Nutritional profile, phytonutrient composition and biocidal properties of Portu...
Paschoalinotto, Beatriz H.; Chrysargyris, Antonios; Añibarro-Ortega, Mikel; Pires, Tânia C.S.P.; Mandim, Filipa; Dias, Maria Inês; Tzortzakis, NikolaosThe contribution of the ammonium: total nitrogen ratio (Nr0.01-0.15) in the nutrient solution on chemical profile and bioactive characteristics of Portulaca oleracea, investigated. Increased Nr levels resulted in increased proteins, total fats, carbohydrates and oxalic acid in leaves and stems, but decreased yield. The only detected tocopherol isoforms were alpha- and beta-tocopherol, with the former to reveal ...
Magnesium and manganese induced changes on chemical, nutritional, antioxidant a...
Oliveira, Izamara; Chrysargyris, Antonios; Finimundy, Tiane C.; Carocho, Márcio; Santos-Buelga, Celestino; Calhelha, Ricardo C.; Tzortzakis, Nikolaoscomposition was determined using standard methods. Free sugars, fatty acids, organic acids, tocopherols, and phenolic compounds were analyzed using various HPLC and GC devises. The extract’s antimicrobial, antioxidant, cytotoxicity, and anti-inflammatory activity were assessed. The results indicated that Mg enrichment negatively affected plant growth and mineral accumulation but improved photosynthetic performa...
The influence of magnesium and manganese cations on the chemical and bioactive ...
Oliveira, Izamara; Chrysargyris, Antonios; Finimundy, Tiane C.; Carocho, Márcio; Santos-Buelga, Celestino; Calhelha, Ricardo C.; Tzortzakis, NikolaosThis research investigated the effects of hydroponic cultivation with enriched concentrations of magnesium (+Mg), manganese (+Mn), a combination of +Mg and +Mn, or decreased concentrations of these minerals (control) on the nutritional, chemical, and bioactive attributes of purple and green basil. While Mn significantly increased the growth of purple basil and affected the composition of essential oil and miner...
Effects of the extraction techniques on the chemical composition and bioactive ...
Oliveira, Izamara; Chrysargyris, Antonios; Heleno, Sandrina A.; Carocho, Márcio; Calhelha, Ricardo C.; Dias, Maria Inês; Petrović, JovanaThe present study aims to determine the combined effect of cropping system and irrigation regime on the chemical composition and bioactive properties of lemon balm aerial parts. For this purpose, lemon balm plants were grown under two farming systems (conventional farming vs organic farming) and two irrigation levels (full irrigation vs deficit irrigation) and harvested twice throughout the growing period. The ...
Edible flowers as an emerging horticultural product: a review on sensorial prop...
Pires Junior, Eleomar de O.; Di Gioia, Francesco; Rouphael, Youssef; García-Caparrós, Pedro; Tzortzakis, Nikolaos; Ferreira, Isabel C.F.R.Background: The current consumer needs for functional and healthy foods, as well as for diversified diets that include a variety of food sources have created a market niche for novel horticultural products such as edible flowers and related food formulations. Scope and approach: Considering the increasing interest on this crop production sector during the last few years, this review aims to compile the most rel...
Comparison between different extraction methods in the recovery of bioactive mo...
Oliveira, Izamara; Heleno, Sandrina A.; Carocho, Márcio; Alves, Maria José; Vaz, Josiana A.; Dias, Maria Inês; Buelga, Celestino S.Melissa officinalis L., from the Lamiaceae family, is one of the most important medicinal and aromatic plants with potential in the market. With the passing of time, the use of medicinal plants in the treatment of some illness has gone from the simplest forms of local treatment to the industrial manufacture of phytotherapics. In addition to their medicinal effect, they can also be used in the form of infusions ...
Chemical composition and bioactive properties of purple french bean (Phaseolus ...
Fernandes, Ângela; Figueiredo, Sara Monteiro; Finimundy, Tiane C.; Pinela, José; Tzortzakis, Nikolaos; Ivanov, Marija; Soković, MarinaBiostimulants are a novel and eco-friendly agronomic tool with practical applications in alleviating negative effects of environmental stressors. The present work studied the effects of three biostimulant products (Nomoren (N), Twin-Antistress (TW), and X-Stress (XS)) under normal irrigation (W+) and water deficit irrigation conditions (W-) on the nutritional, chemical composition and bioactive properties of co...
Chemical and bioactive characterization of Melissa officinalis L. subjected to ...
Oliveira, Izamara; Heleno, Sandrina A.; Carocho, Márcio; Dias, Maria Inês; Santos-Buelga, Celestino; Petropoulos, Spyridon Α.; Tzortzakis, NikolaosMelissa officinalis L. (lemon balm) is a species of the Lamiaceae family which has been consumed for several decades in the form of decoctions, infusions or directly in food preparations. In addition to its recognized effects in helping digestion problems, rheumatism or headaches, several studies have demonstrated its antioxidant, hypoglycemic, hypolipidemic, antimicrobial, anticancer, antidepressant, anxiolyti...
The sustainable use of cotton, hazelnut and ground peanut waste in vegetable cr...
Petropoulos, Spyridon Α.; Fernandes, Ângela; Plexida, Sofia; Pereira, Carla; Dias, Maria Inês; Calhelha, Ricardo C.; Chrysargyris, AntoniosThe environmental burden from crop production byproducts is gradually increasing and necessitates the sustainable management of waste towards a circular economy approach. In the present study, three byproducts (cotton ginning waste (CGW), ground hazelnut husks (GHH) and ground peanut husks (GPH)) were evaluated in lettuce cultivation. For this purpose, the tested materials were incorporated in soil at two diffe...
Wild and cultivated centaurea raphanina subsp. Mixta: A valuable source of bioa...
Petropoulos, Spyridon Α.; Fernandes, Ângela; Dias, Maria Inês; Pereira, Carla; Calhelha, Ricardo C.; Di Gioia, Francesco; Tzortzakis, NikolaosCentaurea raphanina subsp. mixta (DC.) Runemark is a wild edible species endemic to Greece. This study evaluated the chemical composition and bioactive properties of wild and cultivated C. raphanina subsp. mixta plants. Wild plants had higher nutritional value than cultivated ones, whereas cultivated plants contained more tocopherols. Glucose and sucrose were higher in cultivated plants and trehalose in wild on...
