초록

This study investigated the ingredients, anti-aging and anti-dementia activities of the Korean marine algae Silvetia siliquosa. The S. siliquosa solvent extracts were prepared with 70% ethanol, 80% methanol, and distilled water. The extraction yield range of various solvent extracts was 15.82–49.98%. The ethanol and methanol extracts had higher tyrosinase and collagenase inhibitory activities than those of the water extract. Meanwhile, all extracts exhibited high elastase inhibitory activity. Conversely, the methanol and water extracts exhibited the highest acetylcholinesterase inhibitory activity (IC50, 0.40 mg/mL) and β-secretase inhibitory activity (IC50, 0.81 μg/mL), respectively. These results indicate that S. siliquosa may be useful in food and pharmaceutical materials as a cosmetic and functional.
