Biotransformation by beta glucosidase enhances anti inflammatory metabolites in licorice using untargeted metabolomics.

ABSTRACT: Licorice (Glycyrrhiza uralensis) has traditionally been used as a food-derived herbal remedy for inflammation; however, the anti-inflammatory potential of its fermented extract in skin health is still unclear. This study investigated fermented licorice extract (FLE) for its effects against glyoxal-derived advanced glycation end products (GO-AGEs) and ultraviolet B (UVB)-induced skin inflammation in HaCaT keratinocytes. At 10 µg/mL, FLE reduced IL-6 levels by 46% and TNF-α levels by 52%, and significantly lowered PGE₂ levels. Mechanistic evaluation showed that FLE suppressed inflammatory signaling pathways, particularly nuclear factor-κB (NF-κB) and mitogen-activated protein kinases (MAPKs). Untargeted metabolomics identified fermentation-enhanced bioactive metabolites, including
