Two Glycosides and Other Constituents from Anemone tomentosa Roots

Two new natural products, i.e., 1-O,2-O-[(1S,2S)-1-(3-acetyl-2,4,6-trihydroxyphenyl)-3-hydroxypropane-1,3-diyl]-beta-D-glucopyranose (= tomentoside I; 1) and (3 beta)-3-(acetyloxy) ferruginol 12-[6-O-(4-hydroxy-3,5-dimethoxybenzoyl)-beta-D-glucopyranoside] (= tomentoside II; 2), were isolated from the EtOH extract of the root of Anemone tomentosa, together with five known compounds. Their structures were characterized by means of spectroscopic methods, especially by H-1-, C-13-, and 2D-NMR and HR-MS, as well as by chemical methods and comparison with literature data.
