In this study, 21 synthetic hexaploid wheat samples were analyzed and compared for phenolic content (the Folin–Ciocalteu method), phenolic compositions, and antioxidant activity (DPPH, ABTS, and CUPRAC). The aim of the study was to determine the phenolic content and antioxidant activity of synthetic wheat lines developed from Ae. Tauschii, which has a wide genetic diversity, to be used in breeding programs for developing new varieties with better nutritional properties. Bound, free, and total phenolic contents (TPCs) of wheat samples were determined as 145.38–258.55 mg GAE/100 g wheat, 188.19–369.38 mg GAE/100 g wheat, and 333.58–576.93 mg GAE/100 g wheat, respectively. Phenolic compositions were detected by the HPLC system. Gallic acid was found in the highest concentrations in free fractions, whereas gallic, p-coumaric acid, and chlorogenic acid were generally found in the highest concentrations in bound fractions of the synthetic hexaploid wheat samples. The antioxidant activities (AA%) of the wheat samples were evaluated by the DPPH assay. AA% in the free extracts of the synthetic red wheat samples ranged from 33.0% to 40.5%, and AA% values in the bound extracts of the synthetic hexaploid wheat samples varied between 34.4% and 50.6%. ABTS and CUPRAC analyses were also used to measure antioxidant activities. The ABTS values of the free and bound extracts and total ABTS values of the synthetic wheat samples ranged from 27.31 to 123.18, 61.65 to 263.23, and 93.94 to 308.07 mg TE/100 g, respectively. The corresponding CUPRAC values of the synthetic wheats were between 25.78–160.94, 75.35–308.13, and 107.51–364.79 mg TE/100 g. This study revealed that synthetic hexaploid wheat samples are valuable resources for breeding programs for developing new wheat varieties with higher concentrations and better compositions of health-beneficial phytochemicals. The samples w1 (Ukr.-Od. 1530.94/Ae. squarrosa (629)), w18 (Ukr.-Od. 1530.94/Ae. squarrosa (1027)), and w20 (Ukr.-Od. 1530.94/Ae. squarrosa (392)) can be used as a genetic resource in breeding programs to enhance the nutritional quality of wheat.

“…Полученные нами результаты анализа состава фенольных соединений листьев A. sellowiana согласуются с ранее проведенными исследованиями, где авторы сообщают о присутствии 15 соединений, в том числе флавоноидов и эллаговой кислоты [13]. По другим данным, листья A. sellowiana также содержат катехин, кверцетин, галловую и эллаговую кислоты и могут быть использованы в качестве потенциального источника этих соединений [14]. Проведенный анализ содержания фенольных соединений в листьях A. sellowiana показал, что количество гидролизуемых таннинов в листьях A. sellowiana составляло 44,28 мг/г или 90 % от общего содержания фенольных соединений.…”

Introduction. Acca sellowiana, or feijoa belongs to the Myrtaceae family and it is an evergreen shrub or small tree 4–6 meters high. The phytochemical composition has been most thoroughly studied in the fruits of A. sellowiana. It has been shown that feijoa is rich in phenolic acids, hydrolysable and condensed tannins, steroidal saponins, and flavonoids. Hydrolysable tannins are known to have high biological activity.Aim. To study the composition and content of hydrolysable tannins in the leaves of A. sellowiana.Materials and methods. Ultra-high performance liquid chromatography coupled with diode array detection and mass spectrometry.Results and discussion. The results obtained showed the presence of 22 phenolic compounds in the extract of the A. sellowiana leaves. They have been classified as flavan-3-ols, flavonoids and hydrolysable tannins. Two compounds could not be identified. The total content of hydrolysable tannins was 44,28 mg/g (90 % of the total phenolic content). At the same time, ellagitannins were the main phenolic compounds of the extract (40,47 mg/g), while the amount of galloyl-glucose was only 3,81 mg/g.Conclusions. Composition and content of hydrolysable tannins in the leaves of A. sellowiana introduced in the greenhouse of VILAR have been studied. The leaves accumulate mainly monomeric ellagitannins represented 92 % of the total content of hydrolysable tannins. The data obtained indicate that the leaves of A. sellowiana can be used as a raw material for obtaining extracts with a high content of ellagitannins and developing drugs based on them.

Botanical beverages are the latest trend in the health drink industry. Natural plant extracts bring many health benefits. The objective of this research was to investigate changes in the biological activity of sapodilla (Manilkara zapota) leaf powder production and extraction for functional food applications. The first investigation determined the effect of different leaf ages. The leaves were dried using a hot air oven. After leaf powder extraction, phytochemical content, antioxidant capacity and antihyperglycemic activities were monitored. Optimal condition for sapodilla leaf powder production was drying mature leaves at 55 °C, giving total phenolic content (TPC) at 36.10 mg GAE/g extract and IC 50 values of α-amylase and α-glucosidase 0.054 and 0.001 mg/mL, respectively. Extraction of sapodilla leaf powder using 50% acetone solvent gave TPC 260.54 mg GAE/g extract and IC 50 of α-amylase and α-glucosidase 0.004 and 0.00 mg/mL, respectively with glucose uptake into HepG2 cells increased from 290% to 710%. Using sapodilla leaves to make botanical beverages provided antioxidant benefits and inhibited digestion enzymes.
