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].

摘要

杂交黑莓果实（由罗甘莓和贝利氏悬钩子杂交而成）的主要花青素通过制备型高效液相色谱法（HPLC）进行分离。矢车菊素 - 3 - [2 - （葡萄糖基）葡萄糖苷]（1）和矢车菊素 - 3 - [2 - （葡萄糖基） - 6 - （鼠李糖基）葡萄糖苷]（2）的结构通过在1%DCOOD/D₂O中的核磁共振（NMR）测定。据报道，矢车菊素 - 3 - [2 - （葡萄糖基）葡萄糖苷]的H - 5'''具有异常高的化学位移（δ 2.5）。
