Function & Mechanism
Tyrosinase Inhibition
Competitive inhibitor of tyrosinase, the rate-limiting enzyme in melanin biosynthesis. Reduces L-DOPA oxidation with measurable IC50 values. Batch consistency verified through HPLC purity profiling.
Antioxidant Activity
4',7-dihydroxyflavanone backbone donates hydrogen to neutralize ROS. Dual electron-donating sites enable effective DPPH and ABTS radical scavenging, standardized through HPLC-verified purity.
Anti-Inflammatory Pathway
Suppresses NF-κB nuclear translocation and downregulates COX-2 expression. Reduces PGE2 production and pro-inflammatory cytokines (TNF-α, IL-6, IL-1β).
Hepatoprotective Activity
Stabilizes hepatocyte membranes and reduces serum ALT/AST under oxidative stress. Glycoside structure enables hepatic uptake and conversion to aglycone (liquiritigenin).
Applications
Cosmetic Manufacturing
Primary active for skin-brightening formulations at 0.5-2.0% inclusion. Tyrosinase inhibitor in serums, creams, and masks. Compatible with O/W and W/O emulsion systems. pH 5.0-7.0.
Nutraceutical Formulation
Antioxidant and hepatoprotective properties for dietary supplements. Bulk powder for capsule filling, tablet compression, or liquid extract blending. Standardized to 98% HPLC.
Food & Beverage Additive
Natural flavor enhancer and sweetener (100-500x sucrose). Suitable for combination with other natural sweeteners in reduced-sugar product development.
