چکیده انگلیسی
Various biological activities of glabridin have been reported in literature, however, the bioavailability and clinical application was limited by its low water solubility. In this study, we developed a novel inclusion complex of glabridin and hydroxypropyl-β-cyclodextrin (HP-β-CD) that features improved solubility and bioactivity. The formation of the inclusion complex was supported by data from FT-IR, PXRD, SEM and NMR. Specifically, the NMR results indicated that the aromatic ring of glabridin was merged into and located at the narrow side the cavity of HP-β-CD. The in vitro tests showed that the formation of the inclusion complex led to 9 times increase in the DPPH radical-scavenging capacity and 20 times increase in the tyrosinase inhibitory activity compared to the free glabridin at the same concentration. Therefore, the glabridin/HP-β-CD inclusion complex adds a promising strategy for the clinical application of glabridin in the future.
