Abstract:
Objective: The aim of this research was to evaluate the photoprotective effect of Oreocallis grandiflora hydroalcoholic extract (OGHE) againstultraviolet (UV)B-induced cell death model on a strain of Escherichia coli (ATCC 25922) and to determine the sun protection factor (SPF) using theequation proposed by Mansur.Methods: OGHE was obtained from leaves of O. grandiflora, following a standardized methodology. In short, O. grandiflora leaves were extracted withethanol 70% v/v and defatted with n-hexane, hydroalcoholic fraction was concentrated under controlled conditions through rotary evaporato

A fin de poder usar extractos de plantas nativas en aplicaciones medicinales, cosméticas, anticorrosivas, entre otras; el objetivo del presente trabajo fue evaluar la actividad antioxidante, así como el contenido de flavonoides y compuestos fenólicos totales de los extractos etanólicos e hidroalcohólicos de las hojas de Buddleja inkana (quisuar), Oreocallis grandiflora (cucharilla) y Chuquiraga spinosa (huamanpinta). La medición de la actividad antioxidante: FRAP, DPPH y ABTS·+ así como el contenido de flavonoides y compuestos fenólicos totales, se realizó por el método de lector en microplaca

Abstract:There is still much to learn about pollination ecology in areas of high species diversity, such as the Neotropical region. For example, the role of non-flying mammals in pollination is largely unknown in the Neotropical areas, despite the importance of this group in the pollination of plants in other regions. Here we report evidence for flower visitation by a rodent to Oreocallis grandiflora (Proteaceae) in our study site in the southern Andes of Ecuador. For a period of 241 h, camcorders equipped with infrared lights revealed 22 occurrences of floral visitation by Microryzomys altiss

Las plantaciones de pino han impactado negativamente la biodiversidad y el establecimiento de flora nativa en Ecuador. Evaluamos si la remoción de acículas facilita el establecimiento de Oreocallis grandiflora en una plantación del sur del país; realizamos siembra directa de semillas en parcelas con y sin acícula. Nuestros resultados mostraron que la remoción no tuvo efecto estadísticamente significativo sobre la emergencia (p &gt; 0.05), pero sí sobre la supervivencia (p &lt; 0.0001). Después de 22 semanas, registramos una supervivencia &gt;86% sin acícula y 7% con acícula. Dos años después,

Abstract:
Oreocallis grandiflora (Lam.) R. Br. is an Ecuadorian species belonging to the Proteaceae family, commonly known as cucharillo (Loja and Zamora provinces), cucharilla (Sierra region), gañal (Bolívar province), and algil (Chimborazo province). Its leaves and flowers, collected during blooming, are traditionally used for oral administration to treat liver diseases, vaginal bleeding, and ovary/uterus inflammation and as digestive, diuretic, and hypoglycemic remedy. Related literature does not report any scientific evidences regarding the chemical composition of the used parts of this species (lea

Uno de los aspectos importantes a considerarse en la producción eficiente de plántulas con fines de restauración es la calidad de semillas y su variabilidad. El objetivo de este estudio fue evaluar los parámetros de semillas de acuerdo con las reglas del “International Seed Testing Association” entre diferentes árboles madre o individuos de siete especies nativas (Cedrela montana, Morella pubescens, Inga acreana, Tabebuia chrysantha, Ocotea heterochroma, Oreocallis grandiflora y Myrcianthes rhopaloides) en dos bosques de montaña del sur del Ecuador.
