Comparison of Phytochemicals and Antioxidant Activities of Berries Cultivated in Korea: Identification of Phenolic Compounds in Aronia by HPLC/Q-TOF MS

Abstract

Aronia, blueberry, Korean raspberry, blackberry, mulberry, and red raspberry fruits cultivated in Korea were evaluated for total phenol content (TPC), total flavonoid content (TFC), total anthocyanin, and ascorbic acid content. All berries were assayed for antioxidant activities determined as 2,2-diphenyl-1-picrylhydrazyl free radical scavenging activity, 2,2'-azino-bis(3-ethylbenzothiazoline)-6 sulphonic acid free radical scavenging activity, and ferric reducing antioxidant power. Individual phenolic compounds in aronia were also identified using high-performance liquid chromatography/ quadrupole-time of flight mass spectrometry. TPC, TFC, total anthocyanin, and ascorbic acid contents of the fruit samples ranged from 17.05 to 135.55 mg of gallic acid equivalent/g dry weight (dw), 1.0 to 8.59 mg of rutin equivalent/g dw, 2.55 to 24.43 mg of cyanidin-3-O-glucoside equivalent/g dw, and 3.14 to 19.45 mg of ascorbic acid equivalent/g dw, respectively. Aronia and Korean raspberry showed the highest TPC, TFC, and total anthocyanin while red raspberry had the highest ascorbic acid content. Antioxidant activities showed positive correlations to phenolic and anthocyanin contents suggesting antioxidant activity of berry samples is due to these compounds. Aronia had the highest antioxidant value among fruits.

Novel inhibitory effect of black chokeberry (Aronia melanocarpa) from selected eight berries extracts on advanced glycation end-products formation and corresponding mechanism study

“…The total antioxidant capacity (TAC) levels of berry extracts ranged from 9.85 ± 0.33 to 168.83 ± 1.07 mg C3G equivalents/g DW. Blueberry exhibited the highest TAC value (168.83 ± 1.07 mg C3G equivalents/g DW), followed by black chokeberry (111.58 ± 3.33 mg C3G equivalents/g DW), which is consistent with values reported in a previous study ( Kim, Han, Kim, Kim, & Kim, 2021 ). Furthermore, our study found that black chokeberry had the highest TPAC among all the tested berries, with a content of 42.54 ± 6.94 mg PCB2/g DW, almost four times that of blueberry.…”

Phytochemical Screening of Methanolic Extract of Urtica dioica L.: Antioxidant and Antimicrobial Power for Food Safety

“…These natural compounds have low health toxicity and biodegradability and therefore are safe for the environment (Habeeb et al, 2022). Plant bioactive compounds present an amazing range of structural diversity and biological activities, such as pharmaceuticals and alternatives to agricultural chemicals (Kim et al,2021). Algeria has an important heritage of endemic medicinal and aromatic plants (Ayari-Guentri et al,2022).…”

Physical, mechanical, and antioxidant properties of alginate/pectin edible films with incorporated chokeberry and wild thyme extracts

“…The dark red colour of the A. melanocarpa extract is due to the high content of anthocyanins (1 746.7 mg cyd eq•L -1 ). A. melanocarpa is one of the fruits with the highest content of polyphenols and anthocyanins (Kim et al 2021). In the present work, extraction of wet pomace, remaining after separation of the juice, was carried out.…”
