Using a high-performance liquid chromatography (HPLC) technique, the avenacoside A and B content was determined in 16 oat cultivars and in four fractions of oat kernel. The saponin content was significantly different (P<0.05) between the oat cultivars and ranged from 0.020 to 0.050% with a mean of 0.040% (dry matter basis). There was no significant correlation between lipid and saponin content. Milled oat kernels were separated into fractions according to particle size. The fractions with the smallest particle sizes had the highest concentrations of saponins. Thus, the oat kernel saponins seem to be situated mainly in the endosperm.
