摘要
Two new 1-(6'-O-acyl-beta-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-beta-D-glucopyranosylpyridinium-3-carboxylate. (C) 2014 Jian-Gong Shi.
