ABSTRACT
From the leaves of Ilex brevicuspis were isolated a new triterpene, 20(S)-3"BETA", 19"ALFA"-dihydroxyurs-12-en-23,28-dioic acid, named here brevicuspic acid, and two new triterpenoid glycosides, 3-O-"ALFA"-L-arabinopyranosyl-20(S)-pomolic acid-28-O-"BETA"-D-glucopyranosyl ester; named brevicuspisaponin 3, and the 23-sodium salt of (20S)- 3"BETA", 19"ALFA", 24-trihydroxyurs-12-en-23,28-dioic acid-28"BETA"-O-"BETA"-D-glucopyranosyl ester; along with the known compound 3-O-"ALFA"-L-arabinopyranosyl-20(S)-19"ALFA",24-dihydroxyursolic acid- 28-O-"BETA"-D-glucopyranosyl ester; already described for Ilex argentina. Their structures were established on the basis of chemical and spectroscopic methods...
