“…Higher antioxidant activities (DPPH radical scavenging activity and FRAP) and TPC of germinated seeds compared those of raw seeds were also observed in germinated alfalfa seeds (Medicago sativa L.), as well as in lentil (Lens culenta L.), mung bean (Vigna radiate L.), onion (Allium cepa L.), broccoli (Brassica oleraceae L.), red cabbage (Brassica oleraceae capitata rubra L.) and radish (Raphanus sativus japonicum L., Raphanus sativus rambo L., Raphanus sativus sinicum rosae L.) (Aguilera et al, 2015). Fouad and Rehab (2015) also found that germination caused a significant increase in DPPH radical scavenging activity, total phenolic content and free amino acid content in germinated lentils (p≤0.05).…”

AbstractThis research evaluated effect of germination period and acid pretreatment on chemical composition and antioxidant activity of rice bean sprouts. Moisture, total phenolics, reducing sugar and B vitamins (thiamine, riboflavin, and niacin) content of steamed sprouts increased with increasing germination time (p≤0.05). Pretreatment with 1% (w/v) citric acid for 6 hours significantly increased the total phenolic content. The 18-hour-germinated rice beans showed the highest crude protein content, as determined using the Kjeldahl method. During germination, acid pretreatment led to a significant decrease in the intensity of the 76-kDa band. Germination caused a significant increase in radical scavenging activity and ferric reducing antioxidant power, especially in sprouts from citric acid-treated seeds. The antioxidant activities of the ethanolic extracts from both pretreated beans and the control were 1.3-1.6 times higher than those obtained from the water extracts. Major phenolics found in both 0-hour and 18-hour-germinated rice beans were catechin and rutin.

“…Given the potent health effects of melatonin, many foods have been tested in the past decades and melatonin was identified and quantified in both animal foods and edible plants [21,22]. Huge differences of melatonin concentrations were reported among various food species and/or organs, ranging from pg/g to mg/g [22,23]. Additionally, it was well documented that the consumption of melatonin-rich foods may induce the potential health impacts by significantly increasing the serum melatonin concentration and antioxidant capacity in human beings [24].…”

Dietary Sources and Bioactivities of Melatonin

Insomnia is a serious worldwide health threat, affecting nearly one third of the general population. Melatonin has been reported to improve sleep efficiency and it was found that eating melatonin-rich foods could assist sleep. During the last decades, melatonin has been widely identified and qualified in various foods from fungi to animals and plants. Eggs and fish are higher melatonin-containing food groups in animal foods, whereas in plant foods, nuts are with the highest content of melatonin. Some kinds of mushrooms, cereals and germinated legumes or seeds are also good dietary sources of melatonin. It has been proved that the melatonin concentration in human serum could significantly increase after the consumption of melatonin containing food. Furthermore, studies show that melatonin exhibits many bioactivities, such as antioxidant activity, anti-inflammatory characteristics, boosting immunity, anticancer activity, cardiovascular protection, anti-diabetic, anti-obese, neuroprotective and anti-aging activity. This review summaries the dietary sources and bioactivities of melatonin, with special attention paid to the mechanisms of action.

“…The beneficial effects of MT have been proved for the improvement of several stages of the plant life cycle, such as, germination (Aguilera et al, 2015), cell division (Park and Back, 2012), root development (Passaia et al, 2014; Wang Q. N. et al, 2016), leaf senescence (Lee and Back, 2017), and crop production (Wei et al, 2014). In addition, it has been proved that MT efficiently regulates antioxidant defense systems (Szafrańska et al, 2016), increases photosynthetic efficiency (Zheng et al, 2017), reduces chlorophyll degradation, and delays leaf senescence (Liang et al, 2015) under abiotic stresses.…”

Melatonin Has the Potential to Alleviate Cinnamic Acid Stress in Cucumber Seedlings

Cinnamic acid (CA), which is a well-known major autotoxin secreted by the roots in cucumber continuous cropping, has been proven to exhibit inhibitory regulation of plant morphogenesis and development. Melatonin (MT) has been recently demonstrated to play important roles in alleviating plant abiotic stresses. To investigate whether MT supplementation could improve cucumber seedling growth under CA stress, we treated cucumber seeds and seedlings with/without MT under CA- or non-stress conditions, and then tested their effects on cucumber seedling growth, morphology, nutrient element content, and plant hormone. Overall, 10 μM MT best rescued cucumber seedling growth under 0.4 mM CA stress. MT was found to alleviate CA-stressed seedling growth by increasing the growth rates of cotyledons and leaves and by stimulating lateral root growth. Additionally, MT increased the allocation of newly gained dry weight in roots and improved the tolerance of cucumber seedlings to CA stress by altering the nutrient elements and hormone contents of the whole plant. These results strongly suggest that the application of MT can effectively improve cucumber seedling tolerance to CA stress through the perception and integration of morphology, nutrient element content and plant hormone signaling crosstalk.
