摘要: 用2D NMR (1H-1H COSY和1H-13C COSY)技术研究了从鹰瓜花中分离到的黄酮醇-3-O-吡喃鼠李糖基呋喃阿拉伯糖甙的双糖结构,明确其双糖为1→2连接.

Abstract: This paper deals with the studies of 2D NMR spectra of disaccharidc moiety of a flavonol-3-O-α-L-rhamnopyranosyl-α-L arabofuranoside from the leaves of Artabotrys hexapetalus. The interlinkage of the biose was determined to be α-L-rhamnopyranosyl-(1→2)-α-L-arabofuranose.A simple NMR criterion was proposed for flavonol-3-O-rhamnopyranosyl (1 → 2)-arabofuranoside.

Key words: Flavonol-3-O-rhamnopyranosylarabofuranoside, Disaccharide structure, 2D NMR
