Propolis from the Monte Region in Argentina: A Potential Phytotherapic and Food Functional Ingredient

The aim of this review is to provide overall information on Argentine propolis and to shed light on its potential, especially the one from the Monte region so as to support future research in the field. Around 1999, the Argentine propolis began to be chemically and functionally characterized to give it greater added value. Because Argentina has a wide plant biodiversity, it is expected that its propolis will have various botanical origins, and consequently, a different chemical composition. To date, five types have been defined. Based on their functionality, several products have been developed for use in human and veterinary medicine and in animal and human food. Because the Argentine propolis with the greatest potential is that of the Monte eco-region, this review will describe the findings of the last 20 years on this propolis, its botanical source (Zuccagnia punctata Cav.), its chemical composition, and a description of markers of chemical quality (chalcones) and functionality. Propolis can regulate the activity of various pro-inflammatory enzymes and carbohydrate and lipid metabolism enzymes, as well as remove reactive oxygen and nitrogen species. Consequently, it can modulate metabolic syndrome and could be used as a functional ingredient in food. Furthermore, hydroalcoholic extracts can act against human and animal pathogenic bacteria and human yeast, and mycelial pathogenic fungi. The ability to stop the growth of post-harvest pathogenic bacteria and fungi was also demonstrated. For this reason, Argentine propolis are natural products capable of protecting crops and increasing the lifespan of harvested fruit and vegetables. Several reports indicate the potential of Argentine propolis to be used in innovative products to improve health, food preservation, and packaging. However, there is still much to learn about these natural products to make a wholesome use of them.EEA FamailláFil: Zampini, Iris Catiana. Consejo Nacional de Investigaciones Científicas y Técnicas.

Antimicrobial activity of Argentinean propolis against Staphylococcus isolated of canine otitis

Increasing resistance toward the available antibiotics by various microbial diseases pushed veterinarian to think about alternative therapies. Propolis is a natural compound well known since ancient times for its therapeutic effects and has been employed in traditional veterinary medicine. The aim of this study was to analyze the chemical composition of 12 propolis ethanolic extracts (PEEs) from different provinces of Northern Argentina and evaluate their antimicrobial activity against Staphylococcus strains isolated from canine otitis. Thirteen compounds (eight flavonoids, two chalcones and three phenolic acids) were identified by TLC, spectrophotometric methods and HPLC-DAD. PEEs were effective against Staphylococcus strains. The highest antibacterial activities were found in samples from Tucuman province. All propolis samples were considered bacteriostatic and the selection of resistant phenotypes did not occur in presence of Argentinean-PEE. Results of the present study indicate that propolis extracts might be an effective alternative against canine otitis-causing S. aureus strains in vivo.Fil: Salas, Ana Lilia.

Pot-Pollen and Pot-Honey from Stingless Bees of the Alto Balsas, Michoacán, Mexico: Botanical and Physicochemical Characteristics

The demand for stingless bees’ products (pot-honey and pot-pollen) has increased. No formal quality standards have been defined, which is very complex, because of the variety of species and types of honey specific to each region. For this reason, it is important to deepen the understanding of stingless bees’ honey characteristics. From the above, the aim of this chapter is to present the advances in the characterization of botanical origin of stingless bees’ honey, and the analysis of their physicochemical properties in the Alto Balsas, Michoacán, Mexico, as a way to contribute to the strengthening of new local economic strategies, generating information on the quality of the honey produced in the region

Zuccagnia-type Propolis from Argentina: A potential functional ingredient in food to pathologies associated to metabolic syndrome and oxidative stress

The effect of Argentine propolis extracts against enzymes related to metabolic syndrome and oxidative stress, as well as the botanical origin of raw propolis, were studied. Histological and chemical analyses of propolis samples revealed that the botanical origin is Zuccagnia punctata, an Argentine medicinal plant. The melissopalynological analysis showed both pollen grains of Z. punctata and the other plant species. This result indicates that the differences found in the botanical remains compared to the palynological studies may have been caused by the bees selecting resinous shrubs mainly of Z. punctata for the production of propolis and other plants with flowers for the production of honey. The richness of propolis was remarkable in two flavonoid precursors (2´,4´-dihydroxy-3´-methoxychalcone, 2´,4´-dihydroxychalcone), the major chemical components of Z. punctata. The hydroalcoholic extracts of Argentine propolis and Z. punctata were able to inhibit enzymes associated with the metabolic syndrome, including α-glucosidase, α-amylase and lipase, with IC50 values between 7 to 14, 37 to 48, and 13 to 28 µg/mL, respectively. Biological activity was mainly attributed to chalcones. Oxygen and nitrogen reactive species scavenging activity was determined by the assays of superoxide radical (O2•−), hydroxyl radical (HO•), hydrogen peroxide (H2O2), nitric oxide (NO•), and cation radical (ABTS•+). Results showed SC50 values between 115 to 278, 12.50 to 46; 39 to 92; 50 to 104.50 and 23 to 33.75 µg/mL, respectively. This study suggests for the first time that propolis from Argentina is highly effective in inhibiting enzymes related to the metabolic syndrome and in free-radical scavenging that would justify its use as a dietary supplement or as a functional ingredient in special food. Practical Application: Propolis from Catamarca, Argentina, is traditionally used as medicine and food. Its botanical origin is Zuccagnia punctata, an endemic plant species popularly used as a medicine in Argentina. Propolis has the ability to regulate the activity of enzymes involved in the carbohydrate and lipid metabolism, and consequently in metabolic syndrome. Besides, its antioxidant capacity makes it a natural product that can be used as a dietary supplement or as a functional ingredient in special foods. It is important to highlight that in the Argentine Food Code, propolis was incorporated in 2008 as a dietary supplement and the present results give major added value to this product.Fil: Salas, Ana Lilia.

Evaluación de parámetros nutricionales y sensoriales durante la conservación de pulpa de "chilto"

Desde hace unos años y dentro de un programa de Bioprospección de plantas nativas alimenticias y medicinales del NOA, nuestro instituto (INBIOFIV) estudia las propiedades nutricionales y funcionales de frutos de “chilto” (Solanum betaceum). Este es un fruto carnoso, comestible y nativo de las Yungas del NOA del cual se encuentran 3 variedades principales que se diferencian por el color del epicarpio (naranja o bola de chivo, roja y sangre de buey). En estudios previos hemos descripto las propiedades nutricionales y algunas potencialidades funcionales de los frutos bola de chivo y sangre de buey. En el marco de un proyecto premiado por ARCOR comenzamos a analizar productos derivados del mismo y su conservación en el tiempo. El objetivo de este trabajo fue analizar la conservación de la pulpa con y sin semilla de las variedades bola de chivo y sangre de buey en el tiempo, para lo que evaluamos parámetros nutricionales, físicos (color, pH) y sensoriales durante tres meses de conservación en frio (-20°C). El procesamiento de los frutos frescos permitió obtener pulpa libre de semillas o pulpa con semillas. Los resultados obtenidos demuestran la estabilidad nutricional (lípidos, proteínas y fibras), y en propiedades organolépticas como el color (luminosidad, parámetros de color) de la pulpa refrigerada. La estabilidad de la pulpa de “chilto” permitiría su utilización en la industria alimenticia para la fabricación de jugos, cocteles, dulces, entre otros.Fil: Orqueda, Maria Eugenia.

Contribution of food groups to energy, grams and nutrients-to-limit: The Latin American Study of Nutrition and Health/ Estudio Latino Americano de Nutrición y Salud (ELANS)

Objective: To quantify the energy, nutrients-to-limit and total gram amount consumed and identify their top food sources consumed by Latin Americans. Design: Data from the Latin American Study of Nutrition and Health (ELANS). Setting: ELANS is a cross-sectional study representative of eight Latin American countries: Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru and Venezuela. Participants: Two 24-h dietary recalls on non-consecutive days were used to estimate usual dietary intake of 9218 participants with ages between 15-65 years. 'What We Eat in America' food classification system developed by United States Department of Agriculture was adapted and used to classify all food items consumed by the ELANS population. Food sources of energy, added sugars, SFA, Na and total gram amount consumed were identified and ranked based on percentage of contribution to intake of total amount. Results: Three-highest ranked food categories of total energy consumed were: rice (10·3%), yeast breads (6·9%), and turnovers and other grain-based items (6·8 %). Highest ranked food sources of total gram amount consumed were fruit drinks (9·6%), other 100% juice (9·3%) and rice (8·3%). Three highest ranked sources for added sugars were other 100% juice (24·1 %), fruit drinks (16·5%), and sugar and honey (12·4%). SFA ranked foods were turnovers and other grain-based (12·6 %), cheese (11·9%), and pizza (10·3%). Three top sources of Na were rice (13·9%), soups (9·1 %) and rice mixed dishes (7·3 %). Conclusion: Identification of top sources of energy and nutrients-to-limit among Latin Americans is critical for designing strategies to help them meet nutrient recommendations within energy needs.Coca Cola Company///Estados UnidosHospital Infantil Sabará///BrazilInternational Life Science Institute//ILSI/ArgentinaUniversidad de Costa Rica//UCR/Costa RicaPontificia Universidad Católica de Chile///ChilePontificia Universidad Javeriana///ColombiaUniversidad Central de Venezuela//UCV/VenezuelaInstituto de Investigación Nutricional de Perú///PerúUCR::Vicerrectoría de Docencia::Salud::Facultad de Medicina::Escuela de Medicin

Food Sources of Shortfall Nutrients among Latin Americans: Results from the Latin American Study of Health and Nutrition (ELANS)

Increased consumption of energy-dense, nutrient-poor foods can lead to inadequate intakes of shortfall nutrients, including vitamin A, D, C, and E, dietary folate, calcium, iron, magnesium, potassium, and fiber. The objective was to examine the prevalence of inadequate intake of shortfall nutrients and identify food sources of shortfall nutrients in eight Latin American countries. Data from ELANS, a multi-country, population-based study of 9218 adolescents and adults were used. Dietary intake was collected through two 24 h Recalls from participants living in urban areas of Argentina, Brazil, Chile, Colombia, Ecuador, Peru, and Venezuela. Foods and beverages were classified using the adapted version of the NHANES “What We Eat in America” system. Nutrients inadequacy was estimated using the Institute of Medicine recommendations and descriptive statistics were calculated. Prevalence of inadequacy was above 50% for most of the nutrients, which the exception of vitamin C with a prevalence of inadequacy of 39%. Milk, cheese, seafoods, breads, and fruit juices/drinks were among the top 5 sources for each of the 10 shortfall nutrients examined. Many food categories were top contributors to more than one dietary component examined. Understanding the nutrient intake and food sources can help inform dietary guidance and intervention approaches.Coca Cola Company///Estados UnidosInternational Life Science Institute//ILSI/ArgentinaUCR::Vicerrectoría de Docencia::Salud::Facultad de Medicina::Escuela de Medicin

Socioeconomic status impact on diet quality and body mass index in eight Latin American countries: ELANS study results

Poor health and diet quality are associated with living within a low socioeconomic status (SES). This study aimed to investigate the impact of SES on diet quality and body mass index in Latin America. Data from the “Latin American Health and Nutrition Study (ELANS)”, a multi-country, population-based study of 9218 participants, were used. Dietary intake was collected through two 24 h recalls from participants of Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru and Venezuela. Diet quality was assessed using the dietary quality score (DQS), the dietary diversity score (DDS) and the nutrients adequacy ratio (NAR). Chi-squared and multivariate-variance analyses were used to estimate possible associations. We found that participants from the low SES consumed less fruits, vegetables, whole grains, fiber and fish and seafood and more legumes than those in the high SES. Also, the diet quality level, assessed by DQS, DDS and NAR mean, increased with SES. Women in the low SES also showed a larger prevalence of abdominal obesity and excess weight than those in the middle and high SES. Health policies and behavioral-change strategies should be addressed to reduce the impact of socioeconomic factors on diet quality and body weight, with gender as an additional level of vulnerability.UCR::Vicerrectoría de Docencia::Salud::Facultad de Medicina::Escuela de MedicinaUCR::Vicerrectoría de Investigación::Unidades de Investigación::Ciencias de la Salud::Centro de Investigación en Neurociencias (CIN)UCR::Vicerrectoría de Investigación::Unidades de Investigación::Ciencias Sociales::Instituto de Investigaciones Psicológicas (IIP

Meeting 24-h movement guidelines and markers of adiposity in adults from eight Latin America countries: the ELANS study

This study aimed to compare compliance with 24-h movement guidelines across countries and examine the associations with markers of adiposity in adults from eight Latin American countries. The sample consisted of 2338 adults aged 18–65 years. Moderate-to-vigorous physical activity (MVPA) and sedentary behavior (SB) data were objectively measured using accelerometers. Sleep duration was self-reported using a daily log. Body mass index and waist circumference were assessed as markers of adiposity. Meeting the 24-h movement guidelines was defned as≥ 150 min/week of MVPA; ≤ 8 h/ day of SB; and between 7 and 9 h/day of sleep. The number of guidelines being met was 0.90 (95% CI 0.86, 0.93) with higher value in men than women. We found diferences between countries. Meeting two and three movement guidelines was associated with overweight/obesity (OR: 0.75, 95% CI 0.58, 0.97 and OR: 0.69, 95% CI 0.51, 0.85, respectively) and high waist circumference (OR: 0.74, 95% CI 0.56, 0.97 and OR: 0.77, 95% CI 0.62, 0.96). Meeting MVPA and SB recommendations were related to reduced adiposity markers but only in men. Future research is needed to gain insights into the directionality of the associations between 24-h movement guidelines compliance and markers of adiposity but also the mechanisms underlying explaining diferences between men and women.Coca Cola Company///Estados UnidosHospital Infantil Sabará///BrazilInternational Life Science Institute//ILSI/ArgentinaUniversidad de Costa Rica//UCR/Costa RicaPontificia Universidad Católica de Chile///ChilePontificia Universidad Javeriana///ColombiaUniversidad Central de Venezuela//UCV/VenezuelaUniversidad San Francisco de Quito///EcuadorInstituto de Investigación Nutricional de Perú///PerúUCR::Vicerrectoría de Docencia::Salud::Facultad de Medicina::Escuela de Medicin

Development of a Bioproduct for Medicinal Use with Extracts of Zuccagnia-type Propolis

Propolis with a botanic origin in Zuccagnia punctata Cav. (Fabaceae), a plant species widely distributed in the Argentinean Monte region, was used to produce a standardized propolis extract by biological activity and chemical composition. In this paper the effect on microorganisms isolated from otitis was determined. The extract was active against different Staphylococcus strains with MIC and MBC values (75 and 150 µg DE/mL, 200 and 600 µg DE/mL, respectively) and with MIC values of 800 µg DE/mL against Proteus mirabilis. A pharmaceutical product, ear drops containing this extract as bioactive was developed. Stability of ear drops was evaluated for 6 months, and their biological activity, physical and phytochemical properties were preserved. Ear drops showed inhibitory activity on pro-inflammatory enzymes such as lipoxygenase (IC50 values 90 and 100 µg DE/mL), free radical-scavenging effect (SC50 values 23 and 30 µg DE/mL), antihelmintic (LC50 values 70 and 71 µg DE/mL), anti-candida (400 µg DE/mL) and antibacterial activity against Gram-positive bacteria (200µg DE/mL) at zero time and during six month-storage, respectively. The content of two chalcones, chemical markers of Zuccagnia-type propolis was quantified and its level was maintained while stored at room temperature. Its toxicity was also assayed. Our results are interesting since the extract and ear drops of Zuccagnia-type propolis developed could be promising for use in alternative medicine or phytomedicine as antibacterial, anti-candida, antihelmintic, anti-inflammatory and antioxidant.Fil: Salas, Ana Lilia.
