Abstract

The major anthocyanins of boysenberry fruit, a cross between Rubus loganbaccus and Rubus baileyanus Britt., were isolated by preparative high-performance liquid chromatography (HPLC). The structures of cyanidin-3-[2-(glucosyl)glucoside] (1) and cyanidin-3-[2-(glucosyl)-6-(rhamnosyl)glucoside] (2) were determined by NMR in 1% DCOOD/D(2)O. An unusually high chemical shift (delta 2.5) is reported for H-5' '' of cyanidin-3-[2-(glucosyl)glucoside].
