Abstract: Eight compounds were isolated from the methanol extract of the roots and aerial parts of Anemone rivularis Buch.-Ham. ex DC. By means of spectroscopic methods, their structures were established as oleanolic acid 3 O α Larabinopyranoside(1), oleanolic acid 3-O-α-Lrhamnopyranosyl(1→2) α-Larabinopyranoside(2), oleanolic acid 3-O-α-Dribopyranosyl(1→3) α-Lrhamnopyranosyl(1→2) α-Larabinopyranoside(3), hederaginin 3 O-α-Larabinopyranoside(4), 3-O-α-Dribopyranosyl(1→3) α-Lrhamnopyranosyl(1→2) α-Larabinopyranosly oleanolic acid 28 O-α-Lrhamnopyranosyl(1→4) β-Dglucopyranosyl(1→6) β-Dgulcopyranoside(5), 3-O-α-Dribopyranosyl(1→3) α-Lrhamnopyranosyl(1→2) α-Larabinopyranosly hederaginin 28 O-Lrhamnopyranosyl(1→4) β-Dglucopyranosyl(1→6) β-Dgulcopyranoside(6), 3β,12β,23-trihydroxy olean 28,13 β-olide(7) and 3β,12β,13β-trihydroxy olean 28 oic acid 3-O-Dribopyranosyl(1→3) α-Lrhamnopyranosyl(1→2) α-Larabinopyranoside(8)-respectively. The last two compounds were new ones and named anemonolide(7) and anemoside B(8).
