Abstract
Chokeberry (Aronia Medik.) is a non-traditional fruit plant known as a rich source of biologically active compounds and inhibits the numerous biological activities. We compared the antioxidant activity and phenolic compounds of fruits between widely cultivated Aronia mitschurinii (AM-TCH, from Tchekhov district; AM-D, from Dmitrov district; AM-OZ, from Orekhovo-Zuevsky district of Moscow region, Russia) and introduced North American Aronia species (Aronia arbutifolia (AA-M), A. melanocarpa (AML-M), A. × prunifolia (AP-M), which have not been planted yet in the arboretum of Main Botanical Garden of the Russian Academy of Sciences (Moscow). Studying samples were collected in their secondary distribution range. Ethanolic extracts were determined for antioxidant capacity (antioxidant activity by DPPH and phosphomolybdenum methods, the total content of polyphenols, flavonoids, phenolic acids) and measured spectrophotometrically. As standards were used Trolox (TE) for antioxidant activities, gallic acid (GAE) for polyphenol content, quercetin (QE) for flavonoid content, caffeic acid (CAE) for phenolic acid content. The antioxidant activity by DPPH method in ethanol extracts of investigated plants was from 6.96 (AM-D) to 8.89 (AM-OZ) mg TE.g-1 DW. Reducing the power of investigated extracts exhibited activity from 151.47 (AM-OZ) to 297.8 (AA-M) mg TE.g-1 DW. The content of polyphenol compounds determined from 25.98 (AM-TCH) to 54.39 (AA-M) mg GAE.g-1 DW, phenolic acids content was from 7.76 (AP-M) to 11.87 (AM-D) mg CAE.g-1 DW and the content of flavonoids detected from 8.12 (AM-OZ) to 16.62 (AM-D) mg QE.-1 DW. Obtained data showed a strong correlation between the content of polyphenol compounds and reducing the power of extracts (r = 0.700), between flavonoids and phenolic acids (r = 0.771) and also between phenolic acids and reducing power (r = 0.753) in Aronia ethanol extracts. Fruits of investigated species of Aronia can be propagated as a source of polyphenol compounds with antioxidant activity and obtained results may use for farther pharmacological study.
Highlights
The last studies demonstrated that fruit plants are rich in antioxidants and their use can promote human health (Widén et al, 2012)
We investigated fruits of plants of Aronia arbutifolia (L.) Pers. (AA-M), A. melanocarpa (Michx.) (AML-M), Aronia × prunifolia (Marshall) Rehder (AP-M) in the arboretum of Main Botanical Garden of the Russian Academy of Sciences (Moscow, Russia), which were brought from the USA in the 1980s
Numerous biologically active compounds act as powerful antioxidants, among which different groups of polyphenol compounds that are determined in fruits and berries (Szopa et al, 2017; Aly, Maraei and El-Leel, 2019; Rodriguez-Werner, Winterhalter and Esatbeyoglu, 2019)
Summary
The last studies demonstrated that fruit plants are rich in antioxidants and their use can promote human health (Widén et al, 2012). K. Skvortsov and Maitul are one of the most famous sources of food polyphenols and antioxidants, its juice has long been used in clinical practice. According to a later nomenclature (Hardin, 1973), the genus Aronia consists of three species: A. arbutifolia (L.) Rers., A. melanocarpa (Michx.) and their hybrid A. There, by the method of "screening in three generations", a man-made A. mitschurinii was born (Vinogradova and Kuklina, 2014). It is still unclear whether this taxon arose as a result of macro mutation, or is it a hybrid between
