Encapsulation of quercetin in β-cyclodextrin and (2-hydroxypropyl)-β-cyclodextrin cavity:In-vitrocytotoxic evaluation

The formation of host-guest inclusion complex of Quercetin (QRC) with β-Cyclodextrin (β-CD) and (2-Hydroxypropyl)-β-Cyclodextrin (HP-β-CD) is prepared by various methods such as physical method (PM), kneading method (KM) and co-precipitation method (CP). The solid inclusion complex is characterized by UV, Fluorescence, FT-IR, SEM, powder XRD and TG/DTA analysis. The cytotoxic activity of the solid complex is performed against breast cancer cell line and it is noticed that there is better activity than the QRC alone. Hence, the solid complex showed an improvement in the anticancer activity against MDA MB 231 cell line.
