The triterpene fractions of the dried roots of Potentilla tormentilla
were investigated and three new compounds were isolated. The new struc
tures were established by detailed nmr spectral studies as 3 alpha,19
alpha-dihydroxyurs-12-en-28-oic acid-(28-->1)-beta-D-glucopyranosyl es
ter [1], 2 alpha,3 beta-dihydroxyurs-12-en-28-oic acid-(28-->1)-beta-D
-glucopyranosyl ester [2], and 3 beta,19 alpha-dihydroxyolean-12-en-28
-oic acid-(28-->1)-beta-D-glucopyranosyl est er [3].
