analyzed in experimental animals. Methods The free radical scavenging property of FCIS and NFCIS was analyzed in vitro. The effect of these saps on mitigating sodium fluoride (NaF) deteriorated redox status was evaluated in mice. Results NFCIS exhibited high antioxidant activity than its fermented form. NFCIS reduces metal ions and scavenge hydroxyl and DPPH radicals with IC50 values 6.5 ± 1.9 and 44 ± 3.14 µL/mL, respectively. Supplementation of NFCIS for 14 days increased SOD, CAT and GPx activities and GSH level in liver by 51.67, 52, 27.88 and 35.77%, respectively against NaF induced decline with a concomitant decrease in lipid peroxidation to 40.76%. Saps rich in minerals indicate pharmaceutical and nutritional value. Conclusion The study revealed the antioxidant efficacy of non-alcoholic natural drink, Neera and recommends an alternative for synthetic carbonated soft drinks. The regular consumption of Neera may protect the body from various chronic diseases especially where the oxidative stress played as a key role.

The mechanisms that cause nickel (Ni) toxicity are multiple and potentially affect all cells in the body. For this purpose, we were interested in the oxidative stress induced by the Ni at the erythrocyte level at a dose of 2 g/l during the gestation and lactation period in the Wistar rats and the capacity of the clove essential oil, Syzygium aromaticum, (CEO) to restore or not this state of stress. Extraction of the CEO by hydro-distillation allowed us to obtain a CEO with a yield of 10.60% and the characterization of this essential oil by GC-MS indicates that the major components of this oil are: Eugenol (80.95%), eugenyl acetate (10.48%), β-caryophyllene (7.21%) and α-humulene (0.87%). The antioxidant activity of the CEO made in vitro showed a free radical scavenging capacity DPPH with an IC 50 of the order of 25.60 μg/ml. In addition, analysis of the erythrocyte antioxidant status indicated that Ni significantly increased the enzymatic activities of catalase (CAT) and superoxide dismutase (SOD) and significantly decreased the enzymatic activity of glutathione peroxidase (GPx), resulting in dysfunction of the antioxidant defense system. On the other hand, the administration of CEO by intraperitoneal (IP) over a period of 21 days to rats previously intoxicated with Ni, indicates that this CEO contributes significantly in improving defenses against free radical aggression, through a recovery. At the level of antioxidant enzyme activities by increasing their abilities to eliminate radical compounds.

In this study, the antioxidants and photosynthetic compounds of Verdolaga were examined. Compounds were extracted from distinctive segments of the verdolaga using various solvents such as methanol (40, 60, 80%), ethanol (40, 60, 80%), acetone (40, 60, 80%), and deionized water. The use of 80% methanol led to the highest extracted concentration of phenolic substances and flavonoids. The extracted products (Leaves, Stem strips, and Root strips) were evaluated for their radical scavenging capabilities with DPPH (IC50= 22.26, 20.56, and 32.10), and ABTS (IC50= 2.86, 3.70, and 5.24), reducing power (EC50= 15.70, 16.39, and 21.69), and peroxide scavenging activity (1C50= 1.717, 2.937, and 3.255), respectively. The extracted products were analyzed by a gas chromatography-mass spectrometer. Peroxidase, catalase, and polyphenol oxidase assays were completed for the crude extract of verdolaga’s leave, stem strips, and root strips. As indicated by these tests, extracts of the verdolaga’s roots, stems and leaves using 80% methanol yielded high antioxidant activity. The most elevated concentrations of extracted chlorophyll, lycopene, and carotenoids were from the leaves and the highest concentration of extracted tannin was noted from strips of stems. The highest measures of peroxidase and polyphenol oxidase were identified in root strips and the highest units of catalase was identified in leaves.

This study evaluated the antioxidant and anti-inflammatory properties of Marantochloa leucantha (Marantaceae). The in vitro antioxidant activity of the extracts and solvent fractions was evaluated by 1,1-diphenyl- 2-picrylhydrazyl (DPPH) radical scavenging and ferric reducing antioxidant potential (FRAP) assay models and in vivo anti-inflammatory activity by the rat paw edema model. The phytochemical screening indicated the presence of tannins, terpenoids, steroids, flavonoids, reducing sugar and phenolics. The antioxidant assay showed that all the extracts exhibited high antioxidant activity comparable with ascorbic and gallic acid controls. In DPPH model, a 250 μg/ml EtOAc fraction of the leaves showed antioxidant activity of 93.9 ± 1.7 % (EC50 0.82 μg/ml) and a 1000 μg/ml of same stem fraction produced 91.9 ± 0.3 % activity (EC50 1.38 μg/ml). In the FRAP model, EtOAc fraction exhibited 31.1±0.7 and 92.0 ± 2.2 μM Fe2+/g of dried leaves and stem, respectively at 1000 μg/ml FeSO4 equivalent. The anti-inflammatory potential of the plant showed that the crude stem extract and fractions at 200 - 600 mg/kg exhibited significant (p < 0.01) dose-related inhibition of paw edema in rats. A 200 mg/kg EtOAc fraction showed 18.8 % inhibition compared to 31 % observed in diclofenac-treated rats in 2 h post albumin challenge. These findings validated the folkloric use of this plant in the treatment of diseases associated to the oxidative stress and could further provide promising lead compounds with potent antioxidant and anti-inflammatory activities Dhaka Univ.

Fluoride is an important mineral for hard tissues in the body and appropriate fluoride exposure and usage are beneficial to bone and tooth integrity. Fluoride increases both bone density and bone mass due to stimulation of bone formation and it is used as a treatment for osteoporosis. Bioactive glasses have the capacity to form an intimate bond with living bone tissue due to formation of a mixed hydroxycarbonate apatite layer (HCA) in vitro and in vivo. This makes fluoride-containing bioactive glasses attractive biomaterials. In order to design fluoride-containing bioactive glasses, we need to understand the role of fluorine within the glass structure. A series of bioactive glasses with increasing fluoride content was prepared by a melt-quench route. Characterisation included differential scanning calorimetry (DSC), density measurements, MASNMR spectroscopy and studies in simulated body fluid (SBF). DSC results showed a linear decrease in glass transition temperature (Tg) with increasing amounts of fluoride. Density of the glasses increased with increasing amounts of fluoride. This may indicate an expansion of the silicate glass network accompanying incorporation of CaF2. 19F MAS-NMR spectroscopy showed broad peaks at chemical shifts between -135 and -120 ppm. As sodium fluoride gives a chemical shift of -223 ppm and calcium fluoride of -108 ppm, this indicated possible formation of mixed calcium sodium fluoride species. HCA and calcium phosphate layers were found on the glasses after one week of immersion in SBF showing the bioactivity of the glass series.

The present study is focused on the assessment of the medicinal therapeutic potential extracts of H. rosea to investigate their pharmacological implications based upon science proofs. The antioxidant activity of fraction of H. rosea, namely, n-hexane (HR-1), ethyl acetate (HR-2), chloroform (HR-3), and n-butanol (HR-4), was performed by using the DPPH radical scavenging method. The cytotoxicity and enzyme inhibition assessment were also performed. All the extracts showed significant antioxidant, antibacterial, and protein kinase inhibition but none of the extracts exhibited α-amylase inhibition activity. The chloroform extract HR-3 may block a kinase receptor from binding to ATP; the lead molecule will be isolated, which may stop cancerous cell growth and demotion of cell division. It is predicted that ethyl acetate, chloroform, and n-butanol extracts of H. rosea contain polyphenolics, flavonoids, and alkaloids that are biologically effective candidates exhibiting significant cytotoxicity, antioxidant, and antimicrobial activities. They may control oxidative damage in the body tissues and act as potential antidiabetic and anticancer agents. These studies will also be helpful for future drug designing and drug development research.

Dietary Plants

Natural products from dietary components such as Indian species and medicinal plants are known to possess antioxidant activity. Antioxidants are inhibitors of oxidation are compounds which prevent the oxidation and in general prolong the life of the oxidizable matter. Majority of the diseases/disorders are mainly linked to oxidative stress due to free radicals. The free radicals (oxidants) are species with very short half-life, high reactivity and damaging activity towards macromolecules like proteins, DNA and lipids. In general, the reactive oxygen species circulating and react with the electron of other molecules in the body and these also affect various enzyme systems and cause damage which may further contribute to conditions such as cancer, ischemia, ageing, adult respiratory distress syndromes, rheumatoid arthritis etc. Dietary plants contain variable amounts of antioxidants. It has been proved that plant antioxidants may contribute to the beneficial health effects of dietary plants. The present study was to evaluate antioxidant activity of ethanolic extract of iv vivo whole plant and in vitro leaf callus of Mollugo oppositifolia L. is an important traditional medicinal herb belonging to the family Molluginaceae using 2,2-diphenyl-1-Picrylhydrazyl (DPPH) radical scavenging assays. The results obtained showed that the ethanolic extracts of whole plant in vivo and in vitro leaf callus showed significant DPPH activity with IC50 value of 52.82± 0.0017 μg/mL and 58.66±0.004μg/mL respectively, while IC50 of vitamin C as standard was 84.84±11.54μg/mL.
