%X from the leaves of ilex brevicuspis were isolated a new triterpene, 20(s)-3¦Â, 19¦Á-dihydroxyurs-12-en-23, 28-dioic acid, named here brevicuspic acid, and two new triterpenoid glycosides, 3-o-¦Á-larabinopyranosyl-20(s)-pomolic acid-28-o-¦Â-d-glucopyranosyl ester, named brevicuspisaponin 3, and the 23-sodium salt of (20s)3¦Â, 19¦Á, 24-trihydroxyurs-12-en-23, 28-dioic acid-28¦Â-o-¦Â-dglucopyranosyl ester, along with the known compound 3-o-¦Á-larabinopyranosyl-20(s)-19¦Á, 24-dihydroxyursolic acid- 28-o-¦Â-dglucopyranosyl ester, already described for ilex argentina. their structures were established on the basis of chemical and spectroscopic methods.
