Abstract

Total amounts of phenolic compounds of Korean apples were determined by UV-visible spectrphotometry of Folin-Dennis, Prussian-blue and vanillin-HCI, respectively. The analytical data from the method of Folin-Dennis were estimated to be the most reasonable to determine the total amounts of phenolic compounds in Korean apples. It was also confirmed that the amounts of total phenolics could be calculated as chlorogenic acid equivalence, more effectively than that of other phenolic compound equivalence.
