          Abstract

          Resumen La búsqueda de productos naturales, con determinadas funciones como aditivos alimentarios, son de gran interés investigativo por su proyección industrial. Por esta razón, el presente documento muestra los resultados de un estudio exploratorio sobre la actividad antibacteriana de un extracto hidroalcohólico de Calendula officinalis L., el cual se caracterizó mediante análisis fitoquímico, espectroscopía InfrarrojaAttenuated Total Reflection (IR-ATR), y cromatografía de gases acoplada a masas (CG-MS). El poder antimicrobiano se determinó sobre Pseudomona aeruginosa, Staphyloccocus aureus, y Candida albicans. Finalmente, se realizó una aplicación sobre fresa (Fragaria chiloensis L.), con el fin de observar el efecto sobre la vida útil del fruto, esto en las condiciones ambientales de temperatura 20 °C y humedad relativa 70%. Los resultados muestran que el extracto hidroalcohólico es una mezcla de diversos compuestos químicos, con buenas propiedades como biocompuestos activos. Finalmente se evidencia la presencia de taninos, carotenoides y compuestos fenólicos, entre otros, los cuales, de acuerdo con el estudio de actividad antimicrobiana, mejoraron la vida útil de la F. chiloensis.

          Abstract The current search for natural products, with some functions as food additives, are of great research interest due to their industrial projection. For this reason, this document shows the results of an exploratory study on the antibacterial activity of a hydroalcoholic extract of Calendula officinalis L., which was characterized by phytochemical analysis, Infrared Attenuated Total Reflection (IR-ATR) spectroscopy, and gas chromatography coupled to masses (CG-MS). The antimicrobial power was determined on Pseudomona aeruginosa, Staphyloccocus aureus, and Candida albicans. Finally, an application was made on strawberry (Fragaria chiloensis L.) to observe the effect on the useful life of the fruit, this in environmental conditions of temperature 20 ° C and relative humidity 70%. The results show that the hydroalcoholic extract is a mixture of various chemical compounds, with properties as active biocomposites. Finally, the presence of tannins, carotenoids, and phenolic compounds, among others, which, according to the study of antimicrobial activity, improved the useful life of F. chiloensis L is evidenced.

              Putative Roles of Plant-Derived Tannins in Neurodegenerative and Neuropsychiatry Disorders: An Updated Review

              Neurodegenerative and neuropsychiatric diseases are characterized by the structural and functional abnormalities of neurons in certain regions of the brain. These abnormalities, which can result in progressive neuronal degeneration and functional disability, are incurable to date. Although comprehensive efforts have been made to figure out effective therapies against these diseases, partial success has been achieved and complete functional recovery is still not a reality. At present, plants and plant-derived compounds are getting more attention because of a plethora of pharmacological properties, and they are proving to be a better and safer target as therapeutic interventions. This review aims to highlight the roles of tannins, ‘the polyphenol phytochemicals’, in tackling neurodegenerative diseases including Alzheimer’s and Parkinson’s diseases as well as neuropsychiatric disorders like depression. Among the multifarious pharmacological properties of tannins, anti-oxidative, anti-inflammatory, and anti-cholinesterase activities are emphasized more in terms of neuroprotection. The current review also throws light on mechanistic pathways by which various classes of tannins execute neuroprotective effects. Despite their beneficial properties, some harmful effects of tannins have also been elaborated.
