Objective. The aim of study was to determine the in vivo antioxidant activity of newly formulated O/W cream of methanolic extract of Cassia tora L. leaves. Methods. Oil in water (O/W) creams (0.05%, 0.1%, and 0.2%), cream base, methanolic extract of C. tora L. leaves (CTM), and standard (0.05% tretinoin cream) were screened for in vivo antioxidant activity. The ultraviolet- (UV-) B-induced rats were treated with different standard, O/W creams, cream base, and methanolic extract of Cassia tora L. leaves (CTM). The parameters like lipid peroxidation (LPO), reduced glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) levels were assessed. Results. The result of acute dermal toxicity shows that the creams were safe up to 2000 mg/kg (topically). Exposure of ultraviolet light of medium wave (UV-B light) decreased the level of GSH, CAT, and SOD and increased the LPO level. Concluding Remarks. We conclude that topical O/W creams of C. tora L. prevent the oxidative stress induced in rats by exposure to UV-B light by virtue of its in vivo antioxidant property, and these findings help to understand the mechanism of the antipsoriatic activity of O/W creams of C. tora L. in UV-B-induced psoriasis in the rat.

Abstract. Miftahudin, Hasibuan RS, Chikmawati T. 2019. Antioxidant activity of ethanolic extract of three Selaginella species from Java Island, Indonesia. Biodiversitas 20: 3715-3722. Three Selaginella species, S. ornata, S. plana, and S. willdenowii, from Java Island, Indonesia, have been known to have antioxidant properties; however, in vivo antioxidant activities of these species have not been reported. This research aimed to evaluate the in vivo antioxidant activity of ethanolic extract of three Selaginella species. The 70% ethanol extract of three Selaginella species at four different doses was administered to mice one day before being treated with oxidative stress. The liver tissue of mice treated with or without oxidative stress was analyzed their lipid peroxidation by measuring MDA concentration and Superoxide Dismutase (SOD) activities. The results showed that there were variations in antioxidant activity among the three Selaginella species. In general, the dose of 0.3 g extract kg-1 BW has been able to reduce lipid peroxidation and increase SOD activity. The administration of S. ornata extract to the mice at 1.2 g extract kg-1 BW reduced the MDA concentration to the lowest level, but the same dose of two other Selaginella extracts caused toxic effects in mice. The antioxidant activities of S. ornata and S. plana were better than that of S. willdenowii extract, and among those species, S. ornata has the best antioxidant activity.

Background: Garcinielliptone FC corresponds to a polyprenylated acylphloroglucinol having a benzophenonic core (diphenylmethanone) substituted with isoprenyl(s) group(s) (3-methyl-2-butenyl) and 2-isopropenyl-hex-5-enyl. Objective: The present work evaluated the antioxidant activity of garcinielliptone FC (GFC) in vitro against non-biological radicals [2,2-diphenyl-1-picrylhydrazyl (DPPH•) and 2,2'-azinobis-3- ethylbenzothiazoline-6-sulfonic acid (ABTS•+)] and ex vivo against oxidative damage induced by AAPH (2,2'-azobis-2-methylpropionamidine dihydrochloride) and iron/citrate ion in erythrocytes and mitochondria, respectively. Methods: In addition to the protective effect, the main biochemical indexes of oxidative stress, such as lipid peroxidation through the formation of Thiobarbituric Acid Reactive Substances (TBARS), Superoxide Dismutase (SOD), Catalase (CAT) activity and reduced glutathione (GSH) levels. Results: According to the results obtained in erythrocytes, the antioxidant results at concentrations of 0.1, 0.3, 0.7, 1.5 and 3.0 mM were 26.34 ± 0.68, 43.39 ± 2.17, 62.27 ± 2.17, 86.69 ± 0.47 and 92.89 ± 0.45%, respectively, where GFC reduced the rate of oxidative hemolysis when compared to AAPH (p<0.05). The antioxidant activity observed in erythrocytes was also seen in mitochondria in which GFC reduced mitochondrial swelling by increasing the absorbance when compared to iron/citrate ion complex (p<0.05). In both biological models, GFC had an antioxidant effect on erythrocyte and mitochondrial redox balance when analyzing oxidative stress biomarkers, such as reduction of lipid peroxidation and inhibition of depletion in the activity of SOD, CAT and GSH levels. Conclusion: In conclusion, GFC had in vitro and ex vivo antioxidant activity against oxidative damage induced in erythrocytes and mitochondria acting on the erythrocytic and mitochondrial redox balance.

Objective: Tocotrienol (TT), a constituent of vitamin E, present only in selected seed oil. Because of the isoprenoid side chain, antioxidant property of tocotrienol is recently highlighted. Application of tocotrienol is also proven to be neuroprotective. The current study was aimed to evaluate the effect of tocotrienol pretreatment on the serum and brain oxidative stress parameters and oxidant handling capacities.Methods: Male albino Wistar rats were treated with tocotrienol (10 mg/day) for two weeks and maintained for the next four weeks. Levels of reduced glutathione and lipid peroxidation and activities of superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase were estimated fortnightly in serum. After sacrifice, oxidative stress parameters were measured in the frontal cortex, temporal cortex, thalamic area, hippocampus and cerebellum. Glutathione-dependent and glutathione-independent superoxide and peroxide handling capacities (SPHC) were calculated for serum and brain regions. Data collected from both the groups are statistically processed with Kruskal-Wallis test and Mann-Whitney pairwise comparisons.Results: Significant impacts of TT treatment have been observed in terms of growth and water intake. Serum SPHC (Glutathione-independent) has been found to be reduced significantly immediately after the TT treatment. Region-specific alterations in oxidative stress parameters have also been observed after 4 w of supplementation. Global reductions in reduced glutathione and lipid peroxidation have been observed in the brain without any alteration in the SPHC.Conclusion: From the results, it can be suggested that the tocotrienol pretreatment possibly be used as neuroprotective measure particularly against oxidative stress. In addition, the antioxidant impacts of TT were found to be maintained for a longer period in brain regions, even though it was not so in the case of serum.

Oxidative stress and inflammation are interlinked processes. The aim of the study was to perform a phytochemical analysis and to evaluate the antioxidant and anti-inflammatory activities of ethanolic Mahonia aquifolium flower (MF), green fruit (MGF), and ripe fruit (MRF) extracts. Plant extract chemical composition was evaluated by HLPC. A DPPH test was used for the in vitro antioxidant activity. The in vivo antioxidant effects and the anti-inflammatory potential were tested on a rat turpentine oil-induced inflammation, by measuring serum nitric oxide (NOx) and TNF-alpha, total oxidative status (TOS), total antioxidant reactivity (TAR), oxidative stress index (OSI), 3-nitrothyrosine (3NT), malondialdehyde (MDA), and total thiols (SH). Extracts were administrated orally in three dilutions (100%, 50%, and 25%) for seven days prior to inflammation. The effects were compared to diclofenac. The HPLC polyphenol and alkaloid analysis revealed chlorogenic acid as the most abundant compound. All extracts had a good in vitro antioxidant activity, decreased NOx, TOS, and 3NT, and increased SH. TNF-alpha was reduced, and TAR increased only by MF and MGF. MDA was not influenced. Our findings suggest that M. aquifolium has anti-inflammatory and antioxidant effects that support the use in primary prevention of the inflammatory processes.

Water-pipe smoking (WPS) is a common practice in the Middle East and is now gaining popularity in Europe and the United States. However, there is a limited number of studies on the respiratory effects of WPS. More specifically, the underlying pulmonary pathophysiological mechanisms related to WPS exposure are not understood. Presently, we assessed the respiratory effects of nose-only exposure to mainstream WPS generated by commercially available honey flavored “moasel ” tobacco. The duration of the session was 30 min/day and 5 days/wk for 1 mo. Control mice were exposed to air only. Here, we measured in BALB/c mice the airway resistance using forced-oscillation technique. Lung inflammation was assessed histopathologically and by biochemical analysis of bronchoalveolar lavage (BAL) fluid, and oxidative stress was evaluated biochemically by measuring lipid peroxidation, reduced glutathione and several antioxidant enzymes. Pulmonary inflammation assessment showed an increase in neutrophil and lymphocyte numbers. Likewise, airway resistance was significantly increased in the WPS group compared with controls. Tumor necrosis factor α and interleukin 6 concentrations were significantly increased in BAL fluid. Lipid peroxidation in lung tissue was significantly increased whereas the level and activity of antioxidants including reduced glutathione, glutathione S transferase, and superoxide dismutase were all significantly decreased following WPS exposure, indicating the occurrence of oxidative stress. Moreover, carboxyhemoglobin levels were significantly increased in the WPS group. We conclude that 1-mo nose-only exposure to WPS significantly increased airway resistance, inflammation, and oxidative stress. Our results provide a mechanistic explanation for the limited clinical studies that reported the detrimental respiratory effects of WPS.

Sickle cell disease promotes hemolytic anemia and occlusion of small blood vessels due to the presence of high concentrations of hemoglobin S, resulting in increased production of reactive oxygen species and decreased antioxidant defense capacity. The aim of this study was to evaluate the protective action of a standardized extract of Ginkgo biloba (EGb 761), selected due to its high content of flavonoids and terpenoids, in erythrocytes of patients with sickle cell anemia (HbSS, SS erythrocytes) subjected to oxidative stress using tert-butylhydroperoxide or 2,2-azobis-(amidinepropane)-dihydrochloride, in vitro. Hemolysis indexes, reduced glutathione, methemoglobin concentrations, lipid peroxidation, and intracellular reactive oxygen species were determined. SS erythrocytes displayed increased rates of oxidation of hemoglobin and membrane lipid peroxidation compared to normal erythrocytes (HbAA, AA erythrocytes), and the concentration of EGb 761 necessary to achieve the same antioxidant effect in SS erythrocytes was at least two times higher than in normal ones, inhibiting the formation of intracellular reactive oxygen species (IC50 of 13.6 µg/mL), partially preventing lipid peroxidation (IC50 of 242.5 µg/mL) and preventing hemolysis (IC50 of 10.5 µg/mL). Thus, EGb 761 has a beneficial effect on the oxidative status of SS erythrocytes. Moreover, EGb 761 failed to prevent oxidation of hemoglobin and reduced glutathione at the concentrations examined.

The effects of C60FAS (50 and 500 μg/kg) supplementation, in a normal physiological state and after restraint stress exposure, on prooxidant/antioxidant balance in rat tissues were explored and compared with the effects of the known exogenous antioxidant N-acetylcysteine. Oxidative stress biomarkers (ROS, O2⋅−, H2O2, and lipid peroxidation) and indices of antioxidant status (MnSOD, catalase, GPx, GST, γ-GCL, GR activities, and GSH level) were measured in the brain and the heart. In addition, protein expression of Nrf2 in the nuclear and cytosol fractions as well as the protein level of antiradical enzyme MnSOD and GSH-related enzymes γ-GCLC, GPx, and GSTP as downstream targets of Nrf2 was evaluated by western blot analysis. Under a stress condition, C60FAS attenuates ROS generation and O2⋅− and H2O2 releases and thus decreases lipid peroxidation as well as increases rat tissue antioxidant capacity. We have shown that C60FAS supplementation has dose-dependent and tissue-specific effects. C60FAS strengthened the antiradical defense through the upregulation of MnSOD in brain cells and maintained MnSOD protein content at the control level in the myocardium. Moreover, C60FAS enhanced the GSH level and the activity/protein expression of GSH-related enzymes. Correlation of these changes with Nrf2 protein content suggests that under stress exposure, along with other mechanisms, the Nrf2/ARE-antioxidant pathway may be involved in regulation of glutathione homeostasis. In our study, in an in vivo model, when C60FAS (50 and 500 μg/kg) was applied alone, no significant changes in Nrf2 protein expression as well as in activity/protein levels of MnSOD and GSH-related enzymes in both tissues types were observed. All these facts allow us to assume that in the in vivo model, C60FAS affects on the brain and heart endogenous antioxidative statuses only during the oxidative stress condition.
