Difference in formation mechanism of inclusion complex between configuration isomers of gallate-type catechin and β-cyclodextrin
The formation mechanism of inclusion complex between (-)-epigallocatechin gallate (EGCg), which is the main catechin in tea leaves, or (-)-gallocatechin gallate (GCg), which is an isomer of EGCg, and β-cyclode...

Effect of solution pH on complex formation between epi-type catechin and β-cyclodextrin
The effect of solution pH on the formation of an inclusion complex between (−)-epigallocatechin gallate (EGCg: pKa = 7.5) and β-cyclodextrin (β-CD) was investigated by isothermal titration calorimetry and 1H-NMR ...

Improving water solubility of nateglinide by complexation of β-cyclodextrin
Inclusion complex of anionic nateglinide (NTG) with β-cyclodextrin (βCD) has been prepared to improve the water solubility of NTG. The mechanism of the complexation was elucidated using isothermal titration ca...
