Mechanism of formation of “guest-host” complexes
between rutin and 2-hydroxypropyl-beta-cyclodextrin
Abstract
Abstract. ATR-FTIR
and NMR spectroscopy were used to investigate the mechanism of plant
antioxidants’ interactions with 2-hydroxypropyl-beta-cyclodextrin, using rutin
as an example. Rutin is characterized by the aromatic skeleton’s incorporation
into the cyclodextrin torus and stabilization brought about by the interaction
between the cyclodextrin’s –OH groups and the carbohydrate moiety.
Key words:
host-guest complexes, antioxidants, cyclodextrin, IR spectroscopy
