Acetophenone glycosides from thyme (Thymus vulgaris L.)
Journal of Agricultural and Food Chemistry 47(5) (1999)
1911-1914
Four acetophenone glycosides were isolated from the butanol-soluble fraction of thyme extracts. Their structures were determined by spectral methods (MS, NMR, and 2D-NMR). Among them, two new compounds, 4-hydroxyacetophenone 4-O-[5-O-(3,5-dimethoxy-4-hydroxybenzoyl)-β-D-apiofuranosyl]-(1→2)-β-D-glucopyranoside (1) and 4-hydroxyacetophenone 4-O-[5-O-(4-hydroxybenzoyl)-β-D-apiofuranosyl]-(1→2)-β-D-glucopyranoside (2), were determined. Compound 1 showed weak cytotoxicity, inhibiting DNA synthesis of human leukemia cells.
