S. Valcic et al., TRITERPENOIDS FROM ACAENA-PINNATIFIDA R ET P, Zeitschrift fur Naturforschung. C, A journal of biosciences, 52(3-4), 1997, pp. 264-266
Eight urs-12-ene triterpenoids, beta-sitosterol, (+)-catechin, and api
genin 7-O-glucoside were isolated from the leaves of Acaena pinnatifid
a R. et P. The triterpenoids were characterized as pomolic acid, pomol
ic acid-3-acetate, tormentic acid, 2-epi-tormentic acid, euscaphic aci
d, tormentic acid glucoside, niga-ichigoside F1, and niga-ichigoside F
