Abstract
SEVERAL polyphenols have been found to be accumulated in the sound part next to the injured tissues of sweet potato attacked by black rot caused by Ceratostomella fimbriata, and chlorogenic acid, caffeic acid and isochlorogenic acid have been isolated as well as the two kinds of new caffeic acid derivatives. Previously, G. O. Rudkin and J. M. Nelson1 had isolated chlorogenic acid and a group of components giving caffeic acid by alkaline hydrolysis from sound sweet potato.
