Abstract:
Objective To study the chemical constituents from the roots of Aruncus sylvester. Methods The compounds were separated and purified by D101 macroporous resin, silica gel and ODS column chromatography. Their structures were elucidated by extensive spectroscopic methods including 1D and 2D NMR, HR-ESI-MS and ECD spectrum. Results Two new monoterpene glucosides were isolated from A. sylvester, and identified as (2E,4S,5R)-4-hydroxy-3-[2-(β-D-glucopyranosyloxy)ethylidene]- 5-(2-methylprop-1-en-1-yl) dihydrofuran-2(3H)-one (1) and (2Z,4S,5R)-4-hydroxy-3-[2-(β-D-glucopyranosyloxy) ethylidene]-5- (2-methylprop-1-en-1-yl) dihydrofuran-2 (3H)-one (2). Conclusion Compounds 1 and 2 are new compounds, and named as sylvesteroside A and sylvesteroside B, respectively.
