Andean blackberries (Rubus glaucus Benth) are fruits rich in phytocomponents with high antioxidant activity. In this work, the changes in the total polyphenol content (TPC), the total flavonoid content (TFC), and the total anthocyanin content (TAC) of four blackberry varieties at three maturity stages (E1-25%, E2-50%, and E3-100%) were measured. The antioxidant activity (AA) was evaluated using the 2,2’azinobis-(3-ethylbenzthiazolin 6-sulphonic acid (ABTS) and ferric reducing antioxidant power (FRAP) methods. TPC and TFC content decreased with the increase in the maturity stage. The blackberry Brazos cultivar presented TPC values of 51.26, 38.16, and 31.59 mg of gallic acid equivalents (GAE)/g dry weight (DW) at E1, E2, and E3, respectively. The TAC and soluble solids increased with the increase in the maturity stage of the fruits. The Andimora variety at E3 presented a high TPC content, and the Colombiana variety presented a high TFC content. The blackberry Colombiana cultivar presented TAC values of 1.40, 2.95, and 12.26 mg cy-3-glu/100g DW at E1, E2, and E3, respectively. The blackberry Colombiana cultivar presented a high AA value at 1278.63 µmol TE/g DW according to the ABTS method and 1284.55 µmol TE/g DW according to the FRAP method. The TPC and TFC showed a high correlation with the AA according to the ABTS and the FRAP methods. The Pearson correlation between the TFC and AA/ABTS has a value of r = 0.92. The TFC and AA/FRAP present a value of r = 0.94.

AbstractThe study evaluated some agro-morphological (fruit weight, fruit flesh ratio, fruit skin colour, number of fruits per raceme, number of racemes per bush), biochemical (vitamin C, soluble solids content, organic acids), and bioactive (total phenolics, total anthocyanins, total flavonoids, and antioxidant capacity) characteristics of the fruit of a number of selected European Cranberrybush (Viburnum opulus L.) genotypes grown in the Sivas province of Turkey. To evaluate the antioxidant capacity, ferric reducing antioxidant power (FRAP) assays were performed. The results showed genotype-specific differences in most of the agro-morphological, biochemical and bioactive characteristics. The range of fruit weight, number of fruits per raceme, and number of racemes per bush was between 0.67 and 0.82 g, 40.7 and 57.1, and 470 and 581, respectively. The highest vitamin C and soluble solids contents were found in the fruits of genotypes SIV-9 and SIV-6 as 39 mg per 100 g and 12.6%, respectively. Tartaric acid was the main organic acid in all the genotypes; it ranged from 120 to 144 mg per 100 g of fruit FW. Total phenolic, total anthocyanin and total flavonoid contents ranged from 621 to 987 mg gallic acid equivalents per 100 g, 15 to 51 mg cyanidin-3-rutinoside equivalents per 100 g, and 202 to 318 mg rutin equivalents per 100 g, respectively. Genotype SIV-10 had the highest antioxidant capacity (34.90 μmol Trolox per g, based on FRAP assays). The present study shows the potential of the evaluated European Cranberrybush genotypes for improving the nutritional value through germplasm enhancement programmes.

This study aimed to determine the influence of maturity stages and processing methods (blanching and steaming) on the antioxidant profile and in vitro antioxidant activities of bignay (Antidesma bunius (Linn.) Spreng var. Kalabaw) flesh and seeds. Bignay fruits of three maturities (unripe, half ripe, and fully ripe) were collected from Laguna, Philippines. Each maturity stage was subdivided into three lots. One lot underwent blanching at 90 ± 5°C for 2 minutes, and another underwent steaming at 105 ± 5°C for 5 minutes while the last did not undergo treatment. Seeds of the samples were then separated from the flesh. Both seeds and flesh were freeze-dried, extracted, and analyzed for antioxidant contents (total phenolic content, total flavonoid content, and total anthocyanin content) and antioxidant activity by DPPH, ABTS, and FRAP assays. Results show that both the maturity and processing methods significantly affect the antioxidant content and activity of the samples. Moreover, except for the FRAP assay done on flesh samples, all assays showed that there is significant interaction between the effect of maturity and processing method on the antioxidant contents and activity of bignay flesh and seeds. Results also show that fully ripe flesh and seeds yielded greater antioxidant content and antioxidant activity than their half-ripe and unripe counterparts; whereas, blanched flesh and seeds generally had higher antioxidant activities than their unprocessed and steamed counterparts.

The aim of this study was to evaluate the effect of microfiltration (MF) on the antioxidant capacity of elderberry juice using ceramic membrane. Previous to MF measurements preliminary examination was achieved with different enzymes. Four different samples were prepared: one without any enzyme and three with different pectolytic enzymes. The resistances were determined using the resistance-in-series model and difference between four enzyme-treated samples are evaluated. The effect of this technology on the antioxidant component of the clarified elderberry juice has been evaluated in permeate and retentate samples. For ferric reducing antioxidant power was measured with FRAP and total phenolic content (TPC) was determined with Folin Ciocalteau reagent. The total anthocyanin content (TAC) was estimated using spectrophotometric method. Higher juice yield was obtained using enzyme compared with enzyme-free elderberry pulp. The analytical results show that the MF membrane retained the valuable components in different rate. Significant losses are believed to have occurred after the MF clarification process due to fouling layer resistance, what can be decreased with pectolytic enzymes treatment.

Morphological, biochemical and qualitative changes occurred during growth and development of three pomegranate cultivars were studied at AICRP on Arid Zone Fruits, Department of Horticulture, MPKV, Rahuri. Various changes were determined at 30 days intervals from anthesis till harvest. The pomegranate fruit in all cultivars showed single sigmoid pattern of growth. The size, weight and volume of the fruit of each cultivar increased while the specific gravity increased earlier and then decreased after 90 days in Cv. Bhagwa and after 120 days in Cv. Mridula and Sel-4 to less than one. The elongated oval shape of fruit at the early stage changed to round with prominent suppressions on sides at maturity stage. From those studies, it was revealed that the pomegranate fruits showed colour changes from initial green to orange red and high red at maturity stage and it can be harvested within 150 to 180 days. Among biochemical changes the total soluble solids and TSS: acid ratio increased while the acidity decreased with the advancement in the age of fruit. The total anthocyanin content in arils of pomegranate fruit increased with the advancement in the age of fruit. For qualitative changes, it was found that the percentage of arils and the juice content of arils increased, while the percentage of rind, rind thickness and seed content decreased gradually with the advancement in the age of fruit in each cultivar under study. The percentage of juice content was higher in Mridula at all the stages of maturity than Bhagwa and Sel-4. Seed hardness increased as the fruit matured. Incidence of internal breakdown of arils was noticed earlier in Bhagwa.

Echium Amoenum

Borage flower (Echium amoenum), an annual herb native to the Mediterranean region, is an excellent source of anthocyanins and is widely used in various forms due to its biological activities. In the present study, a choline chloride and glycerol (CHGLY)-based natural deep eutectic solvent (NADES) was applied in order to extract the anthocyanins from borage flowers. The traditional solvents, including water, methanol, and ethanol, were used to evaluate the efficiency of CHGLY. The results showed that CHGLY was highly efficient compared to the traditional solvents, providing the highest amounts of the total anthocyanin content (TAC), total phenolic content (TPC), total flavonoid content (TFC), individual anthocyanins, and antioxidant activity (DPPH radical scavenging (DPPH) and ferric-reducing antioxidant power (FRAP) assays). The most dominant anthocyanin found in studied borage was cyanidin-3-glucoside, followed by cyanin chloride, cyanidin-3-rutinoside, and pelargonidin-3-glucoside. The bioavailability % was 71.86 ± 0.47%, 77.29 ± 0.57%, 80.22 ± 0.65%, and 90.95 ± 1.01% for cyanidin-3-glucoside, cyanidin-3-rutinoside, by pelargonidin-3-glucoside and cyanin chloride, respectively. However, cyanidin-3-glucoside was the anthocyanin compound showing the highest stability (99.11 ± 1.66%) in the gastrointestinal environment. These results suggested that choline chloride and glycerol-based NADES is not only an efficient, eco-friendly solvent for the extraction of anthocyanins but can also be used to increase the bioavailability of anthocyanins.

Fruits from temperate and tropical climates which have high levels of antioxidant compounds are the source of numerous studies concerning the correlation with benefits to human health. The objectives of this study were to quantify the anthocyanins and phenolic compounds and also to measure the antioxidant activity (ferric reducing antioxidant power - FRAP) of blackberries from two varieties grown in southern Brazil ('Brazos' and 'Tupy') at three stages of ripening; unripe, semi-ripe, ripe and their products (pulp and fermented products). During fruit ripening it was observed that weight, size, diameter and sugars increase significantly and acidity decreased significantly. The anthocyanin content ranged from 4.19 (semi-ripe 'Tupy' variety) to 205.75mg 100g-1 (ripe 'Brazos' variety). The highest levels of phenolic compounds were observed for the unripe fruit of both varieties, while antioxidant activity showed no significant difference during the ripening stages. The studied pulp showed a high content of phenolic compounds (ten times higher than that found in the ripe fruits). The anthocyanin content and antioxidant activity did not show the same increase due to the degradation of anthocyanins caused by the heat treatment that was used. The alcoholic fermented beverage made from blackberries remained stable (total phenolic compounds and antioxidant activity) during two years of storage, but the in third year a significant reduction in antioxidant activity was observed. These results can be important for establishing the shelf life of this kind of product made with blackberry

This study aims to investigate the variations in total phenolic content, total anthocyanin content, total flavonoid content and the antioxidant capacity of Roselle extracts in various extraction solvents. Extracts produced using three solvent systems (methanol, ethanol and acetone) at three different concentrations (50, 70 and 90 % (v/v)) were compared roselle calyx extract produced using distilled water. The antioxidant capacities of roselle calyx extracts were evaluated using DPPH free radical-scavenging capacity, ferric reducing antioxidant power (FRAP) and reducing power. The extraction efficiencies of phenolics, anthocyanins and flavonoids from roselle calyx varied considerably. The results showed that at 50 %, ethanol was the appropriate solvent for extraction of flavonoids, which achieved 508.64 mg RE/L and phenolics, which achieved 762.11 mg GAE/L, while at 70 %, methanol was the effective solvent for extracting anthocyanins, which achieved 8.404 mg/L. For antioxidant activity, at 50 % for ethanol, 70 % for methanol, 50 and 70 % for acetone were solvents used to obtain the highest DPPH free radical scavenging activities, ranging from 869.47-927.60 μmol TE/L. Thus, at 50 and 70 % for acetone were determined as solvents which gave extracts with the highest ferric reducing antioxidant power FRAP, ranging from 3493.52–3459.22 μmol TE/L.
