“…Germination promoted the antioxidant activity of soybeans, black beans, red kidney beans, lentils, and chickpeas (p<0.05). These observations were in agreement with previous studies on enhancement of antioxidant profile in legumes by germination (Lin & Lai, 2006;Cevallos-Casals & Cisneros-Zevallos, 2010;Tarzi et al, 2012;Aguilera et al, 2014;Xue et al, 2016;Saleh et al, 2019).…”

“…However, in our study, TPC in germinated soybeans, chickpeas and lentils under normal condition significantly improved with 15.63, 34.64 and 18.84% relative increase, respectively. This elevation of TPC was consistent with observations by Saleh et al (2019), who noted the increase in chickpeas and lentils during germination. Similar results were also observed by Cevallos-Casals and Cisneros-Zevallos (2010), who reported increases of TPC in 13 edible seeds, including soybeans and lentils, after germination compared to ungerminated seeds.…”

“…Under normal condition, percentage increases of melatonin were in the following order: soybeans (160.96%), chickpeas (133.47%), lentils (86.90%), red kidney beans (67.14%), and black beans (49.97%). These findings concurred with Saleh et al (2019), who found that traditional germination of lentils, chickpeas and common beans led to a considerable elevation of melatonin in sprouts for three days, and the amounts increased with germination time.…”

“…These results agreed with Manchester et al 2000, who found that seeds of edible plants contained considerable amounts of melatonin (2-189 ng/g). Saleh et al (2019) also reported the contents of melatonin in raw lentils (4.79 ng/g), chickpeas (24.42 ng/g) and common beans (5.85ng/g), while Aguilera et al (2015) found lower amounts in lentils (0.5 ng/g) and kidney beans (1.0 ng/g). Sangsopha et al (2020) indicated that among the legumes they studied, soybeans exhibited the highest concentration of melatonin (56.49 ng/g), followed by red beans (54.79 ng/g).…”

Legumes are a potent source of bioactive ingredients that may be enhanced in seed germination particularly under saline condition. The levels of melatonin, its precursors, total phenolic compounds (TPC) and antioxidant activity of selected legume seeds were evaluated. Soybeans (Glycine max), black beans (Phaseolus vulgaris), red kidney beans (Phaseolus vulgaris), chickpeas (Cicer arietinum) and lentils (Lens culinaris) were germinated with distilled water and sodium chloride solution (67 mM NaCl), while ungerminated seeds served as control. Results indicated that legume seeds were a good dietary source of melatonin, serotonin and free tryptophan, as well as TPC. Germination of legume seeds, regardless of NaCl treatment, would stimulate melatonin, serotonin and tryptophan content, and also exhibited stronger antioxidant activity than ungerminated seeds. However, under saline condition, the levels of melatonin, serotonin, TPC and antioxidant activity were enhanced in soybeans, black beans and lentils, while chickpeas and red kidney beans exhibited higher levels of melatonin, TPC and antioxidant activity. These findings showed that the germination of legume seeds under saline stress to stimulate antioxidant defense mechanisms is a promising technique to improve the level of antioxidants like TPC, melatonin and its precursors, as well as antioxidant activity, in legume sprouts.

“…In legumes like adzuki bean, black bean, soybean, and white cowpea germination enhance phenolic contents and antioxidative activities [29]. Total phenols and flavonoids contents and antioxidant capacities in seeds and sprouts of broad bean, lupine, chickpea, lentil, fenugreek and common bean are abundantly found [30]. Sprouts of mung bean, radish, broccoli and sunflower have significant total polyphenol, flavonoid contents and antioxidant activities than their seeds [31].…”

Peanut sprouts are gaining increasing popularity as a potential source of functional food. The objective of this study was to investigate yield and food value of peanut sprouts of six Korean peanut genotypes (Daekwang, Akwang, Baekjung, Alogi, Pungan and Heugttangkong) from day 5 through 9. Functional compounds like polyphenol, flavonoid, and resveratrol contents were significantly (p\0.05) high in the sprouts compared to those in the seeds. Pungan yielded significantly (p\0.05) high sprouts followed by Alogi. However, antioxidant potentials and functional compounds in the sprouts varied significantly (p\0.05) with genotype, sprout part, and day after germination. Overall consideration of the yield, functional compounds, and antioxidant potentials of the sprouts suggested that more appropriate time of sprout harvest for Alogi and Pungan was day 5-7 and that for the other genotypes was day 5-8. The yield and functional properties of peanut sprouts significantly varied with genotypes, parts, and age.
