Evaluation of chemical constituents and antioxidant activity of sweet cherry (Prunus avium L.) cultivars

Abstract

This research was undertaken to evaluate the sugars, organic acids, phenolic compositions and antioxidant capacities of sweet cherry cultivars (Van, Noir de Guben, Larian and 0-900 Ziraat) grown in Turkey. High-performance liquid chromatographic methods were used to identify and quantify four sugars (sucrose, glucose, fructose and sorbitol) and four organic acids (malic, citric, shikimic, and fumaric acid). The major organic acid was found as malic acid (8.54-10.02 g kg )1 of FW). With regard to sugars, glucose was present in the largest amounts (44.71-48.31 g kg )1 of FW) for sweet cherry cultivars. The sum of sugars ranged from 103.87 (Larian) to 113.13 g kg )1 of FW (0-900 Ziraat) and that of organic acids from 12.01 (0-900 Ziraat) to 14.17 g kg )1 of FW (Noir de Guben). A total of eleven phenolic compounds were identified and quantified in sweet cherry cultivars, including hydroxycinnamic acids (3), anthocyanins (5), flavan-3-ols (2) and flavonol (1) compounds. Total phenolic contents ranged from 88.72 (Van) to 239.54 (Noir de Guben) mg ⁄ 100 g of FW, while antioxidant activities ranged from 2.02 to 7.75 lm Trolox equivalents g )1 of FW.

Physicochemical Characteristics, Antioxidant Activity, Organic Acid and Sugar Contents of 12 Sweet Cherry (Prunus Avium L.) Cultivars Grown in Turkey

“…These variations may be due to differences in maturation stages (Serradilla and others ) and cultivars (Usenik and others ). These findings are close to those of results of Usenik and others () and Liu and others (); however, they are lower than the results of Kim and others (), Kelebek and Selli (), and Serra and others ().…”

“…The darker fruits showed higher antioxidant activity levels and the same results were observed by Gonzalez‐Gomez and others () and Liu and others (). The data obtained were also comparable to the results of Kelebek and Selli (). DPPH • , faster and more reproducible method and the values changed significantly among sweet cherry cultivars ( P < 0.05).…”

“…In general, the darker fruits have higher levels of antioxidant activity than lighter ones due to phenolics, thiols, and so on (Re and others ; Usenik and others ). The same results were obtained by Kelebek and Selli () for 4 sweet cherry cultivars grown in Turkey and Usenik and others () for 13 sweet cherry cultivars grown in Slovenia. The highest values of FRAP were measured in Durona di Cesena (1.61 mg TE/g FW), followed by Vista (1.06 mg/TE g FW) and Belge (1.03 mg/TE g FW).…”

“…The 5 cultivars including Belge, Bing, Durona di Cesena, Lambert and Merton Late contained 78 to 115 mg GAE/100 g FW and while the rests included approximately 58 to 70 mg GAE/100 g FW as illustrated in Table . In Turkey, Kelebek and Selli () pointed out that 4 sweet cherry cultivars (Van, Noir de Guben, Larian and 0–900 Ziraat) contained 88.7 to 239.5 mg GAE/100 g FW; however, these values are the sum of individual phenolic compounds in the fruits. Our results are consistent with the previous studies (Kim and others ; Vursavuş and others ; Usenik and others ).…”

High pressure and thermal pasteurization effects on sweet cherry juice microbiological stability and physicochemical properties

“…It is rich in nutrients and bioactive compounds, having relatively low caloric content while containing substantial amounts of anthocyanins, polyphenols and high antioxidant activity. [2][3][4] The sweet cherry composition has been extensively studied due to its impact on human health, since it is claimed to have several potential health benefits in relation to cancer, diabetes, inflammatory and cardiovascular diseases. [1,5,6] Since sweet cherry is a relatively seasonal and perishable fruit, is not always available to the consumer as a fresh fruit, [7] but it can be processed into juice, meeting the consumer demand for drinks with potential health benefits.…”
