This research attempted to validate novel molecular markers linked to high antioxidant traits using an F2 population and a local Thai rice population. We performed total flavonoid content, total phenolic content (TPC), and ferric reducing antioxidant power (FRAP) assays to assess the antioxidant capacities of rice populations. In the F2 (“Pathum Thani 1”דHawm Mali Daeng”) population, these traits exhibited a quantitative distribution with high heritability (82.7%–98.3%) and high genetic advance (66%–94%). In validation using 10 molecular markers,

Black soybeans are valued for their rich nutritional content and potential health benefits, attributed to their functional components that enhance antioxidant activity. In this study, we evaluate and compare the isoflavone and anthocyanin content, as well as the antioxidant potential, of seven Korean black soybean genotypes. Isoflavone content ranged from 2,032.8 to 3,536.8 µg/g, with Soman displaying the highest levels of both aglycones and glucosides, indicating notable bioactive potential. In terms of anthocyanins, Danheuk had the highest total content (24,080.6 µg/g), while Soman excelled in Pelargonidin-3- glucoside (Pg3glc). Soman also showed superior antioxidant activity across all measures, including total polyphenol, flavonoid content, as well as radical scavenging abilities (ABTS and DPPH). Strong correlations were found between total flavonoid content, total polyphenol content, genistin, total isoflavone content and antioxidant activity, while correlations with total anthocyanins were relatively weaker. These findings reveal significant genetic variability in isoflavone and anthocyanin content among soybean genotypes, with Soman showing particularly high antioxidant potential, suggesting its value for health-related applications and soybean breeding programs.

The faba bean produces medicinally useful phenolic compounds naturally, and is also a good source of food and animal feed. This study quantified the functional compounds and antioxidant activities of five faba bean genotypes selected on the basis of their seed yield and L-dopa content. The highest total tannin content (TTC) and total proanthocyanidin content (TPAC) were observed in the PI252004 genotype and the lowest content in the PI366039 genotype. The total phenolics content (TPC) and total flavonoid content (TFC) of the PI430715 genotype were higher than those of the other genotypes. LC-MS analyses identified 22 different phenolic compounds in the faba bean genotypes. The most abundant proanthocyanidin compounds were prodelphinidin and catechin and the predominant flavonols and flavones were myricetin, quercetin, apigenin, kaempferol, and luteolin-free aglycones or glycosides. The TFC was correlated with ferric-reducing antioxidant power activity (FRAP) (

The present study aimed to determine the contents of five flavonols and two glycoalkaloids as well as the antioxidant activities of leaf ethanol extracts of 50 tomato accessions. The antioxidant activity was assessed using different tests: 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS), 2,2-diphenyl-1-picryl hydrazyl (DPPH), nitric oxide (NO), and total polyphenol content (TPC). Flavonols and glycoalkaloids contents were determined using a high performance liquid chromatography-diode array detector system. Among five flavonols and two glycoalkaloids, naringenin and tomatine were detected in tomato leaves at high concentrations. Of the 50 tomato accessions, IT 229711, IT2365203, and IT 207224 were found to have the highest contents of quercetin, kaempferol, and tomatine, respectively. Leaf extract of IT189949 exhibited the highest relative antioxidant capacity index (RACI). Among the five flavonols, myricetin showed positive correlations with DPPH, ABTS, and NO, while isorhamnetin had positive correlation with DPPH. These results will expand the chemical constitution database and provide information on tomato leaves. They are valuable for the development of functional foods or feed-additives.

Tomato was considered as one of the most widely cultivated vegetable crops in the world. Tomato plant has high antioxidant capacity which can be attributed to the high levels of carotenoids, phenols, vitamins C and E. However, most of tomato plants have been discarded as waste after fruit harvesting. In order to identify genetic resources with high antioxidant level for use in food or as feed additives, we investigated the ABTS, DPPH antioxidant activity and polyphenol content in tomato leaves and stems. A total of 112 tomato accessions were classified into three groups by latitude of their collected countries: 30°~60° North (50 accessions), 0°~30° North (40 accessions), and 0°~30° South (22 accessions). Stem and leaf extracts showed wide variation in ABTS antioxidant activity ranging from 1.6 ± 1.0 to 48.4 ± 6.1 μg Trolox mg−1 dw. The antioxidant activity of DPPH was in the range of 6.3 ± 0.2 to 40.0 ± 0.3 μg ASC mg−1 dw. Total polyphenol content ranged from 6.1 ± 0.2 to 38.9 ± 0.7 μg GAE mg−1 dw. ABTS, DPPH antioxidant activities and polyphenol content in accessions from 30°~60°N latitude were significantly higher (P<0.05) than those from 0°~30°N latitude. ABTS values showed a significant positive correlation (r = 0.700**) with DPPH activity. IT100506 (KOR) and 702959 (UKR) were recommended as potential sources of natural antioxidants due to their highest antioxidant activity among accessions. This study will provide valuable information for tomato breeders in developing and producing functional food or feed additives resources.
