The aim of this study was to evaluate the bioactive substances in 19 berry cultivars of edible honeysuckle (Lonicera edulis). A statistical evaluation was used to determine the relationship between the content of selected bioactive substances and individual cultivars. Regarding mineral elements, the content of sodium was measured using potentiometry and spectrophotometry. The content of selecte...

Mushrooms are considered rich in proteins, carbohydrates and other nutrients. The present study was carried out to evaluate some edible mushrooms of Kashmir valley for their protein, carbohydrate and lipid contents. The highest protein content was found in Boletus edulis (2.20g) followed by Agaricus bisporus (1.80g), Pleurotus ostreatus (1.68g), Morchella esculenta (1.62g) and Pleurotus sajor c...

In the present investigation, the antioxidant activity and free radical scavenging activity of Crambe cordifolia plant were spectrophotometrically studied. Free radical scavenging activity was determined by DPPH method and the obtained IC value was 1106.65 μg/mL. For comparison, the IC value of standard ascorbic acid 50 50 was 21.69 μg/mL. Antioxidant activity was determined by phosphomolybdate...

The effects of copper pollution on the polyphenol content, color, and antioxidant activity of wine, as well as correlations among these factors, were investigated. Copper had clear influences on wine polyphenol content. At low copper concentrations, the concentrations of nearly all polyphenols increased, and the antioxidant activity values of the wine also increased. When the copper concentrati...

The experiment was established at private apricot orchard near Cacak (Western Serbia) during 2010 and 2011. In the present study we wanted to determine the physicochemical attributes, phenolics content and antioxidant capacity of three new Serbian cultivars (‘Aleksandar’, ‘Biljana’, ‘Vera’) grafted on Myrobalan seedlings. Results indicated that physico-chemical attributes significantly varied a...

The purpose of this study was to determine the possibility of using chokeberry powder as a supplement in apple juice to increase the nutritional value of the final product with the aim of developing a new functional food product. Also, to determine the influence of ultrasound assisted extraction on the bioactive compounds content, nutritional composition and antioxidant potential of apple juice...

BACKGROUND Ultraviolet radiation from sunlight induces overproduction of reactive oxygen species (ROS) resulting in skin photoaging and hyperpigmentation disorders. Novel whitening and anti-wrinkle compounds from natural products have recently become of increasing interest. The purpose of this study was to find products that reduce ROS in 14 Thai plant extracts. METHODS To determine total phe...

The present work was undertaken to evaluate the polyphenolic content, antioxidant and antiviral properties of two wild medicinal plants; Achillea fragrantissima and Nitraria retusa. The crude extracts of both plants were prepared using methanol and ethyl acetate solvents. Generally, total phenolic content ranged from 0.31 to 15.05 mg gallic acid equivalents /g dw, where total flavonoid content ...

The effects of different cooking methods on total bioactive compound content were determined, and in vitro antioxidant activity in 80% ethanolic extracts of Brussels sprouts was evaluated by spectrophotometric methods. Compared to uncooked, steamed, and microwaved Brussels sprouts extracted with 80% ethanol contained higher amounts of total polyphenols. Uncooked Brussels sprouts contained the h...

Grape pomace contains high levels of valuable antioxidants such as anthocyanins and phenolic compounds that help prevent chronic diseases such as cardiovascular problems and cancers. In this study, Concord grape pomace was soaked in acidic solutions at different time intervals and pHs in a water bath at 80 o C. Five kinds of anthocyanins were released and identified in the pomace after acid hyd...
