Opis:
In this study, DPPH radical scavenging activity, ABTS radical cation decolorization assay, FRAP reducing power, total phenolic content, total flavonoid content and phenolic compounds of leaves of plants, grown in Afyon/Turkey were investigated. These plants were poppy, daisy, dandelion, manger, chickweed, black chicory and white chicory. Phenolic acids including gallic acid, ferulic acid, chlorogenic acid, coumaric acid, ellagic acid, vanilic acid, caffeic acid, cinnamic acid, 4-hydroxybenzoic acid, 2,5-dihydroxybenzoic acid and flavonoids including catechin, apigenin, naringin, rutin and quercetin amounts in leaves were determined. Among plants leaves, leaves of daisy and manger had statistically highest DPPH value and leaves of poppy and dandelion had statistically highest ABTS value, while leaves of White chicory had statistically highest FRAP value, total phenolic content and total flavonoid content. Leaves of black chicory and white chicory had higher phenolic compounds compared to that of other plants. These results suggest the using of these leaves as sources of natural antioxidants.

Opis:
Although the term 'antioxidant' is used very frequently, there are problems with the definition of antioxidants and estimation of antioxidant activity. The distinction between antioxidant and antiradical activities is not always obvious. This minireview discusses critically the principles, advantages and limitations of the most frequently used methods of estimation of antiradical and antioxidant activities.

Opis:
The aim of this project was to compare the effect of Rhizobacterium rhizogenes infection, and subsequent hairy root induction, on the antioxidant capacity of in vitro root cultures derived from two tomato cultivars differing in flavonoid biosynthetic potential. Tomatoes and especially processed tomatoes are rich in lycopene ,which is one of the most powerful antioxidants. Antioxidan capasity of normal (wild) roots from Kumato and Cherry seeds and transformed roots from infected cotyledons with agrobacterium was determined by the DPPH metod. The results presented in this paper indicate that the normal roots extracts and extracellular had higher antioxidants capasity than transformed roots but antioxidant capasity was higher in the extracellular than in the roots extract. Standard deviation was higher in extracellular than roots extract. This experiment was valuable because antioxidants protect human body against oxidative stress which can cause many diseases such as diabetes and accelerate the aging process of the organism.

Surowcem do produkcji perry jest przefermentowany sok z gruszek, zwany moszczem gruszkowym. Celem niniejszej pracy było oznaczenie i porównanie potencjału antyoksydacyjnego jako całkowitej zawartości polifenoli oraz aktywności antyutleniającej w próbkach napojów fermentowanych typu perry dostępnych na rynku Trójmiasta. W ramach prowadzonych badań metodą spektrofotometryczną oznaczono ogólną zawartość polifenoli z zastosowaniem odczynnika Folina-Ciocalteu’a oraz aktywność przeciwrodnikową z wykorzystaniem rodnika DPPH·. Uzyskane wyniki wskazują na zróżnicowane właściwości perry dostępnych na polskim rynku pod względem zawartości polifenoli ogółem (140,44÷351,62 mg/l) oraz zdolności do wymiatania wolnych rodników. Napoje imitujące perry zawierają znacznie niższe wartości polifenoli ogółem średnio 133,71 mg/l w stosunku do średniego wyniku perry 225,50 mg/l. W wyniku przeprowadzonych badań stwierdzono, że właściwości przeciwutleniające napojów fermentowanych typu perry są słabsze w porównaniu z właściwościami cydrów i win.

Opis:
Antioxidants are chemical compounds that scavenge free radicals in organisms and protect most important biomolecules such as DNA, proteins, lipids from their damaging activity. Antioxidants reduce a risk of cancer, inflammations, arthritis, cardiovascular diseases and others. The objective of this study was to prepare extracts of different tea species (Camellia sinensis, Aspalathus linearis) in order to compare their antioxidant and radical scavenging activities using reaction detection. Methanolic black, green and red tea extracts were prepared. Reaction detection was used for on-line determination of free radicals of 2,2-diphenyl-1- picrylhydrazil (DPPH) binding by high performance liquid chromatography.

The experiment on Zea mays L. cv. Landmark (F1) plants was performed in a greenhouse with UV-B (305–315 nm). The pots with plants were divided into four groups: the first and the second groups were grown, respectively, at low (1.0 kJ m -2 d -1 ) and high (3.0 kJ m -2 d -1 ) biological effective dose of UV-B radiation. Half of the pots of each group were sprayed with 0.1% solution of Asahi SL (the third and fourth groups). The intensity of photosynthe- sis and transpiration, chlorophyll fluorescence, the content of UV-absorbing compounds and radical scavenging activity were measured using DPPH after four and six weeks of UV-B radiation. After six weeks of irradiation with a higher UV-B dose both flavonoid content and antioxidant activity increased by 112% and by 44%, respectively, compared to the plants grown at the lower dose. The plants treated with Asahi SL and exposed to the high dose of UV-B had the content of flavonoids 80% higher than the control ones. Asahi SL decreased scavenging activity in both groups of plants by 17% and 32%, respectively, in comparison with the untreated plants. The intensity of net photosynthesis, the transpiration rate and chlorophyll fluorescence parameters (Fv/Fo, ETR, Rfd) did not differ in most of variants.

Opis:
The aim of this study was to determine total phenolic and flavonoid contents and to evaluate the antioxidant activities of two honeys and one propolis sample, collected from the region of Laghouat (South of Algeria). Total phenolic content were determined by using Folin-Ciocalteu reagent as gallic acid equivalent, while flavonoids content was assessed by means of the AlCl3 method as Rutin equivalent. Antioxidant activities of the honeys and propolis were examined by two different methods, namely, scavenging of free radical 2,2-diphenyl-1-picrylhydrazyl and reducing power. The antioxidant activities were compared with standard antioxidants such as Ascorbic acid, BHT and Trolox. The highest level of phenolic was 2385 mg Gallic acid per 100g sample, the highest level of flavonoid was 379 mg Rutin per 100g sample, while the highest protein content was 1177 mg per 100g sample, DPPH (0.026 mg/ml) and TEAC (0.0015) were detected especially in the propolis sample, indicating that it holds good antioxidant properties. A strong positive correlation was found between phenolics, flavonoids, DPPH and TEAC, indicating that in addition to total phenolic content, flavonoid and protein concentrations are good indicators of the antioxidant potential of propolis and honey.

In this study, the ability of hexane (HSE), chloroform (CSE), ethyl acetate (EASE) and methanolic (MSE) stems extracts from Phragmites australis or EDTA (as standard) to chelate iron using ferrozine method or zinc and copper using the murexide method is carried out in vitro. When the increased volumes of the HSE studied were taken from a stock solution of a fixed concentration 1 mg/ml at 25–175 μl for the iron and zinc chelating assay, 1–7 mg/ml for the copper chelating assay gave a significant (p≤ 0.01) activity. The obtained results showed that the HSE have the highest capacity to chelate ferrous ions below the EDTA (standard chelator) with absorbance arrive to the lesser extent 0.24±0.005, 0.04±0.013 which expresses 86% and 97% (compared to the control) of inhibition, respectively. For the murexide chelation, the results obtained also showed that the HSE and EDTA have a good (p≤ 0.01) chelating dose dependent effect towards zinc and copper ions with increased absorbance 0.45±0.02 and 0.42±0.02 with 54% and 56% of inhibition, respectively, for the zinc chelation and 0.66±0.03, 0.13±0.005 represent 44% and 88% for copper chelation. In contrast to the antioxidant capacity, the extract of hexane, ethyl acetate, chloroform and methanol from leaves, stems and roots of the Phragmites australis plant have a very low scavenger effect to the radical DPPH where the maximum inhibition is approximately 13.79%, obtained with the maximum volume. Finally, the HPLC analysis of effective extract (HSE) confirmed the presence of oxalic, citric, malic, succinic, fumaric, formic, acetic, propionic and butyric or iso butyric acid.

Opis:
Spirulina platensis is a microalga that contains a lot of secondary metabolites and is utilized as a dietary supplement. It can inhibit fat peroxidation better compared to the chemical antioxidant. Laboratory-scale closed reactor system was designed for Spirulina cultivation. This research aims to analyze identified secondary metabolite (Phytochemical contents) and the antioxidant activity or value of Inhibition Concentration 50% (IC50) of the fresh lab-scale cultivated Spirulina platensis. The antioxidant content was evaluated using DPPH method (1,1–diphenyl-2-pikrilhidrazil) on various sample concentrations as well as using Vc (Ascorbic Acid) as a positive control. The principle of hydrogen absorption by free radicals from antioxidants was demonstrated with the absorption value using a spectrophotometer at a wavelength of 517 nm. The results show that Spirulina platensis lab-scale cultivation was resulting in 5.0±0.01 g/10.0 L wet basis on the 10th day. The results show that Spirulina platensis has positive compounds of flavonoid, steroids, triterpenoids, phenolic, and saponins. Fresh Spirulina platensis has a value of IC50 647.045 ppm and Vc as a positive control has the IC50 of 2.085 ppm. The potential as a source of natural antioxidants was categorized as a very weak capacity. Therefore this study can be concluded that Spirulina platensis cultivated in Laboratory-scale has a potential to act as antioxidant candidate.

Celem pracy było wyznaczenie współzależności między zawartością polifenoli ogółem i zdolnością do dezaktywacji rodników DPPH wybranych miodów pszczelich. Materiał badawczy stanowiły 43 próbki nektarowych miodów pszczelich 12 różnych rodzajów, wśród których było 7 rodzajów miodów powszechnie spożywanych (wielokwiatowy, gryczany, akacjowy lipowy wrzosowy, nektarowo-spadziowy oraz rzepakowy) oraz 5 rodzajów miodów „niszowych”. Wyniki badań pozwoliły stwierdzić, że istnieje silna dodatnia korelacja pomiędzy zawartością polifenoli ogółem a zdolnością do dezaktywacji rodników DPPH, o czym świadczy wysoki współczynnik korelacji r = 0,976.

In this work the studies on the antioxidative properties of extracts from various morphotic parts of the ground elder (leaves, rhizomes, seeds and flowers) were presented. Moreover, the effect of different extraction methods (ultrasonic assisted extractions, extraction in a Soxhlet apparatus, extraction at the boiling point of the solvent used), solvent and its amount, and extraction time on the antioxidative properties of the obtained extracts were tested. The studies showed that all parts of ground elder can show radical scavenging activity, and it depends mainly on the method of extraction and extraction time. But the most beneficial is ultrasonic assisted extraction which used lower amount of solvent (ethanol). In case of all parts of the ground elder (leaves, rhizomes, seeds and flowers) it allows to obtain very high values of the antioxidant capacity (above 90%) for very short extraction time amounted to 20–40 minutes.

The increase in the costs of storage and disposal of post-production residues has resulted in the search for new directions for their recycling, which is closely related to the necessity of protecting the natural environment and promoting a circular economy. Moreover, the apparent interest shown by the food market in raw materials with high antioxidant activity implies an increasing use of by-products. The objective of the study was to determine the effect of the type and concentration of the solvent on the efficiency of extracting polyphenols from distillery stillage as well as their antioxidant activity by using several solvents: methanol:water (70:30 v/v), methanol:water (100:0 v/v), ethanol:water (70:30 v/v) or ethanol:water (100:0 v/v). The DPPH radical method was used to determine the antioxidant activity of the obtained extracts. The normalised variable (NV) and statistical measure (MS) were determined, based on which the effectiveness of the solvents was evaluated. The highest polyphenolic content and the antioxidant activity were obtained by using ethanol:water (70:30 v/v) as a solvent in the extraction of polyphenolic compounds from distillery stillage.

Opis:
Pulses are a vital source of plant-based proteins and amino acids for people around the globe and should be eaten as part of a healthy diet to address obesity, as well as to prevent and help manage chronic diseases such as diabetes, coronary conditions and cancer; they are also an important source of plant-based protein for animals. Pulses provide protein and fibre, as well as a significant source of vitamins and minerals, such as iron, zinc, folate, and magnesium, and consuming half a cup of beans or peas per day can enhance diet quality by increasing intakes of these nutrients. The present attempt deals with comparison antioxidant activities of various sprouts of selected pulses. The β-carotene, ascorbic acid, total antioxidant activity, total phenol and flavonoid content of black gram (Vigna mungo), cowpea (Vigna unguiculata), desi chickpea (Cicer arietinum), and yellow mustard (Brassica alba) seeds and their sprouts (48 h) were determined. The parameters selected reflect the antioxidant capacity with respect to the dietary antioxidants (β-carotene, ascorbic acid) which were noted to be highest in chickpea sprouts and black gram sprouts respectively. The highest antioxidant activity in terms of % DPPH inhibition (49.837 ± 0.61 % ) and flavonoid content ( 211.06 ± 8.17 mg/100g ) was observed in cowpea sprouts. The highest total phenol content was noted in yellow mustard sprouts (58.45 ±6.67 mg/100g). Inclusion of pulses in the diet is a healthy way to meet dietary recommendations and is associated with reduced risk of several chronic diseases including cancer. Long-term randomized controlled trials are needed to demonstrate the direct effects of pulses on the cancer like diseases.
