摘要:

采用95 %乙醇提取,硅胶柱层析,以及重结晶等方法从川射干中分离其化学成分,并通过各种光谱进行结构鉴定. 从川射干正丁醇部位分离得到一个酚二糖苷类化合物点地双梅糖苷(Tectoruside),通过包括2D NMR在内的各种光谱首次阐明了它的结构,归属了所有碳与氢的化学位移,其结构为1-{3′-甲氧基-4′-[O-β-D-吡喃葡萄糖基(1→6)-β-D-吡喃葡萄糖基\]苯基}乙酮.

Abstract:

The chemical constituents of Iris tectorum Maxim. were extracted with 95% alcohol, isolated by column chromatography on silica gel, and purified by recrystallization. The structures of the compounds were analyzed on the basis of the spectral data. A phenolic diglycoside, Tectoruside, was isolated from the n-Butanol portion of the extract, and its structure was elucidated by various spectroscopic data, including 2D NMR. The 1H and 13C NMR chemical shifts of the compounds were assigned. Its structure was found to be 1-{3′-methoxy-4′-[O-β-D-glucopyranosyl (1→6)-β-D-glucopyranosyl\]phenyl}ethanone.
