Background : Nowadays with the appearance of diseases such as cancer, atherosclerosis, free radicals are often singled out. What motivates scientific research in natural antioxidants. Aim/Objective : The aim of this study was to determine the antioxidant activity of the stalks and the fruit of Solanum melongena L. Study Duration : The period of the study was done on 25th July, 2015 at the Department of Pharmacy, Faculty of Medecine, Pharmacy and Odontology, University of Dakar, Senegal. Methodology : Antioxidant activity was evaluated through two methods (DPPH and FRAP). Results : For the FRAP test, at the highest concentration (83.3 µg/ml) the aqueous extract of the fruit (0.90±0.08) has a higher reducing power compared to those of ethanol extracts from the fruit (0.77±0.41) and the stalk (0.85±0.004). These results remain inferior to that of tannic acid (0.95± 0.0005). The DPPH test reveals that the ethanolic extract of the fruit is more effective in reducing the free radical DPPH with an inhibitory concentration 50 (IC 50) equal to 3.37±0.03 μg / ml, followed by the ethanolic extract of the stalks (IC 50 = 4.46±0.24 μg / ml) and finally the aqueous extract of the fruit (IC50 = 9.6±0.026 μg / ml). Conclusion : These results make it possible to confirm the in vitro activity of the parts studied, but in vivo studies are necessary in order to know the acute and chronic toxicities. Finally, perform a bio-guided fractionation to determine the molecules responsible for the antioxidant activity.

Moringa oleifera Lam. is a highly valued medicinal plant in India, especially Kerala. In the present study, antioxidant activity of aqueous extract of leaves of M. oleifera was determined both in-vitro and in-vivo. Male Wistar rats of 3 age groups- 6, 12, and 18 months old were used for in-vivo analysis. In vitro anti-proliferative effect of the extract was carried out in Dalton’s Lymphoma Ascites (DLA) Cells. LCMS-QTOF analysis of the extract was also done to determine the bioactive components present in the extract. Antioxidant activity of M. oleifera leaf showed an IC 50 value of 10.47 ?g/ml and whereas for standard drug, ascorbic acid, it was 19.52 ?g/ml. In-vivo analysis of lipid peroxidation showed a significant reduction of lipid peroxidation in the brains of 12 and 18-months old treated groups. Up to 75% mortality of DLA cancerous cells was observed in-vitro in different concentrations of M. oleifera leaf water extract in a dose-dependent manner, demonstrating its anti-proliferative property. LCMS-QTOF analysis revealed the presence of emodin-8-glucoside in the extract. Molecular docking analysis (Auto Dock Vina) of emodin-8-glucoside with six cancer related proteins showed highest binding affinity with AKT-1 with a binding score of -10.4 kcal/mol, also showed good affinity with NF-kB (p65), Stat-3, Bcl-2, Bcl-xl and c-FLIP. This study helps to choose healthy diet practices to overcome free radical onslaught and cancerous cell proliferation especially in the later stages of life. This can also pave way for the emergence of diet based therapeutic cure for cancer.

In this study a polyphenolic extract from Cleome arabica leaves (CALE) was investigated for its antioxidant activity in vitro using DPPH•, metal chelating and reducing power methods and for its protective effects against AraC-induced hematological toxicity in vivo using Balb C mice. Results indicated that CALE exhibited a strong and dose-dependent scavenging activity against the DPPH• free radical (IC50 = 4.88 μg/ml) and a high reducing power activity (EC50 = 4.85 μg/ml). Furthermore, it showed a good chelating effects against ferrous ions (IC50 = 377.75 μg/ml). The analysis of blood showed that subcutaneous injection of AraC (50 mg/kg) to mice during three consecutive days caused a significant myelosupression (P < 0.05). The combination of CALE and AraC protected blood cells from a veritable toxicity. Where, the number of the red cells, the amount of hemoglobin and the percentage of the hematocrite were significantly high. On the other hand, AraC cause an elevation of body temperature (39 °C) in mice. However, the temperature of the group treated with CALE and AraC remained normal and did not exceed 37.5 °C. The observed biological effects of CALE, in vitro as well as in vivo, could be due to the high polyphenol and flavonoid contents. In addition, the antioxidant activity of CALE suggested to be responsible for its hematoprotective effect.

This systematic review aims to elucidate the role of melatonin (N-acetyl-5-metoxy-tryptamine) (MLT) in the prevention and treatment of cancer. MLT is a pineal gland secretory product, an evolutionarily highly conserved molecule; it is also an antioxidant and an impressive protector of mitochondrial bioenergetic activity. MLT is characterized by an ample range of activities, modulating the physiology and molecular biology of the cell. Its physiological functions relate principally to the interaction of G Protein-Coupled MT1 and MT2 trans-membrane receptors (GPCRs), a family of guanidine triphosphate binding proteins. MLT has been demonstrated to suppress the growth of various tumours both, in vivo and in vitro. In this review, we analyze in depth, the antioxidant activity of melatonin, aiming to illustrate the cancer treatment potential of the molecule, by limiting or reversing the changes occurring during cancer development and growth.

Background: Diabetes mellitus is major issue to public health as its prevalence is rising day by day. Synthetic agents available for the diabetic treatment are expensive or produce undesirable side effect on chronic use and some of them are not suitable during pregnancy. Herbal medicines accepted widely due to side effects and low cost. Objective: The aim of present study was to evaluate the activity of Withania coagulans extract using In-vitro and In-vivo model. Methods: Different three types of Withania coagulans extract were prepared using aqueous (W1), Alcohol (W2) and hydro-alcoholic (50:50) mixture (W3). In-vitro Anti-diabetic activity of the all three extracts evaluated using RINm5F Pancreatic beta cells.Further, n-vivo anti-diabetic evaluation performed by administering 50 mg/kg (p.o) aqueous extract for 7 days in Streptozotocin (STZ)-induced mice. Body weight of the animals was also determined to perform acute toxicity study. Results: The results of in –vitro cell based study indicated that among all three extract, aqueous extract (W1) of Withania coagulans showed potential increase in inulin release. The EC50 of the W1 (249.6 µg/L) which is compared with standard (Glibenclamide) EC50. From the results of In-vitro study, W1 subjected for acute toxicity study and the acute toxicity study results indicated LD50 of 50mg/kg. Diabetic rats treated with W1 extract at oral dose of 50 mg/kg for 7 days showed 34.17% reduction in blood glucose in comparison to untreated diabetic (STZ-induced) rats. Blood glucose levels of Standard treated (Glibenclamide) and control untreated. Conclusion: In conclusion, results of pancreatic beta cell based study showed increase in insulin release by administration of extract. Further aqueous extract (W1) was potentially reduced blood glucose level in STZ induced diabetic mice.
