In the previous paper, the authors have reported on the white precipitates found in syrup of canned Iyo orange segments which had been prepared by addition of β-cyclodextrin (β-CD) or Dexyparl K-100 (α-CD rich CD formula) and presumed that those precipitates may be inclusion compounds of CD with components of juice sac membrane. This report dealt with the identification of acidic and neutral fractions of guest compounds included in those inclusion compounds. After hydrolyzing the CD moiety of them, guest components were extracted and analyzed by means of thin layer chromatography and gas chromatography. The guest compounds of β-CD inclusion compound were fatty acids, sterols and sterol esters. The K-100 inclusion compound was found to be α-CD inclusion compound and the guest compounds of it were fatty acids, whereas no sterols and their esters were recognized in it. Limonin and/or nomilin were also not detected in those inclusion compounds.
