ABSTRACT


This study optimized the extraction of sesamin and 4-hydroxy-sesamin from Cinnamomum camphora residue, yielding 0.3804 % under conditions of 86 ℃, 43 min, and a 1:8.39 solid-liquid ratio. The purified compounds showed 67.86 % and 78.87 % recovery rates via recrystallization. In LPS-induced BV-2 microglia, 4-hydroxy-sesamol (10-40 μmol/L) activated autophagy, reduced iNOS, COX-2, IL-6, IL-1β, TNF-α mRNA expression, and demonstrated neuroprotection without cytotoxicity, suggesting its potential in mitigating neuroinflammation.
