Résumé
This investigation was performed with the purpose of researching the influence of pizza containing dried golden berry fruits (DGBF) at different doses against carbon tetrachloride - induced hepatotoxicity in rats. The study shows phenols content of golden berry. 25 male rats were used in the biological investigation. Rats were divided into five groups (5 rats in group) the investigation was 12 weeks. The first group (negative group) was given a basal diet and the second group (G2, G3, G4, and G5) was injected intramuscularly with carbon tetrachloride 2 ml/kg BW (50% v/v in liquid paraffin) weekly to induce hepatotoxicity. After the injury, group G3, G4 and G5 fed on 50% basal diet supplemented with 50%pizza containing 5, 10 and 15% DGBF. Findings indicate that DGBF had a high antioxidant activity, total phenol, flavonoids, ascorbic acid and carotenoids content. Rats fed 50% pizza containing (5,10 and 15%) DGBF had a lower serum total cholesterol, LDL cholesterol, triglyceride, urea, uric acid, creatinine, GOT, GPT, MDA and SOD compared to rats fed simply the basal diet (positive control). The DGBF was added to the pizza with different proportions, and its sensory properties were evaluated, and all proportions were proper to the panelists, compared to the control. The findings of this work suggest that golden berries could be used to treat and prevent hepatotoxicity patients.
Résumé
En el presente trabajo, es estudiada la diversidad genética de tres poblaciones atribuidas a ecotipos de aguaymanto, Physalis peruaviana. Las tres poblaciones eran atribuidas a los ecotipos Agroandino (provincia de San Pablo), Celendino (provincia de Celendín) y Cajabamba (provincia de Cajabamba) del departamento de Cajamarca. Se realizó la cuantificación proteica y evaluó el polimorfismo de las proteínas de reserva seminal (SSPs) mediante electroforesis en gel de poliacrilamida denaturante (SDS-PAGE). Además, se identificaron características bioquímicas de las proteínas seminales en esta especie. No se hallaron diferencias entre las tres poblaciones basados en la cuantificación proteica. Las globulinas (82.4%) fueron la fracción mayoritaria seguida por las albuminas (13.9%), glutelinas (3.7%) y prolaminas (0.7%). Sólo las albuminas mostraron polimorfismo, hallándose 21 proteínas entre ~ 6.5 a ~45 kDa y tres perfiles electroforéticos diferentes, los cuales fueron compartidos entre las poblaciones. Se identificaron las leguminas y vicilinas en la fracción globulina. Las glutelinas mostraron proteínas de mismo peso molecular (PM) a las leguminas; y las prolaminas sólo una banda de bajo PM. La población de San Pablo fue completamente homogénea a diferencia de la población de Cajabamba que mostró la mayor diversidad genética seguida de Celendín. No fue posible diferenciar las poblaciones designadas como ecotipos Agroandino, Cajabamba y Celendino basados en el análisis de proteínas seminales.
The genetic diversity of three populations designated as ecotypes of golden berry (Physalis peruaviana) is studied using protein quantification and polymorphism of seed storage proteins (SSPs) by denaturating polyacrylamide gel electrophoresis (SDS-PAGE). As well, biochemical characteristics of seed proteins were identified. The populations were from San Pablo province (Agroandino ecotype), Celendín province (Celendino ecotype) and Cajabamba province (Cajabamba ecotype), all from Cajamarca Department. There was not difference among the three populations based on protein quantification. Globulins (82.4%) were the majority fraction followed for albumins (13.9%), glutelins (3.7%) and prolamins (0.7%). Only albumins showed polymorphism, showing 21 proteins between ~6.5 to ~45 kDa and three different electrophoretic profiles, which were share among the three populations. Legumins and vicilins were identified in globulin fraction. Glutelins showed proteins of same molecular weight (MW) to legumins; and prolamins only a band of low MW. San Pablo province population (Agroandino ecotype) was completely uniform, while Cajabamba population showed higher genetic diversity followed by Celendin population. Our results shows that, based on seed proteins analyses is not possible to distinguish the three populations designated as Agroandino, Cajabamba and Celendino ecotypes.
