“…Phenolic content and antioxidant activities have been most frequently studied. In comparison with other largely consumed vegetables in the Mediterranean diet, Swiss chard displays high antioxidant activity [34]. In the current study, diabetic rats weighed less than non-diabetic rats, this is consistent with some previously published reports [35].…”

“…Experiments performed by Yanardag et al [43] demonstrated the hypoglycemic effect of Beta vulgaris var cicla extract in diabetic rats. This hypothesis was substantiated by further studies of the same group, who demonstrated a 40% reduction of glycaemia, without any loss of weight or impairment of liver functions [34,44]. The mechanism for the hypoglycemic action of the extract has been tentatively attributed to saponins that inhibit gluconeogenesis and glycogenolysis [45].…”

“…Some Cglycosylflavones, i.e. vitexin, vitexin-2-O-glycoside and VOR contained in Beta vulgaris leaves and seeds, were found to be strongly inhibit α-glucosidase and could be the most probable cause of the hypoglycemic effect [34]. In general, the reduced antioxidant capability in diabetes was the result of increased production of oxygen metabolites, which curbs the activity of the antioxidant defense system [49].…”

Objective: Oxidative stress which comes from hyperglycemia, it accelerates the development of cellular and vascular damage complications in diabetes, but the antioxidants may play a beneficial role in its prevention. Several plants extracts have an antioxidant activity and the ability to reduce oxidative stress in diabetes. Thus this study was conducted to investigate the effect of Beta vulgaris var cicla extract on zinc status, glucose concentration and antioxidant parameters in streptozotocin-diabetic rats fed zinc deficiency diet.Methods: Twenty-eight male albino (Wistar) rats were divided into four groups:Results: Body weight gain of zinc-deficient diabetic animals was lower than that of zinc-adequate diabetic animals. It was noticed also that inadequate dietary zinc intake increased glucose and MDA levels. In addition, zinc deficiency diet led to a decrease in zinc tissues, GSH concentration both GST and GSH-Px activities. However, Oral administration of Beta vulgaris extract significantly decreased both serum glucose and MDA (p<0.001) levels, with a significant increase in body weight gain (p<0.001), GSH concentration (p<0.05, P<0.001), GST (p<0.05, p<0.001) and GSHPx (p<0.001) activities.two groups fed a zinc-sufficient diet one non-diabetic and the other diabetic, while the others two diabetic groups were fed a zinc-deficient diet, one non-treated group and the other treated with the extract of Beta vulgaris var cicla. After 21 d of dietary manipulation, fasting animals were scarified. Blood glucose, tissues zinc (femur, liver, kidney), malondialdehyde (MDA), reduced glutathione (GSH), glutathione peroxidase (GSH-Px) and glutathione-S-transferase (GST) were evaluated. Conclusion:The present study showed that Beta vulgaris var cicla supplementation presumably acting as an antioxidant, and it can be a natural Keywords: Diabetes, Rat, Zinc deficiency, Beta vulgaris var cicla, Antioxidant source for the reduction of diabetes development caused by zinc deficiency.

The aim of this study was to examine the effects of chard on valproic acid (VPA)-induced cardiac damage. Female Sprague-Dawley rats were grouped as control, chard given control (100 mg/kg/day, by gavage), VPA (500 mg/kg/day, intraperitoneally) and chard given VPA (100 mg/kg/day chard by gavage, 500 mg/kg/day VPA, intraperitoneally). The aqueous extracts of chard leaves were given 1 h prior to administration of VPA for 7 days. Malondialdehyde (MDA), total sialic acid (SA) levels and catalase (CAT) activity significantly increased in the VPA group compared with the control group (P < 0.05). Chard administration significantly decreased MDA and SA levels in the control and in the VPA groups (P < 0.05). Chard administration also significantly increased CAT activities and glutathione levels both in the control and in the VPA groups (P < 0.05). As a conclusion, chard consumption may prevent cardiac tissue from oxidative stress and inflammation in VPA-induced toxicity.

“…(Mishra et al, 2010). The role of free radicals and other 'reactive oxygen/nitrogen/chlorine species' is widely recognized in the development of the diseases mentioned above (Topalović et al, 2013;Trifunović et al, 2015). Many studies have focused on the biological activities of phenolics, which are potent antioxidants and free-radical scavengers.…”

Swiss chard (Beta vulgaris L. var. cicla) is a leafy vegetable highly consumed in many parts of the world as a very popular ingredient of different diets. The purpose of this study was to evaluate effects of soil properties and fertilization on yield, mineral composition, total phenolics, antioxidant and biological activity of Swiss chard. The mineral composition of Swiss chard was generally affected by soil properties. The fertilization at 50% of recommended level (110 kg ha -1 N, 90 kg ha -1 P 2 O 5 and 100 kg ha -1 K 2 O per season) affected negatively yield and on the other hand affected positively antioxidant activity, while fertilization at 150% of recommended level had a contrary effect. The available K in soil affected the yield positively. Total phenolics were in negative correlation with the yield. The positive relationship of total phenolics and content of Mn in chard was noticed. The greatest efficacy in human colorectal carcinoma cell lines was obtained by Swiss chard extract from plants fertilized at 150% of recommended level.
