Anthocyanin Pigments of Three Y-Grape Strains Backcrossed by Vitis vinifera Varieties

Studies on Anthocyanin Pigments in Fruits Harvested in Japan. Part 8

Abstract

The anthocyanins isolated from three Y-grape strains, Y-3784, Y-4689 and Y-4708 (Fuefuki) by column chromatography on polyvinylpyrolidone, were identified with chromatographic techniques, hydrolysis methods and spectrometry.
(1) The total anthocyanin contents were very small, such as Y-3784; 4.7, Y-4689; 5.3 and Y-4708; 2.1mg/g in dried skins, respectively.
(2) The three grape strains contained 3-monoglucosides of malvidin and peonidin, and these monoglucosides acylated with p-coumaric acid.
(3) This results showed that 3-monoglucoside pigments are only contained in these strains backcrossed by Vitis vinifera in twice to hybrids (American species×V. vinifera).
