Abstract
The anticariogenic activity extractable from oat hulls was found to be associated with the acidic fraction of the ether-solubles. This fraction contained fatty acids, several phenolic acids and three poly phenols. Neither the fatty acids (palmitic and oleic), nor the phenolic acids gave any reduction in caries when tested individually. A correlation between the polyphenols and the anticariogenic activity was found. Three polyphenols were identified as the following flavonoids: tricin, homoeriodicytol and the chalcone of homoerio-dictyol.
