Inhibitory Effects of Terminalia catappa on UVB‐Induced Photodamage in Fibroblast Cell Line

Abstract: This study investigated whether Terminalia catappa L. hydrophilic extract (TCLW) prevents photoaging in human dermal fibroblasts after exposure to UVB radiation. TCLW exhibited DPPH free radical scavenging activity and protected erythrocytes against AAPH-induced hemolysis. In the gelatin digestion assay, the rates of collagenase inhibition by TCL methanol extract, TCLW, and its hydrolysates were greater than 100% at the concentration of 1 mg/mL. We found that serial dilutions of TCLW (10–500 μg/mL) inhibited c… Show more

“…The cells were treated with non-cytotoxic concentrations of the test samples for 2 to 24 hours. After treatment with the test samples, the cells were subjected to the lethal dose of UV-B irradiation (200 mJ/cm 2 ) that can lead to approximately 50% cytotoxicity (302 nm, CL-1000 M, UVP, USA) [33]. The percent cell viability was assessed using the following Equation 2: % Cell viability = (X*100)/R…”
