Antioxidant Effects

Metabolic diseases have increased considerably such as diabetes mellitus (DM). Since diabetes is a systemic disease, it implies high cardiovascular risks. It has been widely established that cardiac injury is related to mitochondrial dysfunction through increment of reactive oxygen species (ROS). Synthetic antioxidants can have important side effects; therefore natural sources may represent a better option. Traditional Mexican medicine has been using Eryngium carlinae (EC) for medical treatment. Also our group showed that hexanic extract possesses in vitro antioxidant capacity. Experimental diabetes in Wistar rats was generated by streptozotocin (STZ) and hexanic extract of EC was supplied for 7 weeks (30 mg/kg). Cholesterol, triacylglycerides, glucose, and thiobarbituric acid reactive substances (TBARS) levels were determined in serum. Mitochondria from left ventricle were used in the quantification of TBARS, reduced glutathione, nitric oxide (NO) levels and activity of superoxide dismutase (SOD) enzyme was performed.  Biochemical parameters of glucose and triacylglycerides, as well as TBARS levels in serum show a significant reduction in diabetic group supplied with EC hexanic extract. Thus, we can conclude that the EC hexanic extract possesses antioxidant activity in vitro, and in vivo, by reducing glucose and triacylglycerides levels during hyperglycemia, which may eventually reduce the risk of developing diabetic cardiomyopathy.

Abstract. Diabetes mellitus (DM) is a globally growing health problem and one of the most prevalent endocrine disorders worldwide. Chronic hyperglycemia status favors the manifestation of oxidative stress by increasing the production of reactive oxygen species and/or by reducing the antioxidant defense system activity. In this study, the beneficial effects of apple cider vinegar (ACV) supplementation on blood glucose level, hepatic and renal toxicity and antioxidant enzyme activities in normal and diabetic rats were investigated. Four groups (8 animals/group) of male Wistar rats were used. The animals were fasted overnight and DM was induced by an intraperitoneal injection of freshly prepared streptozotocin (STZ). Control rats were injected with citrate buffer only. ACV was administrated orally for 4 weeks. Our findings indicated that ACV increased the activity of antioxidant enzymes (superoxide dismutase (p < 0.001), catalase and glutathione peroxidase) as well as thiol concentration (p < 0.05). It also reduced lipid peroxidation levels (TBARS) and the indices of toxicity in liver and kidneys, by significantly decreasing aspartate and lactate transaminase (AST & ALT) activity, total and direct bilirubin (p < 0.001), urea (p < 0.001) and creatinine (p < 0.001) levels. Moreover, the plasma concentration of magnesium, calcium (p < 0.001) and copper increased after ACV administration. Iron levels however decreased. The concentration of vitamin E, an important antioxidant in vivo, was raised. In conclusion, the findings show that ACV possesses significant antihyperglycemic and antioxidant effects in an experimental model of DM, by preventing diabetic complications in liver and kidneys.

Background: The leaves of Annona reticulata Linn. have been traditionally used by the tribes of Assam as a source of medicine to mitigate a range of health ailments including diabetes and obesity. Objectives: The current study aimed to evaluate the anti-diabetic and anti-hyperlipidemic potential of bioactive fractions isolated from the methanolic extract of Annona reticulata Linn. leaves using Nicotinamide + Streptozotocin (60 mg/kg, i.p.) induced diabetic rats. Methods: The partially purified bioactive fractions, namely F1, F2, F3 and F4 were administered to diabetic rats with the dose of 200 mg/kg, per oral (p.o.) and the effect of the fractions on serum glucose were studied up to 21 days. The potent fractions were further subjected for spectral analysis for identification of the isolated active compounds. Results: The in-vivo anti-diabetic activity of the isolated fractions F2 and F3 were found significant controlling blood glucose level, alike glibenclamide. Interestingly, F2 and F3 treated animals were found significant in restoring the lipid and liver enzymes profile in streptozotocin challenge rats. Further, spectral analysis revealed that F2 and F3 were comprises Quercetin and Gallic acid, respectively. Conclusion: Outcome of finding demonstrate the anti-diabetic and anti-hyperlipidemic potential of the isolates/fractions of A. reticulata, which were found enriched in polyphenolics including Quercetin and Gallic acid; and provides logistic behind the traditional use of the A. reticulata against Diabetes and obesity.

Conifers have long been recognized for their therapeutic potential in different disorders. Alkaloids, terpenes and polyphenols are the most abundant naturally occurring phytochemicals in these plants. Here, we provide an overview of the phytochemistry and related commercial products obtained from conifers. The pharmacological actions of different phytochemicals present in conifers against bacterial and fungal infections, cancer, diabetes and cardiovascular diseases are also reviewed. Data obtained from experimental and clinical studies performed to date clearly underline that such compounds exert promising antioxidant effects, being able to inhibit cell damage, cancer growth, inflammation and the onset of neurodegenerative diseases. Therefore, an attempt has been made with the intent to highlight the importance of conifer-derived extracts for pharmacological purposes, with the support of relevant in vitro and in vivo experimental data. In short, this review comprehends the information published to date related to conifers’ phytochemicals and illustrates their potential role as drugs.

Reactive oxygen and nitrogen species have been implicated in the onset and progression of various diseases and the role of antioxidants in the maintenance of health and prevention of diseases has received much attention. The action and effect of antioxidants have been studied extensively under different reaction conditions in multiple media. The antioxidant effects are determined by many factors. This review aims to discuss several important issues that should be considered for determination of experimental conditions and interpretation of experimental results in order to understand the beneficial effects and limit of antioxidants against detrimental oxidation of biological molecules. Emphasis was laid on cell culture experiments and effects of diversity of multiple oxidants on antioxidant efficacy.
