Abstract: | In this study, we prepared crude fibre samples from young fruits of 10 persimmon (Diospyros kaki) cultivars and from young fruits of Japanese pear (Pyrus pyrifolia var. culta) and peach (Prunus persica) and compared their bile acid-binding abilities in?vitro. All crude fibre samples from young fruits of persimmon were able to bind to cholic acid in a 4?mM cholic acid solution, but crude fibre samples from young fruits of Japanese pear and peach did not show bile acid-binding ability. The bile acid-binding ability was strongly correlated with the water-insoluble condensed tannins content in crude fibre samples (r?=?0.909, p?0.001). These results indicate that the water-insoluble condensed tannins content in young fruits of persimmon is related to its bile acid-binding ability. |
