Phytochemical characterization and bioactivity of extracts from different fruit...
Hamdoun, Ouafaa; Gonçalves, Sandra; Paixão Mansinhos, Inês Filipa; Rodríguez Solana, Raquel; Pereira-Caro, Gema; Moreno-Rojas, José ManuelThe objective of this study was to analyze the chemical profile of extracts from different fruit parts of the perennial arborescent cactus Opuntia leucotricha by applying ultra-high-performance liquid chromatography-high-resolution mass spectrometry (UHPLC-HRMS) and to evaluate their biological properties (antioxidant and enzyme inhibitory capacities). Extracts were obtained from the fruit pulp (without or with...
Nutrient deficiency-induced stress improves skincare effects and phytochemical ...
Paixão Mansinhos, Inês Filipa; Gonçalves, Sandra; Rodríguez Solana, Raquel; Pereira-Caro, Gema; Moreno-Rojas, José; Romano, AnabelaThe objective of this study was to investigate the impact of nutrient starvation on the growth, biochemical, metabolomic, and biological traits of Lavandula viridis L'H & eacute;r and Thymus lotocephalus G. L & oacute;pez and R. Morales in vitro cultures. In both species, a reduction in shoot growth and in the production of chlorophyll and carotenoids was observed in cultures grown under nutrient-deficient medi...
Impact of the pre-drying process on the volatile profile of on-farm processed E...
Moreno-Rojas, José Manuel; Yadira Erazo Solorzano, Cyntia; Tuárez García, Diego Armando; Pereira-Caro, Gema; Ordóñez Díaz, José LuisAiming to improve the quality of cocoa, preconditioning of cocoa after harvesting and before fermentation has become an on-farm processing step of great interest in recent times. The present work aimed to evaluate the influence of a pre-drying process on the volatile composition of Ecuadorian bulk (Forastero and CCN-51) and fine-flavour (ETT103 and LR14) cocoa at the end of primary processing. A total of 63 vol...
Effects of different heating treatments on the antioxidant activity and phenoli...
Tuárez-García, Diego Armando; Galván-Gámez, Hugo; Erazo Solórzano, Cyntia Yadira; Edison Zambrano, Carlos; Rodríguez Solana, Raquel; Pereira-Caro, GemaThe banana is a tropical fruit characterized by its composition of healthy and nutritional compounds. This fruit is part of traditional Ecuadorian gastronomy, being consumed in a wide variety of ways. In this context, unripe Red Dacca banana samples and those submitted to different traditional Ecuadorian heating treatments (boiling, roasting, and baking) were evaluated to profile their phenolic content by ultra...
Potential of bioactive compounds derived from underutilized fruit-bearing plant...
Kaur, Inderjeet; Sharma, Arun Dev; Samtiya, Mrinal; Pereira-Caro, Gema; Rodríguez Solana, Raquel; Dhewa, Tejpal; Moreno-Rojas, José ManuelIn nature, varieties of underutilized fruit-bearing plants are available and have remained underexploited for various reasons. However, the different parts of the plant, mainly the fruit, contributed considerably towards the sustainability of food as abundant sources of imperative phytochemical compounds and possess the potential for revenue generation and the conservation of ecological stability. Ethnobotanica...
Impact of metallic nanoparticles on In vitro culture, phenolic profile and biol...
Gonçalves, Sandra; Mansinhos, Inês; Rodríguez-Solana, Raquel; Pereira-Caro, Gema; Moreno-Rojas, José Manuel; Romano, AnabelaNanoparticles (NPs) recently emerged as new chemical elicitors acting as signaling agents affecting several processes in plant metabolism. The aim of this work was to investigate the impact of the addition of copper oxide (CuO), zinc oxide (ZnO) and iron oxide (Fe3O4 ) NPs (<100 nm) at different concentrations (1, 5 and 10 mg/L) to the culture media on several morphological, physiological and -biochemical param...
