Assessment of phytochemicals, enzymatic and antioxidant activities in germinated mung bean (Vigna radiata L. Wilezek)

Abstract

Summary Vitamin C, phenolic and flavonoid contents along with enzymatic and antioxidant activities were determined in germinated mung bean (Vigna radiate). Elevated levels of vitamin C 72.31 ± 0.62 mg/100 g FW and flavonoid content 85.57 ± 0.59 mg CE/100 g FW were estimated for euphylla after 6 days of germination. Moreover, maximum peroxyl radical scavenging activity 645.4 ± 28.5 μmol ASA equiv./100 g FW was also determined in euphylla. However, seed coat has the highest content of phenolic content (568.4 ± 8.8 mg GAE/100 g FW), whereas cotyledon depicted the highest ascorbate oxidase and peroxidase activities (396.5 ± 4.0 and 548.4 ± 2.8 min−1 g−1 FW, respectively). These findings revealed that euphylla in mung bean sprouts is the most bioactive part with significant level of phytochemicals. Therefore, after germination of 6 days, euphylla is the main source of nutrition in mung bean sprouts.

Comparison of phytochemical profiles, cellular antioxidant and anti‐proliferative activities in five varieties of wampee (Clausena lansium) fruits

“…The phenolic content of extracts was determined using the Folin-Ciocalteu method (Guo et al, 2012;Wang et al, 2017c). Gallic acid was used as standard in this assay.…”

Accumulating mechanism of γ‐aminobutyric acid in soybean (Glycine max L.) during germination

“…Sprouted soybean is a traditional and popular soybean product in Orient. Significant changes of the biochemical, nutritional and sensory characteristics have occurred in cereals during germination (Sharma et al, 2016;Wang et al, 2017). It is reported that the content of c-aminobutyric acid (GABA) increases significantly during germination in soybean, suggesting that germinated soybean could be a good source of GABA (Quinhone & Ida, 2015;Wang et al, 2015a;Huang et al, 2017).…”

Enhancement of Wheat Seed Germination, Seedling Growth and Nutritional Properties of Wheat Plantlet Juice by Plasma Activated Water

“…The vitamin C content of wheat plantlet juice was determined using the 2,6-dichloroindophenol (DIP) titrimetric method as reported previously (Wang et al 2017 ) with some modification. Briefly, 1.0 mL wheat plantlet juice and 9.0 mL chilled 2% (w/v) metaphosphoric acid buffer were added to a 50 mL conical flask for titration.…”
