ABSTRACT

Los conocimientos etnobotánicos constituyen aportes importantes en la vida del hombre y han permitido la aplicación del uso tradicional de las plantas medicinales, aromáticas, alimenticias. Así, en la comunidad de Ybabiyu, Distrito de Guazucua del Departamento de Ñeembucú, Paraguay, se reporta la utilización de las hojas de una especie vegetal conocida con el nombre de "hierba dulce" ("ka ́a he ́ê") (hierba dulce) como endulzante en sustitución del azúcar. El estudio fue cualitativo, observacional y descriptivo. El ámbito geográfico fue la Región del Ñeembucú, en la localidad conocida como Ybabiyu, distrito de Guazucua. La especie fue colectada en su hábitat natural, procedente de una propiedad privada de la zona. Fue identificada como Tessaria dodoneifolia (Hook. & Arn.) Cabrera (Asteraceae). Este uso, para esta especie, es reportado por primera vez para el Paraguay. A, además se describe las características y los aspectos ecológicos de la especie denominada "ka ́a he ́hierba dulceê" (Tessaria dodoneifolia) utilizada como endulzante de alimentos líquido, en la Región de Ñeembucú, Paraguay. Esta especie tiene amplia distribución y usos variados en países de América del Sur.


Ethnobotanical knowledge is important contributions in the life of man and allowed the application of traditional use of medicinal, aromatic, food plants. Thus, in the community of Ybabiyu, Guazucua District Department of Ñeembucú, the use of the leaves of a plant species known as "sweet plant" ("ka ́a he ́ê " (sweet plant) as a sweetener to replace sugar is reported . The study was qualitative, observational and descriptive. The geographical area was the region of Ñeembucú, in the locality known as Ybabiyu, Guazucua district. The species was collected in the wild, from a private property in the area. It was identified as Tessaria dodoneifolia (Hook. & Arn.) Cabrera (Asteraceae). This use is reported for the first time for Paraguay, plus features and ecological aspects of the species called "ka ́a he ́ê " (Tessaria dodoneifolia) used as a sweetener in liquid food, in the region of Ñeembucú, Paraguay.

ABSTRACT

El objetivo de este trabajo fue determinar el contenido de polifenoles y la capacidad antioxidante en bebidas elaboradas con panela (edulcorante natural obtenido de la concentración del jugo de caña), a fin de evaluar su potencial como fuentes de antioxidantes. En bebidas elaboradas con tres marcas de panela (A, B y C) sabor a limón, mandarina y durazno, se determinó el contenido de polifenoles totales utilizando el reactivo de Folin-Ciocalteu y la capacidad antioxidante por tres métodos: Eficiencia antirradical DPPH, poder reductor férrico (FRP) y capacidad de absorción de radicales de oxígeno (ORAC). El contenido de polifenoles varió de 0,76 a 1,26 g EAG/mL y 0,73 a 1,32 g EAT/mL, observando un mayor contenido para la bebida sabor a limón seguido por mandarina y durazno. Las bebidas tienen una Eficiencia Antirradical (EA) baja y los compuestos antioxidantes presentes muestran una cinética lenta. El poder reductor férrico fue de 8,28 a 10,41 mmol Fe+2/L. Los valores de ORAC variaron desde 1.536 hasta 5.220 μmol ET/100mL, siendo las elaboradas con la marca B la de mayor ORAC, seguida por la marca A y C. La interacción marca-sabor afecta de forma significativa el contenido de polifenoles totales y la EA, además el procesamiento térmico afecta significativamente la EA (p < 0,05). Los valores de polifenoles encontrados y la capacidad antioxidante mostrada por las bebidas elaboradas con panela indican que son productos potencialmente con capacidad antioxidante.


Polyphenols content and antioxidant capacity in beverages made with panela. The objective of this work was to determine the total polyphenols content and antioxidant capacity in beverages made with panela (a natural sweetener obtained after drying the unrefined whole sugarcane juice) in order to assess their potential as sources of antioxidants. In beverages made with three panela brands (A, B and C) with lemon, tangerine and peach flavors, the total polyphenols content was determined using the Folin-Ciocalteu ´s reactive and antioxidant capacity was determined by three methods: antiradical efficiency DPPH, ferric reducing power (FRP) and oxygen radical absorbance capacity (ORAC). The total polyphenols content ranged from 0.76 to 1.26 EAG g/mL and 0.73 to 1.32 EAT g/mL. The lemon flavored beverage showed the highest total polyphenols content followed by tangerine and peach flavored beverages. The three beverages had a low antiradical efficiency (AE) and the antioxidant compounds present in the beverages showed a slow kinetic. The ferric reducing power ranged from 8.28 to 10.41 mmol Fe+2/L. The ORAC values ranged from 1,536 to 5.220 μmol ET/100mL. The brand B showed the highest ORAC, followed by brands A and C. The brand-flavor interaction significantly affects the total polyphenols content and the EA, thermal processing also significantly affect the AE (p<0.05). The values of polyphenols and antioxidant capacity found in the beverages made with panela indicate that they are products potentially with antioxidant capacity.

ABSTRACT

The purpose of the present study was to investigate analgesic and anti-inflammatory properties of aspartame, an artificial sweetner and its combination with various opioids and NSAIDs for a possible synergistic response. The oral administration of aspartame (2-16mg/kg, po) significantly increased the pain threshold against acetic acid-induced writhes in mice. Co-administration of aspartame (2mg/kg, po) with nimesulide (2 mg/kg, po) and naproxen (5 mg/kg, po) significantly reduced acetic acid-induced writhes as compared to effects per se of individual drugs. Similarly when morphine (1 mg/kg, po) or pentazocine (1 mg/kg, po) was co-administered with aspartame it reduced the number of writhes as compared to their effects per se. Aspartame (4,8,16 mg/kg, po) significantly decreased carrageenan-induced increase in paw volume and also reversed the hyperalgesic effects in rats in combination with nimesulide (2 mg/kg, po).The study indicated that aspartame exerted analgesic and anti-inflammatory effects on its own and have a synergistic analgesic response with conventional analgesics of opioid and non-opioid type, respectively.

ABSTRACT

Se realizó un estudio comparativo in vitro en el cual se analizó el crecimiento del Streptococcus mutans (S. mutans) y el Lactobacillus acidophilus (L. acidophillus) en un medio mínimo con edulcorantes (xilitol, sorbitol, aspartamo, sucralosa y sacarina sódica), en concentraciones del 1, 2, 3, 4, y 5 por ciento, y con observaciones a las 0, 12, 24, 36 y 48 horas. El propósito fue analizar el potencial cariogénico de los sutitutos del azúcar. Se tomaron como control positivo la sacarosa y negativo el medio sin edulcorante. El crecimiento fue medido por medio de la absorbencia en los diferentes tiempos de observación. Los resultados se analizaron por medio de la prueba de H de Kruskall Wallis (p menor 0.01). Se encontró que el xilitol, el sorbitol y la sacarina sódica reducen el crecimiento in vitro del S. mutans y el L. acidophilus; en cambio, la sucralosa y el aspartamo lo estimulan

ABSTRACT

The present investigation was carried out to assess the chemical properties and the organoleptic quality of products sweetened by substituting sucrose with different ratios of high fructose corn syrup. The results revealed that replacement of sucrose with HFCS up to 50% showed no significant difference in the product color, flavor, texture and the overall acceptability. The panelist preference and the chemical properties of the products were better in case of lower replacement concentrations than the higher concentrations. It also gave the products some technological advantages, especially the absence of crystallization at refrigeration temperature. The combination of sucrose and HFCS not only add economic advantage by reducing the cost of the product, but also reduced the energy obtained from the same amount of the product prepared from sucrose alone
