“…Increasing the biomass and sugar yield potential of sorghum is one of the most important targets of breeding programs [2,3]. However, despite its high importance to the bioindustry, sorghum variety development has been biased toward improving seed yield and nutrient value [9]. Hence, there is a need for research focused on biomass traits and the development of sorghum varieties suitable for utilization as a bio-industrial material.…”

Sorghum (Sorghum bicolor L.) is a promising biomass crop with high yields of cellulose, hemicellulose, and lignin. Sorghum biomass has emerged as an eco-friendly industrial material useful for producing biofuels and bioplastics. This study conducted genotyping-by-sequencing (GBS)-based genome-wide association studies (GWAS) to establish the genetic basis of traits associated with biomass. Specifically, the researchers evaluated agronomic traits and phenolic compounds using 96 sorghum genotypes. Six phenolic compounds, luteolinidin diglucoside, luteolin glucoside, apigeninidin glucoside, luteolinidin, apigeninidin, and 5-O-Me luteolinidin, were found to be the major phenolic compounds in all genotypes. Out of our six detected phenolic compounds (luteolinidin diglucoside, luteolin glucoside, apigeninidin glucoside, luteolinidin, apigeninidin, and 5-O-Me luteolinidin), luteolinidin was the major phenolic compound in all genotypes. Next, a GWAS analysis was performed to confirm significant associations between 192,040 filtered single-nucleotide polymorphisms (SNPs) and biomass-related traits. The study identified 40 SNPs on 10 chromosomes that were significantly associated with heading date (4 SNPs), plant height (3 SNPs), dry yield (2 SNPs), and phenolic compounds (31 SNPs). The GWAS analysis showed that SbRio.10G099600 (FUT1) was associated with heading date, SbRio.09G149200 with plant height, SbRio.06G211400 (MAFB) with dry yield, SbRio.04G259800 (PDHA1) with total phenolic content and luteolinidin diglucoside, and SbRio.02G343600 (LeETR4) with total phenolic content and luteolinidin, suggesting that these genes could play key roles in sorghum. These findings demonstrate the potential value of sorghum as a biomass resource and the potential for selecting sorghum genotypes with reduced phenolic contents for use in the bioindustry.

“…Tyrosinase inhibitory activity is not only clinically useful because of its ability to treat skin cancer and skin diseases caused by melanin pigmentation, but is also particularly important in the cosmetic industry because of its ability to depigment and whiten the skin after sunburn [42]. The tyrosinase inhibitory activity of the ethanol extract of each sorghum variety was measured at 61.64-62.16% of Dongan Mega [43]. The results of their study are lower than our results, which showed that the tyrosinase inhibitory activity of Uzbekistan sorghum seed extract was 79.20±4.15%.…”

The current study evaluated the presence and concentration of health-promoting phenolic antioxidants in sorghum seed accessions from seven regions in three different countries (Uzbekistan, Myanmar, and the United States). The free radical scavenging activity using the 2,2-diphenyl-1-picrylhydrazyl assay was 13.10±2.37 μg/mL in the Uzbekistan sorghum seed extracts, demonstrating the highest antioxidant activity. Additionally, the total phenol content was the highest in the Uzbekistan sorghum seed extracts [157.87±4.04 mg GAE/g (gallic acid equivalents per gram)]. The total flavonoid content was 12.69±0.72 mg QE/g (quercetin equivalents per gram) and represents the highest value in the Myanmar collection. The Uzbekistan collection demonstrated the greatest potential for whitening activity, with the tyrosinase inhibition rate of 79.20±4.15%. The wrinkle improvement function using elastase also showed the highest anti-aging activity of 55.85±4.78% in the same seed extract. The Uzbekistan seed extract had the highest NO production inhibitory activity of 144.35±4.55%. We conclude from these results that the Uzbekistan sorghum seed has excellent antioxidant activity, content of various functional ingredients, and anti-inflammatory activity.

In this study, changes in bioactive compound contents and the in vitro biological activity of mixed grains, including oats, sorghum, finger millet, adzuki bean, and proso millet, with eight different blending ratios were investigated. The total phenolic compounds and flavonoid contents ranged from 14.43–16.53 mg gallic acid equivalent/g extract and 1.22–5.37 mg catechin equivalent/g extract, respectively, depending on the blending ratio. The DI-8 blend (30% oats, 30% sorghum, 15% finger millet, 15% adzuki bean, and 10% proso millet) exhibited relatively higher antioxidant and anti-diabetic effects than other blending samples. The levels of twelve amino acids and eight organic acids in the grain mixes were measured. Among the twenty metabolites, malonic acid, asparagine, oxalic acid, tartaric acid, and proline were identified as key metabolites across the blending samples. Moreover, the levels of lactic acid, oxalic acid, and malonic acid, which are positively correlated with α-glucosidase inhibition activity, were considerably higher in the DI-blending samples. The results of this study suggest that the DI-8 blend could be used as a functional ingredient as it has several bioactive compounds and biological activities, including anti-diabetic activity.
