Phenylglycosides from the Stems of Spiraea prunifolia var. simpliciflora.

One new phenylglycoside, 1-hydroxy-3,4,5-trimethoxyphenyl-1-O-[6′-O-(4″-carboxy-1″ ,3″ ,5″ - trihydroxy)phenyl]-β-D-glucopyranoside ( 1), along with eight known ones, isosalicin ( 2), vanilloloside ( 3), (4-hydroxy-3,5-dimethoxyphenyl)methyl-β-D-glucopyranoside ( 4), crenatin ( 5), hydrageifolin I ( 6), tachioside ( 7), isotachioside ( 8), and koaburside ( 9), were isolated from the stems of Spiraea prunifolia var. simpliciflora. The chemical structures of these compounds were identified on the basis of spectroscopic data such as NMR, FAB-MS, and IR. All these compounds were isolated from this plant for the first time.
