“…It has been suggested that the antioxidant and free radical-scavenging activities might be also due to the presence of terpenoids in chard. Pyo et al [59] showed a linear correlation between radical-scavenging effect and polyphenolic concentration of chard. Phenolic acids and flavonoids containing multiple hydroxyl groups have higher antioxidant activities against free radical species.…”

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.

“…However, BHA (IC 50 =12.1 μg/mL) and α-tocopherol (IC 50 =13.9 μg/mL) showed 90.64 and 92.83% radical scavenging activity at a concentration of 25 μg/mL, respectively. The free radical scavenging activities of pure antioxidant compounds, plant and fruit extracts and food materials (19,20) exhibit an almost linear correlation between DPPH radical scavenging activity and concentration of polyphenolic compounds in various vegetable and fruits (21,22). Our results revealed that quercitrin isolated from Z. schinifolium leaf was one of the major free radical scavengers, acting possibly as a primary antioxidant.…”

“…The DPPH • scavenging activity of the isolated compounds was determined as reported in the literature (Pyo et al 2004) with minor modifications. A methanolic solution (0.2 ml) of each of the test samples (0.02, 0.04, and 0.08 mg/ml) was added to DPPH…”

Hou J.P., Wu H., Wang Y., Weng X.C. (2012): Isolation of some compounds from nutmeg and their antioxidant activities. Czech J. Food Sci., 30: 164-170.Six compounds, licarin-B (1), dehydrodiisoeugenol (2), malabaricone B (3), malabaricone C (4), β-sitosterol (5), and daucosterol (6) were isolated from the seed (nutmeg) of Myristica fragrans Houtt and identified. Among them, malabaricone B was identified for the first time in nutmeg. Antioxidant activities of the isolated compounds were studied using oil stability index (OSI), reducing power, ABTS•+ scavenging, and DPPH • scavenging methods. The resultsshowed that Malabaricone C is an efficient antioxidant agent which exhibits a stronger antioxidant activity than the commonly used synthetic antioxidants in all studied methods. This compound may have a potential to be used as a natural antioxidant in food.
