The Antioxidation Effect of Brown Algae Extract

Abstract

This study attempted to investigate the functionality of <i>Dactylosiphon bullosus</i>, <i>Sporochnus radiciformis</i>, and <i>Zonaria diesingiana</i> extracts among algae as cosmetic ingredients. For this, antioxidant experiments were performed. <i>D. bullosus</i>, <i>S. radiciformis</i> and <i>Z. diesingiana</i> extracts were prepared with a 70% ethanol concentration to measure antioxidant activities. In terms of DPPH radical scavenging activity, <i>Z. diesingiana</i> was the highest with 94.20±0.28%. In ABTS radical scavenging activity, <i>Z. diesingiana</i> was the highest with 96.26±0.98%. In terms of the total phenolic contents and NO radical scavenging activity, <i>Z. diesingiana</i> was the highest with 47.19±2.07 mg gallic acid/g and 92.87±1.79%, respectively. The above results show that <i>Z. diesingiana</i> extract has the greatest antioxidant activity, confirming its potential as a cosmetic ingredient.
