The solid-phase extraction (SPE) of steroids involving formation of their inclusion complexes with P-CD polymer has been investigated [27, 28], SPE based on hydrophobic interaction is widely used, however for steroids a new SPE technique based on the formation of inclusion complexes with P-CD has been developed. This technique has been applied for comprehensive sample purification of 45 endogenous or synthetic androgens, 11 endogenous estrogens and 21 corticoids for MS analysis [29],...
