Modification of Extracting Procedure for Tenuazonic Acid from Cereals and Determination by HPLC with Photodiode Array UV Detection

Abstract

A modified method for extracting tenuazonic acid (TA) from cereals and rice culture was developed. The method gave a distinct increase in TA concentration in comparison with the published one, at an average of 6.1 and 1.8 times higher for weathered wheat and rice culture materials of Alternaria alternata, respectively. It will be applicable to extract low levels of TA from cereals.
