Chemical constituents from the water-soluble fraction of wild Sargentodoxa cuneata

AimTo study the chemical constituents from the water-soluble fraction of wild Sargentodoxa cuneata.MethodsThe compounds were isolated by silica gel and HW-40C column chromatography. Their structures were elucidated on the basis of spectral analysis of ESI-MS and NMR.ResultsEight known glycosides were isolated and identified as (−)-lyoniresinol-9-O-β-D-glucoside (1), (+)-lyoniresinol-9-O-β-D-glucoside (2), (−)-lyoniresinol-9′-O-β-D-glucoside (3), (+)-syringaresinol-4-O-β-D-glucoside (4), androsin (5), (+)-syringin (6), sargentol (7) and daucosterol (8).ConclusionCompounds 1, 3 and 6 were isolated from this plant for the first time, and constituents of the water-soluble parts of wild S. cuneata were studied systematically for the first time.
