Fresh fruits and jam of Sorbus domestica L. and Sorbus intermedia (Ehrh.) Pers.: Phenolic profiles, antioxidant action and antimicrobial activity

Abstract

A detailed examination of the phenolic profile, ascorbic acid content and antioxidant and antimicrobial capacities of extracts and jams of the fruits of two traditionally used Sorbus species, viz., S. domestica and S. intermedia, was carried out in the present study. Use of the LC-MS/MS technique revealed the presence and content of 44 phenolics, the most dominant compounds being amentoflavone in S. domestica and chlorogenic acid in S. intermedia extracts. Jam of both species showed the highest content of аscorbic acid. In comparison with BHT (butylated hydroxytoluene) and PG (propyl gallate) antioxidant standards, both Sorbus species exhibited moderate antioxidant action. Some extracts of S. domestica and S. intermedia inhibited the growth of two clinically relevant bacterial strains. The presented results support the belief that Sorbus fruits are food with health-promoting properties. C ilj rada predstavljao je detaljno ispitivanje fenolnog profila, sadržaja vitamina C, antioksidantne i antimikrobne aktivnosti ekstrakata i pekmeza plodova dve tradicionalno korišćene vrste roda Sorbus: S. domestica i S. intermedia. Pristustvo i sadržaj 44 fenolna jedinjenja urađena je pomoću LC-MS/MS, gde je dominantno jedinjenje bio amentoflavon u ekstraktima S. domestica, odnosno hlorogenska kiselina u ekstraktima S. intermedia. Najveći sadržaj vitamina C detektovan je u pekmezima. U poređenju sa standardnim antioksidantima BHT i PG, obe vrste roda Sorbus ispoljile su umerenu antioksidantnu aktivnost. Pojedini ekstrakti S. domestica i S. intermedia pokazali su aktivnost u inhibiranju rasta dva klinički releventna bakterijska patogena. Prezentovani rezultati podržavaju potencijal voća vrsta roda Sorbus kao hrane sa pozitivnim dejstvom na zdravlje.

Nutrient Constituents, Bioactive Phytochemicals, and Antioxidant Properties of Service Tree (Sorbus domestica L.) Fruits

“…Results also showed that quercetin-3- β -glucoside was found in the highest amount, while the other flavonoids appeared to be minor constituents in service tree fruits. This result confirmed the findings of previous studies that 3- O -glycosylated quercetin was more prevalent among other flavonoids [ 7 , 12 ]. Furthermore, it can be seen that neochlorogenic and 3,4-dihydroxybenzoic acids were major constituents (97%) among phenolic acids detected, whereas ellagic and ferulic acids were found in small amounts.…”

“…A thorough review of current scientific knowledge of the service tree revealed that scientists have conducted investigations, mainly into different ecological, morphological, and genetic aspects [ 1 , 2 , 3 , 4 , 5 ]. Unfortunately, however, few studies are focused upon the chemical composition and nutritional value of the service tree fruits [ 4 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. A very minor part of the reports draws attention to the presence and accumulation of some minerals [ 6 , 13 ].…”

“…A very minor part of the reports draws attention to the presence and accumulation of some minerals [ 6 , 13 ]. The other reports note evidence that fruits and their extracts are a rich source of phenolic compounds, and they possess a wide range of benefits including anti-inflammatory, antidiabetic, antimicrobial, and antioxidant [ 7 , 8 , 10 , 14 ]. Furthermore, in a series of articles, a team of scientists has reached a deep understanding of the phenolic composition of fruits at different maturity stages [ 9 , 11 , 12 ].…”

Effect of the duty cycle of the ultrasonic processor on the efficiency of extraction of phenolic compounds from Sorbus intermedia

“…In the present study, the rutin levels ranged from 37.22 to 173.76 µg/g DM. The concentrations of rutin in water and methanol extracts of Sorbus aucuparia were 82.3 and 80.4 mg/g DW, respectively 48 . Šavikin et al 51 indicated that rutin content ranged from 138.4 to 892.0 μg/g DW in Sorbus aria and 40.1 to 598.3 μg/g DW in Sorbus aucuparia extracts.…”

“…There are very little data in the literature with which our results could be easily compared, given the methods of extraction, analysis, units and plant species. Mrkonjić et al 48 determined DPPH and FRAP values in methanolic extracts from the fruits of Sorbus intermedia , but they express their results in ascorbic acid equivalents. They obtained the following data: DPPH 0.20 ± 0.01 mg of AAEc/g DW and FRAP 4.47 ± 0.39 mg of AAEc/g DW.…”
