“…Phenolic compounds were extracted as described in our previous work by Serradilla et al [ 29 ]. Briefly, 10 g of homogenate was mixed with 50 mL of methanol (0.1% HCl), manually shaken and stored at −20 °C for 24 h. Separation and quantification were performed by HPLC-DAD/FLD, as described by Manzano et al [ 30 ], using a Series 1100 chromatograph (Agilent) equipped with a degasser, a quaternary pump, a Gemini column (NX-C18, 150 × 4.6 mm, 3 µm) thermostated at 40 °C. Phenolic compounds were calculated using calibration curves that were made with standards and following the method of external standards.…”

Melatonin (N-acetyl-5-methoxytryptamine) is involved in multiple functions in plants. However, its role in some metabolic pathways and exogenous application’s effect on fruits is still unclear. Furthermore, the effects of pre-storage melatonin treatment on sensory traits and consumer acceptance of cherries have yet to be studied. For this reason, the early sweet cherry cultivar ‘Samba’ harvested at the commercial ripening stage was treated with different melatonin concentrations (0.1, 0.3, and 0.5 mmol L−1) and stored for 21 days under controlled cold temperature and humidity. The standard quality, respiration rate, postharvest aptitude, sensory quality, phenols, and antioxidant systems (non-enzymatic and enzymatic) were analysed at 14 and 21 days of storage. Postharvest treatment with melatonin 0.5 mmol L−1 improved firmness and reduced weight loss and non-commercial fruit percentage while increasing respiration rate, lipophilic antioxidant activity, and ascorbate peroxidase enzyme activity. Furthermore, the treated cherries showed better sensory qualities, such as uniformity of colour and skin colour, as well as being sourer and showing better consumer acceptance and liking after 14 days of storage. Therefore, we conclude that the 0.5 mmol L−1 concentration is effective on the standard, sensory, and bioactive quality of early sweet cherries and can be considered an eco-friendly tool for maintaining the postharvest quality of early cherries.

“…The common structural characteristics all phenolics share are aromatic rings, hydroxyl groups and, commonly, electron double bonds. Phenolics have been extracted using ethanol, methanol, water, ethyl acetate, and dichloromethane by the use of simple solvent extraction under reflux, Soxhlet extraction, assisted ultrasound extraction, and assisted microwave extraction [ 37 , 38 , 39 , 40 , 41 ]. Different extraction methods and solvents have been shown to target the extraction of different phenolics [ 41 , 42 ].…”

The pharmacological activities in bioactive plant extracts play an increasing role in sustainable resources for valorization and biomedical applications. Bioactive phytochemicals, including natural compounds, secondary metabolites and their derivatives, have attracted significant attention for use in both medicinal products and cosmetic products. Our review highlights the pharmacological mode-of-action and current biomedical applications of key bioactive compounds applied as anti-inflammatory, bactericidal with antibiotics effects, and pain relief purposes in controlled clinical studies or preclinical studies. In this systematic review, the availability of bioactive compounds from several salt-tolerant plant species, mainly focusing on the three promising species Aster tripolium, Crithmum maritimum and Salicornia europaea, are summarized and discussed. All three of them have been widely used in natural folk medicines and are now in the focus for future nutraceutical and pharmacological applications.

“…Frozen fruits were pitted and homogenised using an Omni Mixer homogeniser (Omni International, Marietta, GA, USA), and 2 g were used to determine phenolic compounds and another 2 g to determine total antioxidant activity (TAA). Phenolic compounds analysis was performed as described in a previous work 16 . Results were expressed as g kg −1 FW.…”

BACKGROUNDEarly sweet cherries have a high economic impact on cherry growers but have poorer quality characteristics and shorter shelf‐life than late cherries. Melatonin has been proposed as a biostimulant that regulates plant and fruit growth and increases fruit quality and shelf‐life but, in general in fruit and vegetables, there is controversy about its effects. Therefore, this work aimed to evaluate the impact of exogenous preharvest melatonin applications at dusk on the quality and bioactive compounds of two early sweet cherry cultivars.RESULTSM3 and M5 (3·10‐4 and 5·10‐4 M melatonin, respectively) treatments effectively enhanced the endogenous melatonin and hydroxycinnamic acid concentration, enhancing the functional properties of the fruit. Additionally, the M5 treatment enhanced skin colour and consumer acceptance of 'Samba', while the M3 treatment improved cherry size in 'Sandon Rose'.CONCLUSIONPreharvest melatonin applications at dusk could be included in the scheduled preharvest treatments for early cherry cultivars in order to improve the quality and to stimulate the functionality of the fruit. However, further studies are needed to adjust the concentration depending on the cultivar and the objective pursued.This article is protected by copyright. All rights reserved.
