• the guests. This was explained by the enhanced flexibility of the non-closed rings. Even the signs of enantiorecognition were observed for the chloropheniramine/hydroxypropyl maltohexaose system. Further studies are planned to help the deeper understanding of the interactions. Keywords: acyclodextrin

• ; cyclodextrin; ibuprofen; maltodextrin; maltoheptaose; maltohexaose; maltooctaose; Introduction The complexing ability of amylose to iodine and fatty acids is well known in the literature [1][2][3]. The question is raised whether the maltooligomers containing 6, 7, or 8 glucose units (G6, G7 and G8), derived

• CDs is 2–3 orders of magnitudes higher than that of the non-cyclic, open-chain analogs [5]. Both maltohexaose and maltoheptaose (G6 and G7) caused spectral changes for guests like p-cresol and methyl orange in the UV–vis region. They also found that using a CPK molecular model both G6 and G7 form a
