The present study was designed to evaluate and compare the phenolic (total phenols and flavonoid) contents and antioxidant activity of aqueous extract of Momordica foetida (AEMF) and ethanolic extract of Momordica foetida (EEMF) extract of Momordica foetida leaves; a popular medicinal plant used for traditional medicine preparations. The antioxidant activity of both extracts was assessed using ...

In the present work, we have investigated nutritional, phytochemical content and antioxidant activity of ripe fruits of Ziziphus nummularia Burm. f., one of the underutilized plants distributed in drier parts of North Western India. Fruits were quantitatively analyzed for their total phenolic, flavonoid and flavonol content colorimetrically. Nutritional properties including moisture, fats, carb...

BOBOEV, A., A. HASANOV, L. YOTOVA and H. HASANOV, 2012. Antioxidant activity of peptides obtained from wheat and cottonseed proteins. Bulg. J. Agric. Sci., 18: 103-111 Enzymatic hydrolysis of various wheat proteins and cottonseed with acid (Prolive PAC 30L “EnzymeBioProduct” Ltd, Russia) and neutral proteases (Neutrase, ‘’Novozymes’’, Denmark) was studied. The antioxidant properties of the prod...

The antioxidant potential of N-acetylcysteine amide (NACA), also known as AD4, was assessed by employing different in vitro assays. These included reducing power, free radical scavenging capacities, peroxidation inhibiting activity through linoleic acid emulsion system and metal chelating capacity, as compared to NAC and three widely used antioxidants, alpha-tocopherol, ascorbic acid and butyla...

BACKGROUND Roots of Rumex hastatus (Polygonaceae) are traditionally used for the treatment of various ailments including liver and lung diseases. In this study, various solvent extracts of R. hastatus roots, like methanolic, n-hexane, ethyl acetate, chloroform, butanol and aqueous fractions were assessed through their antioxidant properties in vitro and determination of phenolic contents. MET...

In the last decade, naturally occurring antioxidants continue to play an important role in the food-supplement industry. The content of antioxidants in a plant depends on the species, temperature, humidity, period of growth, harvest month, part of the plant used and many other variables. Herein, we present a new method able to determine the all over antioxidative power (AP) of plant extracts or...

Chestnut shell melanin can be used as a colorant and antioxidant, and fractionated into three fractions (Fr. 1, Fr. 2, and Fr. 3) with different physicochemical properties. Antioxidant activities of the fractions were comparatively evaluated for the first time. The fractions exhibited different antioxidative potential in different evaluation systems. Fr. 1, which is only soluble in alkaline wat...

In the present investigation the acetone extracts of three marine macroalgae Laurentia obtusa, Codium elongatum and Cutleria multifida were tested for antioxidant, antimicrobial and cytotoxic potential. Antioxidant activity was evaluated by free radical scavenging, superoxide anion radical scavenging and reducing power. C. elongatum extract had most potent free radical scavenging activity (IC50...

for many years it was believed that extremely lowfrequency electromagnetic field (elf-emf) do not have any significant biological effects. in this study, the influence of extremely low-frequency electromagnetic fields on the growth performance, serum antioxidant power and gastrointestinal structure of rainbow trout were evaluated. rainbow trout (17-18 g) were exposed to electromagnetic fields (...

objective: dracocephalum kotschyi (lamiaceae family) has been usedin traditional medicine for stomach and liver disorders, headache and congestion. in the present study, we have investigated phytochemical properties and antioxidant activities of dichloromethane, ethyl acetate and methanol extracts of d.kotschyi. material and methods: antioxidant activities of extracts were evaluated using the i...
