Description:
Two new natural products, i.e. , 1- O ,2- O -[(1 S ,2 S )-1-(3-acetyl-2,4,6-trihydroxyphenyl)-3-hydroxypropane-1,3-diyl]- β - D -glucopyranose (=tomentoside I; 1 ) and (3 β )-3-(acetyloxy)ferruginol 12-[6- O -(4-hydroxy-3,5-dimethoxybenzoyl)- β - 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 1 H-, 13 C-, and 2D-NMR and HR-MS, as well as by chemical methods and comparison with literature data.
