Photoprotective Effect of Ultrasonic-Assisted Ethanol Extract from <i>Sargassum horneri</i> on UVB-Exposed HaCaT Keratinocytes.

ABSTRACT: The present study investigated the photoprotective effect of the ultrasonic-assisted ethanol extract (USHE) from Sargassum horneri, a brown seaweed containing fucosterol (6.22 ± 0.06 mg/g), sulfoquinovosyl glycerolipids (C₂₃H₄₃O₁₁S, C₂₅H₄₅O₁₁S, C₂₅H₄₇O₁₁S, C₂₇H₄₉O₁₁S), and polyphenols, against oxidative damage in ultraviolet B (UVB)-exposed HaCaT keratinocytes. USHE indicated antioxidant activity in ferric-reducing antioxidant power (FRAP) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging. After screening experiments, 15.6, 31.3, and 62.5 µg/mL concentrations of USHE and ascorbic acid as positive control were selected to be used throughout the
