Two 1-(6′-O-acyl-β-d-glucopyranosyl)pyridinium-3-carboxylates from the flower buds of Lonicera japonica

Two new 1-(6′-O-acyl-β-d-glucopyranosyl)pyridinium-3-carboxylates, lonijaponinicotinosides A (1) and B (2), were isolated from an aqueous extract of the flower buds of Lonicera japonica. Their structures were determined by spectroscopic data analysis, and confirmed by comparison with synthetic 1-β-d-glucopyranosylpyridinium-3-carboxylate.

Two new 1-(6′-O-acyl-β-d-glucopyranosyl)pyridinium-3-carboxylates, named lonijaponicotinosides A (1) and B (2), were isolated and characterized from an aqueous extract of the flower buds of Lonicera japonica.Figure optionsDownload as PowerPoint slide
