Content of isoXavones in yogurt
The contents of isoXavones in GABA soya milk were
determined by HPLC (Waters) as described by Wang et al.
(2003) with minor modiWcations (Kim et al., 2004). IsoXavones
were extracted as described by Kim et al. (2004). IsoXavone
contents were calculated from standard calibration
curves generated by using standard genistein, daidzein and
glycitein.
