AbstractThe aim of this study was to determine the antioxidant activity, total phenolics, total flavonoid, proanthocyanidins, and anthocyanins content of eight berry species, namely serviceberry, gooseberry, blackberry, black chokeberry, bilberry, red currant, black currant, and cornelian cherry harvested in the regions of Sarajevo and Tuzla, Bosnia and Herzegovina. The antioxidant activity was determined by a battery of in vitro tests including DPPH radical assay, FRAP assay, ABTS assay, and phosphomolybdate test for total antioxidant capacity. Total phenolics, total flavonoids, and proanthocyanidins ranged from 0.834 to 6.921 mg TAE (tannic acid equivalents), 0.081–0.673 mg of quercetin, and 0.162–3.247 mg of catechin per gram of fresh fruit, respectively. The water extract of fruits had considerable levels of tested constituents and antioxidant activity, with the highest results obtained for black chokeberry. The multivariate clustering analysis showed that water extracts of analyzed species of berries belong to four distinct types in terms of their antioxidants levels and antioxidant activity. Furthermore, these results support the opinion that employment of multiple antioxidant tests is indeed required for adequate in vitro assessment of antioxidant capacity. Results also emphasized the need for a more detailed evaluation of the fruit species with good antioxidant potential (relative to standards), such as cornelian cherry and gooseberry, which are abundant yet not frequently consumed in Bosnia and Herzegovina.

Aronia melanocarpa L. fruit (common black chokeberry) is one of the most abundant sources of antioxidant compounds in the plant world, superior to all edible fruits; chokeberry fruits contain up to 100 g total phenols per kg fresh material, predominantly (−)epicatechin, cyanidin-3-glycosides and procyanidins (60%), added to quercetin and caffeoyl quinic acid derivates.

AbstractThe total oil content and composition of fatty acids and phytosterols of five Transylvanian (Romania) pomaces of wild and cultivated blueberries (Vaccinium myrtillus), wild cowberry (Vaccinium vitis-idaea) and raspberry (Rubus idaeus), and cultivated black chokeberry (Aronia melanocarpa), were determined by capillary gas chromatography. Out of the five pomace oils, the percentages of polyunsaturated fatty acids (PUFAs) ranged from 37 % to 69 %. The lipid classes analysed (PLs — polar lipids, TGs — triacylglycerols, SEs — sterol esters) were separated and identified using thin-layer chromatography. TGs showed the highest PUFAs content (ranging from 41.9 % to 72.5 %) and PUFAs/SFAs (saturated fatty acids) ratios (in the range of 5.8–33.1 %). In the case of PL and SE fractions, the levels of SFA were significantly higher than in TGs. The total amount of sterols was in the range of 101.6–168.2 mg per 100 g of lipids of the pomaces analysed. The predominant phytosterols were β-sitosterol, stigmastanol + isofucosterol, and campesterol. The results indicated that the investigated pomace oils, due to their good balance between n-6 and n-3 fatty acids (except for chokeberry) and high β-sitosterol content, could be excellent sources of PUFAs and phytosterols, thus suggesting potential value-added utilisation of berry waste oils for preparing functional foods or food supplements.

Chokeberry fruits can be treated as very rich sources of bioactive compounds and, therefore, have a very high biological value. The purpose of the study was to compare selected chemical and physical properties of chokeberry fruits, both from organic and conventional cultivations located near Cracow. Chemical composition of the fruit, content of the antioxidant activity, bioactive compounds, and ultra-weak luminescence were analyzed. It was proved that chokeberry fruits are rich in bioactive compounds and that ecological crops produce fruits with a higher level of such compounds. Chokeberry fruits from organic farms were proven to have a higher content of bioactive ingredients and antioxidant activity than in traditionally grown fruits. The total amount of sugars was ambiguous because both the highest and the lowest values were determined in fruits from traditional cultivation. Photon emissivity determined on the basis of ultra-weak luminescence was higher in fruits from organic cultivations. A very high correlation was also found between the photon emissivity and the content of polyphenols as well as the antioxidant activity.

Anthocyanins is a natural edible pigment with many health benefits. The aim of this work was the identification of anthocyanins present in <i>Aronia melanocarpa</i> using mass spectrometric features. The anthocyanins of the <i>A. melanocarpa</i> were analyzed by UV-Vis, HPLC-DAD and LC-EIS/MS methods. The four important anthocyanins were identified as follows: cyanidin-3-galactoside (68.68%), cyanidin-3-arabinoside (25.62%), cyanidin-3-glucoside (5.28%) and cyanidin-3-xyloside (0.42%). Among the four anthocyanin monomers, three anthocyanins with the highest content of <i>A. melanocarpa</i> were selected, and the antioxidant activity was studied with the total anthocyanins. The antioxidant capacity was cyanidin-3-galactoside > total anthocyanin > cyanidin-3-arabinoside > cyanidin-3-glucoside. The activity of the four anthocyanin samples was greater than ascorbic acid. The methodology described in this study will provide an effective tool for anthocyanins identification. Our results suggested that anthocyanins from <i>A. melanocarpa</i> exhibited effective antioxidant activity. These findings may be crucial in future research concerning chokeberry based functional food products.

The interest in berries from food manufacturers is huge, which is explained by good organoleptic characteristics and high biological activity of berries. One way to preserve the properties of berries throughout the year is to obtain extracts. Determining the conditions and type of optimal extraction technology to obtain biologically active substances from plant materials is an important stage in the production of new natural preventive additives. The aim of this work is to study the chemical composition and antioxidant activity of blueberry extracts (Vaccinium myrtillus L.) obtained by various methods: maceration, ultrasonic and microwave extraction. The use of ultrasonic extraction as a method of intensifying the process of extracting biologically active compounds from blueberries is very effective. This proves an almost 2-fold increase in the flavonoid content in the extracts. However, the content of anthocyanins in the extracts of blueberries is not the highest for ultrasonic extraction (a decrease by 3.3 times compared with maceration), in all likelihood due to the instability of this class of compounds in this type of processing. Among the extracts of blueberries obtained by three technologies (maceration, microwave and ultrasound treatment), it is the ultrasound extract that has the highest antioxidant activity (9.5±0.1 mg/cm3, 18.18 mmol±0.24 Fe2+/1 kg, 58.6%), determined by three methods: DPPH method, FRAP method, method for assessing antioxidant properties using a model system with linoleic acid. Ultrasonic extraction was chosen as a technology for obtaining a concentrated blueberry extract.
