Antioxidant activity of collagen/chitosan/ Archidendron clypearia extract composite materials

Abstract

In this study, we have synthesized a new material with good antioxidant activity. For the first time, Archidendron clypearia extract was included in the collagen/chitosan/TEOS mixture, the resulting material had antioxidant capacity evaluated through DPPH and ABTS radical scavenging and the total antioxidant capacity method, with low IC₅₀ values (IC₅₀ = 43.60 μg/mL and 46.57 μg/mL for DPPH and ABTS radical scavenging capacity) and the total antioxidant capacity was 83.06 ± 0.56 mg GA/g. The total content of phenolic and flavonoid compounds in Coll-Cs-TEOS-MD 0.5 is 36.87 ± 0.18 mg GA/g and 28.12 ± 0.15 mg QE/g, respectively. Material characteristics are examined through infrared spectroscopy (IR) and scanning electron microscope (SEM). Coll-Cs-TEOS-MD 0.5 material shows good antioxidant activities, which is very promising as a biocompatible material for biomedical applications.
