摘要

The aim of the present study was to synthetize new phenol-based materials through the sol-gel approach. 5-O-caffeoyl quinic acid, a natural antioxidant better known as chlorogenic acid (CGA), was incorporated within silica matrix obtaining orange colored hybrid materials, characterized by Fourier Transform InfraRed (FTIR) and UltraViolet-Visible (UV-Vis) spectroscopic techniques. In vitro soaking tests in simulated body fluid (SBF) was performed to evaluate the new materials' bioactivity and the formation of a hydroxyapatite layer was observed on the hybrid surface by SEM/EDX analysis. Moreover, CGA-based materials were biocompatible to murine and mammalian cells as assessed by tetrazolium dye (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide)-based microtitration assay (MTT assay) and exerted antioxidant capability by scavenging DPPH and ABTS~+ radicals.
