The Stevia genus (Asteraceae) comprises around 230 species, distributed from the southern United States to the South American Andean region. Stevia rebaudiana, a Paraguayan herb that produces an intensely sweet diterpene glycoside called stevioside, is the most relevant member of this genus. Apart from S. rebaudiana, many other species belonging to the Stevia genus are considered medicinal and have been popularly used to treat different ailments. The members from this genus produce sesquiterpene lactones, diterpenes, longipinanes, and flavonoids as the main types of phytochemicals. Many pharmacological activities have been described for Stevia extracts and isolated compounds, antioxidant, antiparasitic, antiviral, anti-inflammatory, and antiproliferative activities being the most frequently mentioned. This review aims to present an update of the Stevia genus covering ethnobotanical aspects and traditional uses, phytochemistry, and biological activities of the extracts and isolated compounds.
La pandemia del Covid-19 impactó en los distintos niveles educativos, incluido el universitario. En este sentido, se adecuaron los contenidos de los seminarios y trabajos prácticos de Farmacognosia, materia del octavo cuatrimestre de la carrera de Farmacia de la Universidad de Buenos Aires, a la instancia virtual. A su vez, se recurrió a diversas estrategias e implementación de herramientas para fomentar la comunicación, la participación activa de los alumnos, el trabajo colaborativo y la comprensión de los contenidos. Los resultados obtenidos, referidos a la implementación de plataformas y recursos en los temas de procesos extractivos y grupos fitoquímicos I, son alentadores y demuestran el interés y participación de los alumnos contribuyendo al proceso de enseñanza-aprendizaje en la instancia virtual.
