Alpha Glucosidase

Objective: The present work was to investigate the alpha amylase and alpha-glucosidase inhibitory activity of the selected edible seaweeds.Methods: The seaweeds namely Acanthophora spicifera, Gracilaria corticata, Gracilaria edulis, Ulva lactuca and Ulva reticulata were selected for this study. Six and eight hours of ethanol and aqueous extract were used for the estimation of alpha amylase using DNS method and alpha-glucosidase inhibition activity.Results: The study reported that the solvent from ethanol and aqueous in eight hours of extraction showed a higher inhibitory activity than six hours of extraction. Maximum of 89.1±0.96 and 79.55±3.08 percent of alpha-amylase and alpha-glucosidase inhibition activity were detected in the eight hours of aqueous extract (0.5 ml) of Ulva reticulata and Gracilaria edulis respectively. All the selected edible seaweeds had significant differences (p<0.05) in alpha amylase and alpha glucosidase inhibition activity between the selected seaweeds with different extracts.Conclusion: It was concluded that all the selected edible seaweeds have the potential to act as a potent inhibitor of the carbohydrate hydrolyzing enzyme. Thus, it was clear from the study that seaweeds incorporated in small amounts in the dishes consumed in the daily diet can bring a control on postprandial blood glucose level.

Chondracanthus Chamissoi

Objetivo: extraer y evaluar la actividad antiviral de los compuestos de Chondracanthus chamissoi y Chlorella peruviana contra DENV-2 en células Vero-76. Materiales y métodos: se extrajeron el carragenano de Chondracanthus chamissoi, los carbohidratos solubles de Chondracanthus chamissoi y Chlorella peruviana y se realizó la prueba de toxicidad en células VERO-76 y la evaluación de la actividad antiviral. Resultados: se obtuvieron carragenanos de la fase de esporofito y gametofito de Chondracanthus chamissoi, los mismos que fueron identificados, mediante infrarrojo, como k-carragenano. Por cromatografía se identificaron nueve azúcares (ribosa, xilosa, arabinosa, fructuosa, manosa, galactosa, sucrosa, maltosa y lactosa) en la muestra de carbohidratos solubles de Chondracanthus chamissoi fase gametofito y cuatro azucares (glucosa, sucrosa, maltosa y lactosa) en la de Chlorella peruviana. Los compuestos de Chondracanthus chamissoi y la solución de carbohidratos solubles de Chlorella peruviana no presentaron efecto citotóxico; los carbohidratos del extracto crudo de Chlorella peruviana sí los tuvieron. Todas las fracciones del extracto crudo de Chondracanthus chamissoi fase gametofítica fueron positivas por la prueba de reducción del número de placas(50) a la dilución 1:5. El k-carragenano de Chondracanthus chamissoi en ambas fases y los extractos crudos de carbohidratos solubles de Chondracanthus chamissoi, Chlorella peruviana y la solución de carbohidratos solubles de Chlorella peruviana inhibieron el crecimiento del virus dengue, pero no los carbohidratos del extracto crudo de la Chlorella peruviana. Conclusiones: los compuestos obtenidos de Chondracanthus chamissoi y Chlorella peruviana presentan actividad antiviral contra DENV-2 por lo cual es necesario continuar los estudios del potencial antiviral de estos compuestos fraccionados y purificados.
