“…Because of the unique structures and physiological activity of phytochemicals, some whole grains, such as corn could demonstrate remarkable antioxidant capacity . In Dong's report (Dong et al, 2014), total phenolic contents (298.8 ± 11.9, 283.4 ± 13.2, and 399.4 ± 18.9 mg GAE/100 g DW for CR, CC, and CS, respectively) were obviously lower than the values of Table 1 in this study. From Zhang's paper, total phenolic contents of sweet corn ranged from 38.00 to 57.04 mg GAE/100 g (Zhang et al, 2016), which were also much lower than most parts of ear sections.…”

“…The bound flavonoid contents of CB, CC, and ICS contributed more to the total, than those of CJ. The total flavonoid contents of CR, CC, and CS in Dong's paper (Dong et al, 2014), as well as the contents in Zhang's report (Zhang et al, 2016), were both less than those in this report, due to the ignorance of bound flavonoids and application of AlCl 3 method. The AlCl 3 method can not detect several types of flavonoids, which should be used for flavonoid analysis anymore .…”

“…The total antioxidant activity of corn was previously reported as 181.4 ± 0.9 μmol ASA equiv./g grain (Liu, ), and that of corn silk extracted by petroleum ether was 103.9 ± 6.1 μg/mL (ascorbic acid was 38.38 ± 3.61 μg/ml) (Liu et al, ). Moreover, the antioxidant capacity of CR, CC, and CS were performed by DPPH, ABTS, reducing power and FRAP by Dong (Dong et al, ). However, there were some limitations in these traditional antioxidant analysis, including underestimation of antioxidant capacity, water insolubility, environmental sensitivity, ignorance of metabolism, and bioavailability (Wolfe & Liu, ; Karadag, Ozcelik, & Saner, ).…”

This study aims to evaluate phenolics, flavonoids, total and cellular antioxidant activity (CAA), antioxidant capacity in ear sections of sweet corn. Corn cob and mature corn silk showed the highest contents of total phenolics and flavonoids (p < 0.05), respectively. Gallic acid and ferulic acid were the main free and bound phenolics in each ear part of corn, respectively (p < 0.05). Corn resident (CR) had a dominant role in total antioxidant activity and cellular antioxidant activity (CAA) (p < 0.05). Considering all the antioxidant properties, CR showed the best performance. The content of ferulic acid was correlated closely with CAA (R2 = 0.898, p < 0.05) and total antioxidant capacity (R2 = 0.971, p < 0.05), and total antioxidant capacity was also connected tightly with total phenolics (R2 = 0.886, p < 0.05). The results of this investigation were significant to enhance recognition and application of ear sections in food industry. Practical applications Sweet corn is widely cultivated in Asia, America, and other regions for fresh or industrial food because of high sugar, dietary fiber, and vitamins. However, there is no systematic assay on ear sections of sweet corn concerning antioxidant evaluation. The study investigated phytochemical profiles and antioxidant capacity in ear sections of sweet corn systematically, and made a comprehensive comparison of them combined with correlation analysis. The results indicated that ear sections of sweet corn, not only kernels, demonstrated high antioxidant capacity. Ear sections show promising potential application in food industry.

“…White maize is the most cultivated race (or hybrid varieties) in Mexico (Kato-Yamakake et al, 2009), therefore, their silks are most used as herbal medicine. The silks from white maize had a phenolic content of 2.42 g GAE kg −1 (Table 3), which was in agreement with reported for silks of white hybrid maize (3.99 g GA kg −1 ) (Dong et al, 2014). The silks from white and yellow maize (RG-w and RCr-Y) had significantly less flavonoids than silks from red maize (RC-r and RC-dr) ( Table 3), meaning that polyphenols in these silks are non-flavonoids.…”

“…These blue grains were reported with a polyphenol content of 12.8 g GAE kg −1 (Urias-Lugo, Heredia, Serna-Saldivar, Muy-Rangel, & Valdez-Torres, 2015) which was somewhat lower than we observed in the red silks of the same race (Table 3). According to other authors, the silks accumulate more polyphenols than other parts of the corn plant like the husks, rachis or even the grains of the maize cob (Dong et al, 2014;Shahzadi, Sheikh, Hameed, Jamil, & Ur-Rehman, 2015). White maize is the most cultivated race (or hybrid varieties) in Mexico (Kato-Yamakake et al, 2009), therefore, their silks are most used as herbal medicine.…”

Maize silks are used worldwide as a natural-based treatment for various illnesses. The biological activity of maize silks is mainly attributed to their content of polysaccharides and polyphenols. Therefore, it is worthwhile the identification of maize varieties or races that accumulate large amounts of these compounds in their staminate flowers. In the present study, the compositional and antioxidant properties of silks from three maize races (Cónico, Gordo and Cristalino) natives to Mexico were investigated. In general, the content of phenolic compounds including flavonoids and anthocyanins as well as the antioxidant capacity of maize silks from the landrace Cónico were higher than values reported in silks of hybrid maize varieties. The presence of the flavonoid maysin was confirmed in the silks of the landrace Cónico but not in the other two races. Whereas, the largest amount of polysaccharides was observed in silks from the landrace Cristalino. Propiedades de composición y captación de radicales de las inflorescencias femeninas de Zea mays (sedas del maíz) de razas nativas de maíces mexicanos RESUMEN Las sedas del maíz (estigmas de maíz) se utilizan en todo el mundo como un tratamiento natural para diversas enfermedades. La actividad biológica de las sedas del maíz se atribuye principalmente a su contenido de polisacáridos y polifenoles. Por lo tanto, es importante identificar variedades o razas de maíz que acumulen una gran cantidad de estos compuestos en sus estigmas. En el presente estudio se investigaron las propiedades de composición y antioxidantes de las sedas de tres razas de maíces nativos de México (Cónico, Gordo y Cristalino). El contenido de polifenoles como flavonoides y antocianinas así como la capacidad antioxidante fue mayor en las sedas de la raza Cónico que lo reportado previamente para las sedas de maíces híbridos. La presencia del flavonoide maysina fue confirmado en las sedas de la raza Cónico, pero no en las otras dos razas. Mientras que la mayor cantidad de polisacáridos se observó en las sedas de de la raza Cristalino.
