Structural Elucidation of Tectoruside Isolated from Iris tectorum Maxim. by NMR Spectroscopy

Abstract

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.

Key words: NMR, assignment, 1{3′methoxy4′\[OβDglucopyranosyl (1→6)βDglucopyranosyl\]phenyl}ethanone, Tectoruside, Iris tectorum Maxim
