Two new polyoxygenated triterpenoids, (2 β ,3 α ,6 α )‐2,3,6,20,23,30‐hexahydroxyurs‐12‐en‐28‐oic acid ( 1 ) and (2 β ,3 α )‐2,3,20,23,24,30‐hexahydroxyurs‐12‐en‐28‐oic acid O ‐ β ‐ D ‐glucopyranosyl ester ( 2 ) were isolated from the roots of Actinidia valvata Dunn . Their structures were elucidated by means of extensive spectroscopic studies. Both compounds showed moderate cytotoxic activity in vitro against the BEL‐7402 and SMMC‐7721 tumor cell lines.
