“…17,18 As shown in Figure 1, HPLC analysis allowed identification of 12 individual anthocyanins being glucosides, galactosides and arabinosides of five anthocyanidins (delphinidin, cyanidin, peonidin, malvidin, petunidin). In general, the anthocyanin profile of the Bulgarian bilberries studied is similar to that reported for bilberry fruits from Italy, 6 Finland 7 and Slovenia. 19 In line with these studies, delphinidin glycosides were the predominant compounds ( Table 2).…”

“…Identification and quantification of individual anthocyanins was performed as previously reported by Giovanelli et al 6 using a Waters HPLC system (Waters, Millford, USA) equipped with a model 600 pump, a model 2996 photodiode array detector and Empower 2 data management programme. The column used was a C18 Spherisorb ODS 2 (4.6 mm×250 mm, Waters, Millford, USA).…”

“…4,5 The antioxidant activity is strongly dependent on the berry species, wild berries having generally higher total antioxidant capacity than the cultivated ones. 6 However, extensive variations in the anthocyanin content have recently been observed for the bilberry populations, 7 indicating a high degree of environmental influence. Furthermore, the proportions of specific anthocyanidins in bilberries differ between altitudes and between plants with different parental origins.…”

Antioxidant capacity of Bulgarian bilberry (Vaccinium myrtillus L.) fruits from two different picking regions, Velingrad and Troyan, was studied using the FRAP (ferric reducing antioxidant power) assay and amperometric method. In addition, the anthocyanin composition was characterised by high performance liquid chromatography -diode array detection. Antioxidant capacity of the bilberries from the region of Velingrad was 15 and 20% higher than that of the Troyan region sample for the FRAP and EC +0.5 V values, respectively. Among the 12 individual anthocyanins identified, delphinidin glycosides were the predominant compounds. In accordance with the content of total anthocyanins, higher concentrations (20-64%) of individual compounds were observed for the bilberries from the region of Velingrad. The results obtained demonstrate that the environmental conditions within the picking regions have significant effects on the antioxidant capacity and anthocyanin content of Bulgarian bilberry fruits, which may affect their applications as functional foods or ingredients.

“…A large number of reports (Alvarez-Jubete, Wijngaard, Arendt, & Gallagher, 2010; Giovanelli & Buratti, 2009;Pandey & Rizvi, 2009) have found a strong association between phenolic compounds and antioxidant activity in plants. However, opposite statement that no or little correlation between phenolic compounds and antioxidant activity also exists (Nsimba, Kikuzaki, & Konishi, 2008).…”

Effect of sulfation on the antioxidant properties and in vitro cell proliferation characteristics of polysaccharides isolated from corn bran

Polysaccharides were extracted from corn bran (CBPs) and then modified by a sulfating reaction to obtain sulfated corn bran polysaccharides (SCBPs). Synthesized sulfated polysaccharides were located in the equatorial bonds of monosaccharide residues. A more orderly and smooth surface of SCBPs was observed. Single factor experiment results showed 2.0 g of aminosulfonic acid, 60 mL of N-dimethylformamide and 2.5 h of reaction time were the optimum conditions for SCBPs preparation. Phenolic content of SCBPs significantly decreased with increasing concentration of aminosulfonic acid, while it increased with increasing DMF concentration and reaction time. SCBPs had higher DPPH, ABTS and iron chelating capacity under the optimum conditions. SCBPs significantly inhibited the proliferation of A549 and HepG2 cell lines, which was associated with the upregulation at the mRNA expression level of pro-apoptotic genes CASP3, CASP8, CASP9 and reduced expression of p53, gene Bcl-2 and gene iNOS.

“…Many of these health benefits are due to the action of antioxidant molecules such as ascorbic acid (vitamin C), α-tocopherol (vitamin E), carotenoids, polyphenols (a wide class of components including phenolic acids, catechins, flavonols and anthocyanins) and caffeine, in which plants are naturally rich (Giovanelli & Buratti, 2009;Jehad, 2009). The current state of medical knowledge attributes to antioxidant molecules a crucial role in counteracting the effects of oxidative stress caused by Reactive Oxygen Species (ROS), such as superoxide anions, hydrogen peroxide, and hydroxyl, nitric oxide and peroxynitrite radicals.…”

It has already been acknowledged among the medical community that plant based treatments represent an interesting contribution to modern therapeutics due to the presence in their composition of molecules with pharmacological and antioxidant action. The aim of this study was to evaluate the contents of total phenolics, flavonoids, and caffeine in six plants used traditionally by healers in Portugal and usually consumed as tea or infusion namely: Camellia sinensis, Melissa officinalis, Lippia citriodora, Cymbopogon citratus, Matricaria chamomilla, and Tilia cordata. Total phenolics ranged from 32.05 mg GAE/100g for aqueous extracts obtained from leaves of L. citriodora to 145.28 mg GAE/100g for aqueous extracts of C. sinensis. Significant variations in the flavonoid content were also found among analyzed plants and depending on the nature of the extract, with C. sinensis standing out again with the highest values (78.31 mg CE/100g) and the ethanolic extract obtained from the flowers of T. cordata exhibiting the lowest content (25.15 mg CE/100g). The concentration of caffeine was also very diverse and followed the sequence M. officinalis < T. cordata < C. citratus < M. chamomilla < L. citriodora < C. sinensis. The antioxidant activity of each plant was evaluated in vitro using a standard model system, the DPPH assay, and was found to vary according to C. citratus (90.9%) > C. sinensis (87.8%) > M. officinalis (50.7%) > M. chamomilla (45.3%) > T. cordata (32.2%) > L. citriodora (28.0%). The aqueous extracts presented lower antioxidant activity than the corresponding ethanolic ones.
