Biological And Medical Applications

Currently, there have been lots of interests in phytochemicals as bioactive components. The roles of fruit, vegetables, and red pigments in preventing diseases have been partly accredited to the antioxidant properties of their constituent polyphenols, flavonoid, anthocyanins, and etc. Biochemistry parameters including the relative levels of antioxidant activity, total phenolic content, total flavonoid, total anthocyanin, soluble and insoluble sugar content of Ribes khorasanicum, have been calculated in this project. The total anthocyanin content of the investigated Ribes khorasanicum measured to be 62.9 mg/g in dry weight, while displaying high levels when compared to other components, which indicates that the anthocyanin content was the predominant antioxidant components in the investigated plant. This particular plant has the potential to serve as the important source of antioxidant that can be utilized in different biological and medical applications.

Comprehensive Comparison

Commercial blueberry production has been a viable industry throughout the world for 95 years; because of blueberry is a good source of antioxidant. Blueberries are especially rich in anthocyanin, a flavonoid with potent antioxidant capacity. The aim of this study was to compare the phenolic quantities, antioxidant activities, anthocyanin, sugar and phenolic compounds of blueberries produced in Turkey with those of similar blueberry varieties produced around the world. As a result of the conducted analysis, the total phenolic content (TPC) amount found in the berries was 77.26-215.12 mg GAE/100 g, the total flavonoid content (TFC) was 30.44-91.69 mg QE/100 g and the total anthocyanin content (TAC) was 43.03-295.06 mg c3-GE/100 g. Examining the antioxidant activities of the berries, DPPH between 1.10-5.65 mg/ml, FRAP between 454.93-36832.96 µmol troloks/100 g, β-Carotene between 40.66-86.48%. It was determined that the natural berries contained much more phenolic compounds and higher antioxidant activity than that of the cultivars The result of HPLC analysis, chlorogenic acid is determined to be the dominant compound in all berries. Furthermore, fructose and glucose are found in all fruits in different quantities while sucrose is found in certain varieties of berries as well. At the end of the performed study the data indicate that wild and cultivars of blueberries are rich sources of antioxidants for local as well international industries importing this fruit for food processing and enormous products.

Wild Edible Fruits

Turkey has great ecological, topological and geographical diversity within the country and this diversity has contributed not only to a high genetic diversity, but has also allowed the successful introduction and cultivation of a great number of fruit tree taxa. Turkey is also known to have a great richness of wild edible fruits with regard to variety and biological diversity. Rowanberry or mountain ash (Sorbus aucuparia L.) is one of the wild edible fruits naturally found most parts of Turkey. Present study describes morphological (tree growth habit, fruit color) and biochemical fruit traits (vitamin C, organic acids, specific sugars, total phenolic content, total anthocyanin content, total antioxidant capacity) of 17 seed propagated rowanberry genotypes. We found significant differences among almost all studied parameters. The genotypes had diverse L, chroma and hue values, which found between 28.76-42.38%; 24.11-29.45% and 33.13-42.66%, respectively. Among sugars and organic acids, Glucose and Malic acid were dominant in rowanberry fruits, respectively. Total phenolic content, total anthocyanin content, vitamin C and antioxidant activity varied from 123-189 mg GAE per 100 g, 18-57 mg per 100 g, 25.6-40.2 mg per 100 g and 3.36-6.92 mM trolox equivalent per 100 g of fresh weight (FW) basis. Results suggest using rowanberry fruits in production of functional foods with high biologically active properties.

Theobjective of thisstudyis to investigate the phenotypic and biochemicalparameters of selectedsweet cherry (Prunus avium) from middle region of Morocco. Themain biochemical composition, contentsof total polyphenols, total flavonoids, total anthocyanins and antioxidant activity, were measured in the fruits of four sweet cherry cultivars (ʻBurlat’, ʻVan’, ʻNapoleon’andʻCerisette’) grown in two locations (“Laanoceur”and “Toufselt”) in the MiddleAtlas. The free radical scavenging activity was evaluated spectrophotometrically using 1,1‒diphenyl‒2‒picrylhydrazine (DPPH)and ABTS assay.The fruit weight, and pulppercentagewerestudied and found to range between 237–329 g, 38.14–42.22%, 39.21–44.36g, and 52.27–57.48%, respectively.The total phenolic and total anthocyanin content rangedfrom305.99 and 306.67 mg EqGal/100g D.W, total flavonoid contents were within the range of 481.73-517.67 mgeqRE/100g D.W, and total anthocyanin contents were between 1.09 and 2.89 mg Eqcyanidin 3-glucoside/100g D.W. Antioxidant activity ranged from 17.18 to 18.11 mg EqTrolox/100g D.W for DPPH assayand from 27.97 to 29.60 mg EqTrolox/100f D.W for ABTS method.The highest values of total anthocyanin content and antioxidant activity (DPPH) were recorded in ʻBurlat’. The highest value of total flavonoid content was found in ʻCerisette’. Cherries from “Laanoceur”and “Toufselt” locations are characterized by similar biochemical composition and antioxidant activity, except for total anthocyanin content that shows slightly elevated values in “Laanoceur”. The close correlation between total phenolic contents and antioxidant activities (r2=0.73) show that antioxidant activity of cherry fruit depends on total polyphenols.

The astringent sensation of wines is attributable to the composition and concentration of phenolic compounds. However, in many cases, experimental results have shown a gap in relation to sensory astringency. The aim of the present study was to evaluate the relationships between the experimental evidence of astringent attributes and perceived astringency. To this end, the concentrations of phenolic compounds, namely, the total phenolic content (TPC), the polymeric tannin content (PTC), the proanthocyanidin content (PAC) and the total anthocyanin content (TAC), in wines made from a variety of grape breeding lines were estimated and their relationships to perceived astringency were evaluated. The TPC and the PTC showed strong positive correlations with perceived astringency. In contrast, the PAC showed a moderate correlation with perceived astringency, which was lower than that shown by the PTC despite their similar phenolic compositions. Unlike the other attributes, the TAC showed a weak correlation with perceived astringency. We concluded that the TPC and the PTC showed good correlations with perceived astringency and could be used as an index for predicting the astringency of wines.

Dietary antioxidants may have a role in preventing some of the chronic diseases in humans resulting from free radical oxidation of lipids and other cellular components. Blueberries (Vaccinium L. sp.) are considered one of the best fresh fruit sources of antioxidants, and there is the potential to increase the antioxidant activity further through breeding. Thus, the variability of fruit antioxidant activity (AA) was examined among a set of 16 highbush and interspecific hybrid cultivars grown at locations in Minnesota (MN), Michigan (MI), and Oregon (OR) over 2 years (1998 and 1999) to determine effects of genotype, year, and location. Nine cultivars were common to all three locations in both years. Antioxidant activity, total phenolic content (TPH), and total anthocyanin content (ACY), were determined in triplicate samples from each genotype. Cultivars differed significantly (P ≤ 0.05) in AA, TPH, and ACY both within and over locations. The single location mean AA for all cultivars changed significantly between the 2 years in OR and in MI, while the single location mean for TPH differed between the 2 years in MN and MI. Changes in cultivar rank were significant for AA, TPH, and ACY between years within each location. Significant changes in rank for TPH and ACY were also noted between pairs of locations as well. Pearson's correlation for AA (based on cultivar means) appeared highest between MN and OR (r = 0.90) and MN and MI (r = 0.69) in 1998; correlations between locations for the combined years were 0.74 for MN and OR, 0.55 for MN and MI and 0.45 for MI and OR. For the group of nine cultivars, AA correlated well with TPH within each location, with r ranging from 0.67 to 0.95 for data from individual and combined years. Correlation of AA with ACY at each location was lower than that for AA with TPH, in both individual and combined years. This study demonstrates significant genotype× environment interaction for AA in blueberry.

Thornless Blackberry

Fruit and leaves from different cultivars of thornless blackberry (Rubus sp.), red raspberry (Rubus idaeus L.), black raspberry (Rubus occidentalis L.), and strawberry (Fragaria × ananassa D.) plants were analyzed for total antioxidant capacity (oxygen radical absorbance capacity, ORAC) and total phenolic content. In addition, fruit were analyzed for total anthocyanin content. Compared to fruit, leaves were found to have higher ORAC values. In fruit, ORAC values ranged from 7.8 to 33.7 μmol Trolox equivalents (TE)/g of fresh berries, while in leaves, ORAC values ranged from 20.8 to 45.6 μmol TE/g of fresh leaves. Fruit harvested at different stages of maturity were analyzed in blackberries, raspberries, and strawberries. Blackberries and strawberries had their highest ORAC values during the green stages, while raspberries generally had the highest ORAC activity at the ripe stage (with exception of cv. Jewel, a black raspberry). Total anthocyanin content increased with maturity for all three fruit. There was a linear correlation existed between total phenolic content and ORAC activity for fruit and leaves. For ripe berries, there was also a linear relationship between ORAC values and anthocyanin content. Of the ripe fruit and leaves tested, raspberry plants appeared to be the richest source for antioxidants.
