“…Furthermore, in black sweet maize from China, despite being a quite different variety, the total anthocyanin content was similar, but the main compounds were pelargonidin derivatives, followed by cyanidin and then peonidin derivatives. 44 The differences in the major anthocyanins among the mentioned studies suggest that each purple maize variety had its own dominant anthocyanin type. Moreover, the dominant anthocyanins were related to plant pigment; in a study, the authors showed that while the predominant anthocyanins in blue-aleurone and purple-pericarp maize were cyanidin-based glucosides, pelargonidin-based glucosides were the dominant in reddish-purplepericarp and cherry-aleurone accessions.…”

The present work aimed to characterize the phenolic and antioxidant content of the Argentinian purple maize "Moragro" cultivar. Additionally, the INFOGEST simulated in vitro digestion model was used to establish the effect of digestion on bioactive compounds. Finally, digestion samples were used to treat Caco-2 cells in the transwell model to better understand their bioavailability. Twenty-six phenolic compounds were found in purple maize cv. "Moragro", 15 nonanthocyanins and 11 anthocyanins. Several compounds were identified in maize for the first time, such as pyrogallol, citric acid, gallic acid, kaempferol 3-(6″-ferulylglucoside), and kaempferol 3-glucuronide. Anthocyanins accounted for 24.9% of total polyphenols, with the predominant anthocyanin being cyanidin-3-(6″ malonylglucoside). Catechin-(4,8)-cyanidin-3,5-diglucoside and catechin-(4,8)-cyanidin-3malonylglucoside-5-glucoside were detected as characteristics of this American maize variety. Total polyphenol content (TPC; by the Folin−Ciocalteu method), HPLC-DAD/MSMS, and antioxidant activity [by DPPH and ferric-reducing antioxidant power (FRAP)] were evaluated throughout in vitro digestion. TPC, DPPH, and FRAP results were 2.71 mg gallic acid equivalents (GAE)/ g, 24 μmol Trolox equiv/g, and 22 μmol Trolox eq/g, respectively. The in vitro digestion process did not cause significant differences in TPC. However, the antioxidant activity was significantly decreased. Moreover, the bioavailability of anthocyanins was studied, showing that a small fraction of polyphenols in their intact form was conserved at the end of digestion. Finally, a protective effect of digested maize polyphenols was observed in the Caco-2 cell viability. The results suggest that "Moragro" purple maize is a good source of bioavailable anthocyanins in the diet and an interesting source of this group of compounds for the food industry.

“…O. sativa , as the staple food and model organism, contains flavonoids such as flavone O-glycosides, acylated flavonoid O-glycosides, tricin-O-glycosides and flavonol-O-glycosides ( Yan et al, 2019 ). The major flavonoid in extracts of Zea mays silk is luteolin, followed by apigenin and formononetin ( Hu et al, 2020 ). In this study, the flavonoid content was the highest at the DAF5 stage (16.6 mg/g) during fruit developmental stages and continuously decreased from DAF5 to DAF30.…”

Astragalus membranaceus, as an important medicinal plant, are an excellent source of flavonoids. Flavonoid compounds in A. membranaceus have been widely used in medicine and supplement, but known of the molecular mechanism of flavonoid biosynthesis is still very few. Here, we analyzed the association between flavonoid content and gene expression pattern during six different fruit developmental stages. Sixteen gene expression trends were significantly identified, involving 8,218 genes. The gene expression trend in profile 0 was positively correlated with flavonoid content, while the gene expression trend in profile 79 was negatively correlated with flavonoid content at six developmental stages. The expression level of genes involved in the general phenylpropane pathway was higher than that of genes involved in the flavonoid biosynthesis pathway. A total of 37 genes involved in flavonoid synthesis were identified in A. membranaceus. The expression pattern of flavonoid-related genes was highly correlated with flavonoid content. Our study deepened the understanding of the flavonoid synthesis mechanism and provided useful resources for future studies on the high flavonoid molecular breeding of A. membranaceus.

“…However, it is well known that maize plant genotype is not the only factor determining corn pigmentation, as different environmental factors, altitude, temperature, and abiotic stress, in addition to maturation stage, could highly affect anthocyanins accumulation in corn [ 18 , 19 ], differently from cultivation practices (for example, potassium fertilization and seeding density) which have less impact, as reported by Jing et al for eighteen different purple corn cultivars from Perù [ 20 ]. The evaluation of the effect of location and genotype, in addition to their interactions, is useful for breeding, as demonstrated by Khampas et al [ 21 ] who selected a distinct genotype grown in a particular zone of Thailand, characterized by high pelargonidin-3- O -glucoside and peonidin-3- O -glucoside levels and high 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenger capacity.…”

Colored (orange, pink, red, purple, and blue) corn strongly attracted attention on its healthy properties mainly due to its anthocyanin and carotenoid composition which is also responsible for its pigmentation. The present review summarized the recent updates on the extraction and chemical characterization of the main plant secondary metabolites present in colored seeds, kernel, cob, husk, and silk. The main approaches used to stabilize the extracts have been discussed as well as their food and non-food uses. Both in vitro and in vivo (animal models) studies on the different effects (antibacterial, antimutagenic, antioxidant, and anti-inflammatory activities, effects on metabolic syndrome, diabetes, glucose and lipidic metabolism, and neuroprotection) of pigmented extracts on animal and human health have been summarized.
