摘要: Se utilizaron extractos de Endocarpio y pericarpio cactus Cereus fricii para inhibir la corrosion del acero al carbono en soluciones HCl NaCl mediante ensayos gravimetricos. Los fueron obtenidos mecanicamente, las concentraciones fijadas caracterizadas por pruebas fitoquimicas analisis FTIR naturaleza inhibicion fue determinada calculo Gibbs Free Energy. establecio que los tienen presencia taninos, saponinas compuestos antioxidantes, lo corroborado el FTIR, mostrando picos absorbancia correspondientes a grupos OH COOH, siendo extracto endocarpio mayor proporcion. con una concentracion 5% mostraron un mejor rendimiento epicarpio, porcentajes 97,71 73,91% NaCl. La antioxidantes epicarpio favorecen metalica.
