6 Hydroxydopamine

Ceratonia siliqua L. is a Mediterranean medicinal plant traditionally cultivated for its ethnopharmacological benefits, such as antidiarrheal, antidiabetic, enhance acetylcholine, antioxidant, antiatherosclerotic, and for its possible anti-neurodegenerative potential. The aim of the present study was to evaluate the chemical composition, as well as the cognitive-enhancing, anxiolytic, and antioxidant activities of the aqueous extract from C. siliqua (CsAE) leaves against 6-hydroxydopamine (6-OHDA) zebrafish Parkinson’s disease (PD) model. CsAE (0.1, 0.3, and 1 mg/L) was administered by immersion to zebrafish (Danio rerio) for eight consecutive days and one hour before each behavioral test of each day, while 6-OHDA (250 µM) treatment was supplied one day before the novel tank diving test (NTT). Qualitative and quantitative analyses were performed by the ultra-high-performance liquid chromatography (UHPLC) analysis. The memory performance was evaluated through the NTT and Y-maze tests. Additionally, the in vitro and in vivo antioxidant status and acetylcholinesterase (AChE) activity was also assessed. Our finds demonstrated that CsAE presented positive antioxidant and anti-AChE activities, which contributed to the improvement of cognitive function in the 6-OHDA zebrafish PD model.

Abstract An ultra-high-performance liquid chromatography-high-resolution mass spectrometry based profiling of a purified MeOH extract (PME) from the roots of Chenopodium bonus-henricus L. (Amaranthaceae) tentatively identified 15 saponins of six sapogenins. The PME exerts hepatoprotective and antioxidant activities comparable to those of flavonoid complex silymarin in in vitro (1 and 10 μg/mL) and in vivo (200 mg/kg/daily for 7 days) models of hepatotoxicity, induced by CCl4. The main constituents of PME, respectively saponins bonushenricoside A (1), 3-O-β-D-glucuronopyranosyl-bayogenin-28-O-β-D-glucopyranosyl ester (2), 3-O-β-D-glucuronopyranosyl-medicagenic acid-28-O-β-D-xylopyranosyl (1→4)-α-L-rhamnopyranosyl(1→2)-α-L-arabinopyranosyl ester (3), 3-O-β-D-glucuronopyranosyl-2β-hydroxygypsogenin-28-O-β-D-glucopyranosyl ester (4), 3-O-α-L-rabinopyranosyl-bayogenin-28-O-β-D-glucopyranosyl ester (6) and bonushenricoside B (8) (3 μg/mL each), compared to silymarin (5 and 50 μg/mL), significantly reduced the cellular damage caused by CCl4 in rat hepatocytes, preserved cell viability and glutathione level, decreased lactate dehydrogenase leakage and reduced lipid damage. The experimental data suggest that the glycosides of phytolaccagenin, bayogenin, medicagenic acid, 2β-hydroxygypsogenin, 2β-hydroxyoleanoic acid and oleanoic acid are a promising and safe class of hepatoprotective agents.

Background: Antioxidants are developed to assist the immune system and overcome oxidative stress, the aggression of cellular constituents due to imbalance between reactive oxygen species and the inner antioxidant system. The main objective of this study was to search for new and potent antioxidants to protect humans against diseases associated with oxidative stress. Methods: In this study, three pyrano-[2,3-c]-pyrazole derivatives were synthesized via Multicomponent Reaction (MCR) approach and were characterized, using a melting point, High-Performance Liquid Chromatography (HPLC), and spectroscopic analyses (IR; 1H-NMR; 13C-NMR). All of the generated compounds were screened for their antioxidant properties in vivo, using ciliate “Tetrahymena” as a model organism exposed to oxidative and nitrative stress. They were then studied in vitro by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) assays. Results: The results demonstrated that the three compounds (5a, b, c) are biologically active and possess potent antioxidant activities, especially the 5a and 5b derivatives. On the other hand, the in vitro bioassays revealed that the 5a derivative possessed a significant antioxidant activity much greater than ascorbic acid. Accordingly, the in silico data are consistent with the experimental data. Conclusion: These findings confirmed the potent antioxidant property of the synthesized compounds, providing us with new inspiration and challenges to design a library of pharmaceutical compounds with strong activity and low toxicity in the future.

Ceratonia Siliqua L

  The role of polyphenols and flavonoids in prevention of cellular damages carried out with the oxidative stress is well documented. In the present experiment, we determined the polyphenols and flavonoids concentrations of three extracts (ethanol 70%: V/V, methanol 80%: V/V and distilled water extracts) of carob pulp mature (Ceratonia siliqua L.) and their in vitro and in vivo antioxidant activity. A significant dose-dependent anti-free radical activ-ity of ethanolic extract of carob (EEC) was related to the highest polyphenol content (44.74 mg QE/mL) and to the in vitro antioxidant activity (EC50 = 0.28 mg/mL) of this extract. LC-MS /MS analysis of the EEC have shown the presence of several phenolic compounds as well as many types of flavonoids. The in vivo experiment brought out the significant effect of the daily EEC oral pre-treatment of rats, 30 min before AlCl3 administration for 28 d on the improvement of the total blood antioxidant capacity. These results suggest that the carob pulp contain many substances having in vitro and in vivo antioxidant effects, and which could be used as natural food additives in order to preserve food quality.

Cyclocarya paliurus has been widely used as an ingredient in functional foods in China. However, the antioxidant properties of phenolic compounds and the effect of the plant origin remain unclear. The present study evaluated the geographical variation of this plant in term of its phenolic composition and antioxidant activities based on leaf materials collected from five regions. high-performance liquid chromatography (HPLC) analysis showed that there are three major components, quercetin-3-O-glucuronide, kaempferol-3-O-glucuronide, and kaempferol-3-O-rhamnoside, and their contents varied significantly among sampling locations. The investigated phenolic compounds showed substantial antioxidant activities, both in vitro and in vivo, with the highest capacity observed from Wufeng and Jinzhongshan. Correlation analysis revealed that quercetin and kaempferol glycosides might be responsible for the antioxidant activities. Our results indicate the importance of geographic origin, with sunny hours and temperature as the main drivers affecting the accumulation of C. paliurus phenolics and their antioxidant properties.

Aging is one of the main risk factor for the onset of cardiovascular diseases; one of the possible explanations could be linked to the age-associated overproduction of free radicals. This increase of oxidative stress can be overcome with a high intake of food antioxidants. In this context, a number of studies have been addressed to assess the antiaging potential of natural antioxidant compounds. Recently, it has been shown that the juice of bergamot (Citrus bergamia Risso et Poiteau), a fruit mostly produced in the Ionian coastal areas of Southern Italy (Calabria), is a valuable source of health-promoting constituents with, among other, antioxidant properties. In order to investigate the potential antiaging effects of this Mediterranean natural antioxidant source, bergamot juices of three different cultivars (“fantastico,” “femminello,” and “castagnaro”) were herein characterized by the mean of high-performance liquid chromatography-photodiode array-electrospray ionization-tandem mass spectrometry. Then, juices were investigated for the evaluation of total polyphenolic and flavonoid contents, cell-free model antioxidant activities, and in vitro antiaging properties on two different cellular models of induced myocardial senescence. The best performing juice was also assessed in vivo. The phytochemical profiles confirmed that juices were rich in flavonoids, both flavone and flavanone glycosides. In addition, two limonoid glycosides were also identified in all cultivars. Each cultivar showed different phenolic and flavonoid contents. In tube results showed the juice robust antioxidant activities that correlate with their phenolic and flavonoid contents. Moreover, for the first time, the ability of juice to counteract the chemical-induced senescence was here demonstrated in both cellular models. Lastly, the in vivo data obtained from mouse hearts evidenced an increase in transcription of genes involved in antiaging and antioxidant responses. The overall results suggest that bergamot juice exerts antioxidant and antisenescence effects, making it useful for nutraceutical purposes.

Abstract Background: Ginseng Antler Yam Tang (GAYT), believe to invigorate “Qi” (vital energy), nourish “Blood” (body circulation) and engender “liquid” (body fluid), is a traditional Chinese medicine formula derived from the traditional prescription and Chinese traditional medicine partner theory. Methods: In this study, we aimed to evaluate the anti-fatigue effects of GAYT and its mechanisms are related to oxidative stress signaling using GAYT composition, in vitro and in vivo antioxidant, and biochemical index detection. Chemical components analysis of GAYT was performed by high performance liquid chromatography (HPLC) and ultraviolet spectrophotometry (UV). Results: The results show that the GAYT is rich in protein, total flavonoids, total polysaccharide and saponin. The mice model was treatment by GAYT (0.9, 1.8 and 3.6g/kg) for 4 weeks. GAYT treatment enhanced antioxidant activities. GAYT significantly enhances the exercise performance in weight-loaded swimming, rotating rod, and forced running test. Biochemical index levels showed that these effects were closely correlated with inhibiting the depletion of glycogen, blood lactic acid (LD) and adenosine triphosphate (ATP) stores, regulating oxidative stress-related parameters (superoxide dismutase (SOD), glutathione peroxidase (GSH-PX) and malonaldehyde (MDA)) in serum and liver of mice. Moreover, the results show that the effects of GAYT may be related with its regulation on the activations of AMP-activated protein kinase and protein kinase B in liver of mice.Conclusions: GAYT can induce recovery from fatigue in mice via the activation of the AMPK and AKT/mTOR pathways. Provide a theoretical basis for the study of GAYT's anti-fatigue effect
