“…4,5 Thereafter, numerous publications have confirmed melatonin's presence in the plant kingdom. [6][7][8][9] It seems that melatonin's presence in plants is a universal phenomenon. The levels of melatonin in plants are highly variable from specie to specie.…”

Melatonin is an environmentally friendly-molecule with broad spectrum antioxidant capacity. Melatonin is widely present in the plant kingdom. High levels of melatonin exist in an aquatic plant, the water hyacinth, which is highly tolerant of environmental pollutants. Elevated levels of melatonin probably help plants to protect against environmental stress caused by water and soil pollutants. To investigate the potential relationships between melatonin supplementation and environmental tolerance in plants, pea plants were treated with high levels of copper in the soil. The results show that copper contamination kills pea plants; however, melatonin added to the soil significantly enhanced their tolerance to the copper contamination and, therefore, increased their survival. Based on the theory and these preliminary data, we speculate that melatonin could be used to improve the phytoremediative efficiency of plants against different pollutants. Since melatonin is safe to animals and humans as well as being inexpensive, it may be a feasible and cost-effective approach to clean environmental contaminations.

“…The melatonin concentrations reported by Murch et al [22] also exceed by up to several orders of magnitude what appear to be the previous highest melatonin concentrations in plants and plant foods [11,12,14,25] reported for various medicinal herbs (<8,000 ng·g -1 ). [10,26] We also expect melatonin to concentrate in the skin and seeds of grapes. Thus, with levels of melatonin in various seed types all <200 ng·g -1 , [27] good agreement by different research groups on grape skin melatonin contents near or below 1 ng·g -1 , [23,24] and finished wine concentrations of up to 0.5 ng·mL -1 , [24,28] whole grape concentrations of 100,000 to 200,000 ng·g -1 as reported by Murch et al do not seem reasonable.…”

Melatonin and serotonin are important phytochemicals with hormonal, antioxidant, immunoactive, and neuroactive biological properties, and have been identified and quantitated in a broad range of fruits, vegetables, and derivative products. Relatively little is known about the temporal profiles of these compounds during fruit and vegetable development. Improved knowledge in this area would help guide our understanding of fundamental plant physiology, as well as potentially facilitate better control of melatonin and serotonin concentrations and relative abundances in functional foods. The current work synthesizes the current state-of-the-art regarding the presence and trends of these compounds during fruit and vegetable development. The literature reflects sometimes conflicting conclusions regarding the temporal profiles of melatonin and serotonin during fruit and vegetable ripening. At present, it is unclear whether consistent trends can be identified within a particular species, and the direction and magnitude of effects from different geographic locations and management practices.

“…Although immunoassay technique (ELISA) has been widely used for identification and quantification of melatonin in plants [19,[21][22][23], and some studies have shown good correlation with HPLC [24][25][26], ELISA does have some cross-reactivity with structurally similar compounds, potentially causing an overestimation of melatonin content. In this study, ELISA was used to confirm the presence of the melatonin in samples in the absence of mass spectra (MS) data.…”

Background: Melatonin content was screened in leaves of seven edible herbs used as sleeping aids in Thai traditional medicine. These plants are Piper nigrum L, Sesbania glandiflora (L.) Desv., Sesbania sesban (L.) Merr., Senna tora (L.) Roxb., Moringa oleifera Lam., Momordica charantia L. and Baccaurea ramiflora Lour. Dried leaves were extracted by sonication in methanol for six hours at room temperature, and then melatonin was purified by C18 solid phase extraction (SPE). Melatonin was then quantified by a validated RP-C18 HPLC method with fluorescent detection.
