WebbEncapsulation of boswellic acid with β- and hydroxypropyl-β-cyclodextrin: Synthesis, characterization, in vitro drug release and molecular modelling studies WebbComplexing ability of 2-hydroxypropyl-β-cyclodextrin depends on the average substitution degree. For γ-cyclodextrin, hydrophobic interactions play the major role in binding the guest. The association of natural and modified β-cyclodextrins is ruled by van der Waals interactions and hydrogen bonding because of the tighter fit of the guest into the cavity.
