Kaki tannin was isolated from methanol extracts of unripe kaki fruit (Japanese persimmon) and it was found that a main constituent composing kaki tannin was a leucoanthocyanin. Its acetate and methyl ether were prepared and their properties and reactions were studied. From the results of these experiments, kaki tannin was presumed to be a (+) leucodelphinidin-3-glucoside (5, 7, 3', 4', 5'-pentahydroxyflavan-3, 4-diol-3-glucoside).
