“…Being an important source of natural antioxidants, apples possess one of the highest levels of radical scavenging capacity from the most consumed fruits and vegetables (Chinnici et al, 2004). Similar to our findings (88.55 ±4.25 and 88.49 ±0.73 %, respectively), strong values for AA in the methanolic extracts of Granny Smith (92.71 ±0.33 %) and Golden Delicious (70.73 ±1.49 %) were detected by Asale et al (2021). Moreover, our results showed that values for AA increased in proportion to their TPC.…”

“…The AA of apple cultivars was measured by the DPPH method in which the colour changes from purple DPPH radical to reduced yellow diamagnetic 2-diphenyl-1picryl hydrazine are detected (Asale et al, 2021) (red cv.). A similar trend of the relationship between planting year and ripening period and TPC was also observed in the case of AA.…”

Recently, an increasing interest in fruits and vegetable eating has been noticed in particular through epidemiological and biochemical studies pointing to their health benefits for human health. Specifically, apples (Malus domestica Borkh.) are one of the most frequently consumed fruits. Therefore, the current study aimed to compare the total polyphenols content (TPC) and antioxidant activity (AA) of apple fruits from different columnar apple trees growing in experimental conditions. For this purpose, fruits of 7 apple cultivars obtained from the Botanic Garden (Slovak University of Agriculture, Slovakia; vegetative season 2019/2020) were analysed. Among them, four green-yellow cultivars: Golden Delicious, Granny Smith, Goldcats, Rondo; one green cultivar with red spots: Kordona; one red cultivar: Redcats, and one pink cultivar: Pompink, were used. Method using the Folin-Ciocalteu reagent was applied to quantify TPC, and radical scavenging activity of the samples was measured with 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavengers. Total polyphenols content (mg GAE/g dry weight) ranged from 2.92 ±0.31 (cv. Pompink) to 9.02 ±0.32 (cv. Granny Smith), whereas statistically significant differences (p <0.05) were recorded between all analysed cultivars except for Rondo (5.07 ±0.44) and Kordona (4.18 ±0.35) cultivars as compared to Redcats (4.96 ±1.06) one. As with TPC, the lowest values for AA were observed in the Pompink cultivar (35.03 ±3.49 %) and, conversely, the highest ones in the cultivar Granny Smith (88.55 ±4.25 %). These results suggest that the values for TPC and AA in apple fruits are strongly influenced depending on the apple cultivars. From this aspect, upon achievement of this survey, and employing more samples, it will be possible to create a comprehensive overview of the antioxidant properties of apple fruits with the possibility of their application in the food industry to develop innovative products with added value.

“…Moreover, the chemical composition of apples can be affected by horticultural and cultivar practices. Apples are typically used as a source of phytochemical compounds owing to the high quality and quantity of polyphenols they contain, such as procyanidins, flavanols, phlorizin, chlorogenic acid, anthocyanins, and flavonols [9][10][11][12][13]. In addition to apples being affluent sources of minerals [14] and vitamins [15], they are also a good source of water-soluble carbohydrates, such as fiber pectin, starches, and sugars, which can help decrease blood glucose and cholesterol levels in humans [10,13].…”

Subcritical water, which is an effective solvent for polar and nonpolar substances, has been used to extract numerous natural ingredients. In this study, subcritical water was used to extract bioactive substances from apple peel in a batch process in the temperature range of 100–175 °C for 5–60 min. The Fourier-transform infrared spectroscopy results revealed that phenolic compounds were released from apple peel in the aforementioned temperature range. The ultraviolet–visible spectra of the liquid products at 280 nm revealed the high content of phenolic compounds in the extracts. The high-performance liquid chromatography results demonstrated that the yield of procyanidin B2 was approximately 2.28 mg/g of dried apple peel when extraction was performed at 150 °C for 15 min.
