Antioxidant Capacity of Several Romanian Forest Fruits (Rosa canina L., Prunus spinosa L., Vaccium vitis-idaea L. and Cornus mas L.)

The comparison of the antioxidant activity of the studied forest fruits emphasized a hierarchy of the antioxidant capacity in rosehip, blackthorn, lingonberry and cornelian cherry. The purpose of the study was to investigate the antioxidant capacity and nutritional value of rosehip, blackthorn, lingonberry and cornelian cherry. In the current study, the FT-IR spectroscopy technique was applied to detect molecular components in forest fruits samples. Antioxidant capacity was evaluated with photochemical assay as well as humidity, protein, fibre, lipid and carbohydrate content. The FT-IR results revealed the presence of different bio-active compounds in berries such as flavonoids, tannins, sugars, acids, proanthocyanidins, carotenoids, citric metabolites and others. The highest antioxidant capacity was observed in rosehip 105.67±1.38 and blackthorn 49.89±1.92 (μg/mg equivalent ascorbic acid). Regarding nutritional parameters, rosehip showed the most increased content of protein displaying average values of 1.60, carbohydrates 38.20 and fibre 24.10 (g/100 g/sample). These results can provide useful information providing a research interest for the identification of new molecular compounds from Romanian flora samples. ********* In press - Online First.

The comparison of the antioxidant activity of the studied seeds of fiber crop (hemp and flax) emphasized a hierarchy of antioxidant capacity. The purpose of the study was to investigate the antioxidant capacity and nutritional value of flax seeds (Linum usitatissimum L.) and hemp seeds (Cannabis sativa L.) in powder form. In this study, the FT-IR technique was utilized in order to detect molecular components in analyzed samples. Antioxidant capacity was evaluated with photochemical assay as well as humidity, protein, fiber, lipid and carbohydrate content. The FT-IR results reveal the presence of different bio-active compounds in hemp such as flavonoids, tannins, sugars, acids, proanthocyanidins, carotenoids and citric metabolites. The highest antioxidant capacity was observed in flax seeds, 18.32 ± 0.98, in comparison with hemp seeds, 4 ± 0.71 (μg/mg dry weight equivalent ascorbic acid). Regarding nutritional parameters, flax seeds showed the most increased content of protein, displaying average values of 534.08 ± 3.08, as well as 42.20 ± 0.89 of lipids and 27.30 ± 0.89 of fiber (g/100 g/sample). Hemp seeds showed the highest protein content of 33 ± 1.24 (g/100 g/sample).

Abstract Cornelian cherry (Cornus mas L.) is a plant growing in Central and Eastern Europe. Its fruits are a rich source of anthocyanins, flavonoids and iridoids. Among the iridoids, loganic acid is the most prevalent. The study aimed to examine the relation between loganic acid content, antioxidant capacity and hypoglycaemic effect in vivo for three Polish cultivars of C. mas. All tested cultivars strongly inhibited α-glucosidase and had similar amounts of highly bioabsorbable loganic acid. The loganic acid content was similar for each cultivar tested, while the cultivars differed in content of flavonoids and anthocyanins. The highest antioxidant potential was observed in the fruits of cv. Szafer, and the highest α-glucosidase inhibitor was cv. P5. A statistical analysis has shown that hypoglycaemic properties are prevalently driven by anthocyanin content and the antioxidant capacity, especially ferric-reducing ability partially based on loganic acid.

A number of selected cornelian cherry wild genotypes were investigated regarding antioxidant capacity, total phenols, total flavonoids and colour component. The total phenolic, total flavonoids and antioxidant activity of methanol extract of cornelian cherry fruits were determined using Folin-Ciocalteu, colorimetric and DPPH methods, respectively. Total phenolic content ranged from 163.69 (S1) to 359.28 (H2) mg GAE 100 g-1 FW. Genotypes H2 and H3 had the highest total phenolic content (359.28 and 343.50 mg GAE 100 g-1 FW, respectively), total flavonoids (54.26 and 64.48 mg QE 100 g-1 FW, respectively) and antioxidant capacity (2.39 and 2.71 mmolTrolox100g-1 FW, respectively). Significant differences of yellow/blue color component (b*), red/ green (a*) color component, values of lightness (L*) and chroma (C) were obtained for extracts from fruits. The present study shows the potential of certain cornelian cherry genotypes as valuable source of natural antioxidants and gene stock for breeding programs.

The aim of this research was to evaluate the physicochemical quality, antioxidant capacity and nutritional value in tuberous roots of some wild dahlia species. The experiment was carried out in the Department of Plant Science of the Autonomous University Chapingo, Mexico. Plants were established in a randomized complete block design with five replications. The total soluble solids (TSS), titratable acidity (TA), vitamin C (VC), total phenols (TP), antioxidant capacity (AC), inulin and its proximate composition were evaluated. Among the materials analyzed, the most outstanding wild species were Dahlia campanulata, D. coccinea and D. brevis, where D. campanulata stood out for its concentration of VC (0.05 mg 100 g-1), AC (1.88 mg VCEAC g-1), inulin, DM and TC (72.25, 24.38 and 88.37%, respectively), however, the inulin content was similar to D. coccinea (66.17%), which was also outstanding with respect to the content of TP (1.74 mg GA g-1). Likewise, D. brevis presented the highest values of RFi (5.49%) and A (78.42%). According to our results, the tuberous roots of wild dahlia species can be used as food, as well as being a source of selection of traits of nutraceutic interest for genetic improvement. ********* In press - Online First.

Ft Ir Spectroscopy

Fourier transform infrared (FT-IR) spectroscopy is a physicochemical technique based on the vibrations of a molecule energized by infrared radiation at a specific wavelength range. Abiotic stresses can induce the production of secondary metabolites, increasing bioactivity. The objectives of the study were to evaluate the impact of heat treatments on the bioactivity of pineapple by-products, and whether FT-IR analysis allows understanding of the changes imparted by abiotic stress. The by-products were treated at 30, 40, and 50 °C for 15 min, followed by storage at 5 ± 1 °C for 8 and 24 h. Lyophilized samples were characterized for total phenolic content and antioxidant capacity and analyzed by FT-IR. Thermal treatments at 50 °C reduced the content of phenolic compounds (21–24%) and antioxidant capacity (20–55%). Longer storage time (24 h) was advantageous for the shell samples, although this effect was not demonstrated for the core samples. The principal components analysis (PCA) model developed with the spectra of the pineapple shell samples showed that the samples were grouped according to their total phenolic compounds content. These results allow the conclusion to be drawn that FT-IR spectroscopy is a promising alternative to the conventional chemical analytical methodologies for phenolic and antioxidant contents if there are significant differences among samples.

This study was carried out on 13 local cornelian cherry (Cornus mas L.) genotypes grown in Yusufeli (Artvin) in Northeast Anatolia in Turkey. Cornelian cherry fruits from these 13 genotypes were harvested and analyzed during the ripening period in 2010. Some physical and chemical characteristics of cultivars were determined. Fruit weight and fruit flesh ratio of these genotypes ranged from 2.72 to 4.11 g and 79.08 to 89.99%. Soluble solid content were determined the lowest as 13.7% and the highest as 18.6%. The genotypes had vitamin C between 31 to 70 mg/100 g with average of 50 mg/100 g. Total protein, cellulose, tannin and ash content of genotypes were determined between 0.75-2.18%; 0.36-1.08%; 0.57-1.28% and 0.51-1.13%. The genotypes were found to be free of pest and diseases. The present study showed that there were enough variability among cornelian cherry genotypes grown in same ecological conditions of a small area and these genotypes could be important both to improve nutritional value through germplasm enhancement programmes and to use them in organic production.
