| Introduction: the idea to explore at least some of the regions diversity such as the Colombian Orinoco through bioprospecting study of Lacmellea standleyi (Woodson) Monach. arises as a consequence of ignorance of much of the floristic richness in Colombia and the potential relevance of much of this in the nutrition, health and industry. Objective: to evaluate the antioxidant potential, nutritional and phenolic content, antimicrobial activity, and safety degree of aqueous, ethanol, and ethyl acetate extracts of Lacmellea standleyi fruits in three different ripening stages. Methods: the nutritional value was evaluated using standardized methods to full fruit in its three ripening stages. Each of the extracts was chemically characterized by spectrophotometric... |

| Introducción: Mollinedia racemosa (Schltdl.) Tul. (romadizo), es una especie usada por grupos indígenas y comunidades campesinas de la cuenca del Orinoco colombiano, empleada para tratar fiebres, dolores de cabeza y problemas de estómago, especialmente en el tratamiento del resfriado y como analgésico. Objetivo: evaluar el potencial antioxidante de las hojas de M. racemosa (romadizo). Métodos: se preparó un macerado etanólico de hojas (relación 1:15, vegetal/solvente), renovando el solvente cada 24 h hasta agotar la muestra. El extracto se filtró, se concentró a presión reducida y se almacenó (4 ºC). Se valoró el contenido de compuestos fenólicos, flavonoides y de flavonoles totales. Se estableció además la concentración de alcaloides que posee la planta.... |

| Introduction: Sida cordifolia L. (Malvaceae) is a weed about which not much is known in Colombia. This plant is used in folk medicine to treat oral mucosa, blennorrhea, asthma and bronchitis.In Brazil it finds application as an anti-inflammatory,while in Colombia its "baba" is used for treating hair loss, constipation and internal fever, among other ailments. Objectives: to quantify the saponoside content and evaluate its antioxidant and antifungal functionality. Methods: we prepared organic, aqueous and hydroalcoholic extracts from the aerial section of the plant. The saponoside material was quantified by the DNS and p-anisaldehyde methods. The most concentrated extracts were selected for antioxidant and antifungal assays. Results: it was found that Sida... |
