El ultrasonido (US) es la práctica de innovación más utilizada en la manufactura alimentaria. Objetivo: En este trabajo se valuó el resultado del procedimiento con US (40 KHz/130W/30°C /10, 20 y 30 min) en el secado por conducción a 60°C/2m/s de la uchuva (Physalis peruviana). Metodología: Se manejó un patrón difusional para relatar las cinéticas de secado y cuantificar la influencia del US en la difusividad efectiva de agua. Resultados: Tomando en consideración que el US ascenso significativo (p>0.05) la rapidez de secado en todos los ejemplares tratados con una reducción promedio del 38% en el tiempo de secado con respecto al tratamiento control; alcanzando perder peso del 78% en relación al peso inicial (4.21 a 0.93g.). Conclusiones: El modelo Logarítmico es el más conveniente para pronosticar las curvas experimentales de secado de la uchuva y reveló que el estudio de US creció tanto la difusividad positiva y el coeficiente de transmisión de masa, como confirman los valores del porcentaje de varianza explicada de 97.3 a 99.5%.

El presente trabajo de investigación tiene como objetivo determinar la concentración y tiempo de exposición de la colchicina para la duplicación del número cromosómico de Physalis peruviana L.  en  condiciones  in  vitro.  Para  tal  fin  primeramente  se  determinó  la  concentración  de  los reguladores de crecimiento para establecer en in vitro brotes de P. peruviana, posteriormente los segmentos nodales fueron sometidos a diferentes concentraciones de colchicina (0.05%, 0.10%  y 0.15 %) durante tres tiempos de exposición (12, 24 y 36 horas). El medio MS suplementado con 0.3 mg/L de BAP permitió establecer en in vitro brotes de P. peruviana. Con la aplicación de 0,05% y 0,10% de colchicina por un tiempo de exposición de 36 horas, se obtuvo plantas cuyos números cromosómicos van de 8n-8=88 y plantas mixoploides, teniendo en cuenta que el número cromosómico en condiciones normales encontrados fue de 4n-4=44 cromosomas. Las características morfológicas y anatómicas de las plantas que duplicaron su número cromosómico encontradas en el presente estudio son de poseer menor altura, mayor área foliar, estomas con menor densidad pero de mayor tamaño y con mayor número de cloroplastos.

Cape Gooseberry

Colombia is the main producer of cape gooseberry (Physalis peruviana L.), a plant known for its various consumption practices and medicinal properties. This plant is generally grown in eroded soils and is considered moderately tolerant to unfavorable conditions, such as nutrient-poor soils or high salt concentrations. Most studies conducted on this plant focus on fruit production and composition because it is the target product, but a small number of studies have been conducted to describe the effect of abiotic stress, e.g., salt stress, on growth and biochemical responses. In order to better understand the mechanism of inherent tolerance of this plant facing salt stress, the present study was conducted to determine the metabolic and growth differences of P. peruviana plants at three different BBCH-based growth substages, varying salt conditions. Hence, plants were independently treated with two NaCl solutions, and growth parameters and LC-ESI-MS-derived semi-quantitative levels of metabolites were then measured and compared between salt treatments per growth substage. A 90 mM NaCl treatment caused the greatest effect on plants, provoking low growth and particular metabolite variations. The treatment discrimination-driving feature classification suggested that glycosylated flavonols increased under 30 mM NaCl at 209 substages, withanolides decreased under 90 mM NaCl at 603 and 703 substages, and up-regulation of a free flavonol at all selected stages can be considered a salt stress response. Findings locate such response into a metabolic context and afford some insights into the plant response associated with antioxidant compound up-regulation.

Physalis peruviana calyces are used extensively in folk medicine. The crude ethanolic extract and some fractions of calyces were evaluated in order to explore antioxidant and anti-inflammatory activities. The anti-inflammatory activity was evaluated by the TPA-induced ear edema model. The antioxidant in vitro activity was measured by means of the superoxide and nitric oxide scavenging activity of the extracts and fractions. The butanolic fraction was found to be promising due to its anti-inflammatory and antioxidant activities. Therefore, a bio-assay guided approach was employed to isolate and identify rutin (1) and nicotoflorin (2) from their NMR spectroscopic and MS data. The identification of rutin in calyces of P. peruviana supports the possible use of this waste material for phytotherapeutic, nutraceutical and cosmetic preparations.
