New triterpene and triterpenoid glycosides from Ilex brevicuspis

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