Mercury poisoning is responsible for inducing serious adverse effects in living organisms. One of protection factors could be substances proven to possess high antioxidant and metal chelating activity – plant polyphenols. There are many sources of polyphenols in plant kingdom but the most interesting for food industry could be widely consumed herbs. Aim of the research was to evaluate antioxida...

The present paper examines the chemical composition and antioxidant capacity of free volatile aglycones from basil compared to their essential oil. The comparison of chemical composition of volatile aglycones with the chemical composition of essential oil reveals four common compounds: eugenol, chavicol, linalool and a-terpineol. For the evaluation of the mentioned antioxidant capacities, two d...

Oxidative stress is characterized by an imbalance in the generation of free radicals and their subsequent elimination endogenous antioxidants. It a characteristic several diseases, especially during progression stage, which can lead to fatal effects. This study aims investigate phytochemical components antioxidant capability Tamarindus indica assess its as candidate for managing diseases associ...

A single dose of polyphenols comprised in a beverage based on fruit juices did not significantly increase the content of total phenolics neither in plasma nor in serum. How-ever, the ingestion of 500 mL beverage significantly enhanced the antioxidant capacity in plasma (FRAP) as well as in serum (FRAP, TRAP), reaching the peak after different times (30-60 min). In addition, the photochemilumine...

Research and development of natural antioxidants are gaining popularity with their wide application in food medicine. Papaya (Carica papaya L.), a plant medicinal value, is widely planted tropical regions. This study was conducted to compare the tissues different organs as well leaves flowers 9 cultivars papaya. The three methods, namely, 2,2’-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging...

Objective: Allium elburzense is an endemic plant of the family Amaryllidaceae that grows wild in northern Iran with some nutritional and medicinal applications. The present study was aimed to investigate the fibrinolytic and antioxidant effects of A. elburzense bulb extracts. Materials and Methods: Hydroalcoholic, aqueous, chloroformic and butanolic extracts were evaluated in this research. In ...

Canned and bottled tea drinks contain not only green tea epicatechins (GTE), namely (-)-epigallocatechin gallate (EGCG), (-)-epicatechin gallate (ECG), (-)-epigallocatechin (EGC) and (-)-epicatechin (EC), but also four GTE epimers, namely (-)-gallocatechin gallate (GCG), (-)-catechin gallate (CG), (-)-gallocatechin (GC) and (-)-catechin (C). In the present study we examined the antioxidant acti...

A greenhouse experiment was conducted to evaluate the comparison of nutrient use efficiency, antioxidant assay, and nutritional quality butter-head lettuce in five cultivation systems. For this experimental study, a split-boxes arrangement completely randomized design (CRD) with three aeroponics systems (high pressure (T1), low (T2), ultrasonic nozzle (T3)), hydroponic system (T4), conventional...

Background: Cornus sanguinea L subsp australis (C.A. Mey.) Jáv. (Cornaceae) is a native species in north and northwest of Iran. It is locally named Siah-al. The genus Cornus is rich source of anthocyanins. Objective: In this study the antioxidant activity, total phenol and total anthocyanin contents of different extracts of C. sanguinea L subsp australis. were investigated for the first time. ...
