Objective: determine the content of phenolic compounds and the anti inflammatory activity of E. umbellata extracts on plasma erythrocytes. Methodology: Samples of leaves and stems of E. umbellata collected following appropriate protocols were used. The extracts were obtained by standard techniques and analyzed for their content of total phenols, flavonoids and anthocyanins using UV-visible spectrophotometry. The anti-inflammatory activity was evaluated at concentrations of 10, 100, 500 and 1000 µg/mL using a plasma erythrocyte model. Results: Stems of E. umbellata exhibited significantly higher content of total phenolics, flavonoids and anthocyanins compared to leaves. Traces of catechins were detected in both parts of the plant. However, alcoholic extracts of leaves and stems did not show significant anti-inflammatory effects at the concentrations evaluated. Conclusion: E. umbellata ex...

Se realizó un estudio farmacognóstico de las raíz, corteza y hojas de Campsiandra angustifolia (huacapurana), el estudio de tipo experimental permitió determinar inicialmente las características morfológicas para reconocimiento de la especie, luego se identificó cualitativamente los metabolitos secundarios encontrándose la presencia de triterpenos (raíz)/ esteroides (raíz, corteza), aminoácidos (raíz ), flavonoides (raíz, corteza y hoja ) saponinas (raíz, corteza y hoja ), taninos (corteza )/fenoles(raíz, hoja) El análisis microquímico de la nervadura central de la hoja dio positivo a grasas/ aceites y ligninas. El análisis de los parámetros físico-químicos de la droga cruda según las Normas Ramales Para Drogas Crudas del MINSAP; permitió determinar en raíz, corteza y hoja de la huacapurana valores de humedad 11.47% (raíz),12.54% ( corteza), 10,51% (hojas); de ce...
