An analysis was made of the considerable increase in social networks when they were in confinement, therefore it was necessary to study two important aspects. The first was about the use that already existed before the pandemic arrived in different aspects of life, whether for leisure, work or study, followed by this compared with the considerable increase produced by the confinement of people, stress and the search of information. It was noted that one of the most frequent uses was to search for information regarding health issues and the pandemic, in many cases obtaining wrong information causing stress problems even for sick people. Many people began to opt for untrue information channels, which is why there was a notable increase in the use of social networks, even causing addiction to these channels., Se hizo un análisis del aumento considerable de las redes sociales al estar en confinamiento, por ello fue necesario estudiar dos aspectos importantes. El primero fue sobre el uso que ya había antes de que llegara la pandemia en diferentes aspectos de la vida ya sean por ocio, trabajo o estudio, seguido de esto se comparó con el considerable aumento producido por el encierro de las personas, el estrés y la búsqueda de información. Se pudo notar que uno de los usos más frecuentes fue el de búsqueda de información referente a temas de salud y a la pandemia, en muchos casos obteniendo informaciones erradas causando problemas de estrés incluso a las personas enfermas. Muchas personas empezaron a optar por canales de información pocos verídicos por lo que hubo un aumento notable en el uso de las redes sociales provocando incluso la adicción a estos canales.

The Natural dye demand is growing worldwide. This research is about the extracts of the fruits of (Mio mio) Coriaria ruscifolia L., from which little information is available, but we found in them anthocyanic and polyphenolic compounds which are great interest as bioactive compounds because of their antioxidant capacity. Nowadays, It is known that flavonoids including anthocyanins from (Mio mio) fruit has anticancer properties and other functional properties that made this study a great interest and can be used as a great source of antioxidant as natural dyes. The objective of the present study was to determine the bioactive compounds and antioxidant capacity of (Mio mio) fruit to use in the food industry. The extraction of their pigments were carried out with acidified methanol and into this extract their anthocyanin characteristics were determined by Visible UV spectroscopy, FTIR-ATR, then the composition of their anthocyanins were determined by HPLC. The content of total CAT anthocyanins were determined by differential pH method. This 440.22 (mg of cyanidin 3-glucoside / 100 g) in addition the total content of polyphenols PFT were quantified using the Folin-Ciocalteu method with 1820.41 (mg gallic acid / 100 g). The antioxidant capacity TEAC - ABTS has also been evaluated with 739.92 (µmoltrolox / 100 g). The results of the bioactive compounds and antioxidant capacity of (mio mio) fruit extracts were notably higher than those reported by different similar fruits. This impliesas a conclusion that these fruits can be used as a source of antioxidants in the form of natural dyes. In conclusion, the extracts of (mio mio) correspond to anthocyanin structures with a high antioxidant capacity, with a promising future for agro-industrial use., Frente al creciente incremento de enfermedades cardiovasculares, neurodegenerativos y cancerígenos, es menester el consumo de alimentos con alto poder antioxidante que neutralicen los radicales libres causantes de estas enfermedades. El objetivo de esta investigación fue caracterizar las antocianinas por espectroscopia UV Vis, FTIR-ATR y HPLC, determinar el contenido antocianinas (AT), polifenoles totales (PFT) y capacidad antioxidante en frutos nativos de mio mio (Coriaria ruscifolia L) de Abancay, Apurímac-Perú. Estas determinaciones se efectuaron por métodos de pH diferencial, Folin-Ciocalteu y capacidad antioxidante TEAC ABTS y DPPH. La extracción de pigmentos fue realizada con metanol acidificado con HCl al 0.01%. Los espectros Uv Vis y FTIR mostraron características antociánicas, identificándose por HPLC la cianidina como antocianina mayoritaria. El contenido de (AT) fue de 440.22 (mg cianidina 3-glucosido/100g), PFT de 371.71 (mg ácido gálico/100g), TEAC ABTS 134.40 (µmol trolox/g) y TEAC DPPH 82.70 (µmol trolox/g). En conclusión, los extractos del mio mio corresponden a estructuras antociánicas con una gran capacidad antioxidante, con un futuro promisorio para uso agroindustrial. En este trabajo también se observó correlación significativa entre el contenido de antocianinas totales y la capacidad antioxidante TEAC ABTS.
