Abstract
Two saponins and a sapogenin were isolated from the leaves of Ilex brevicus pis. Their structures were established by means of spectroscopic methods as brevicuspisaponin 1 (3-O-alpha-L-arabinopyrnnosyl-2D(S)-19 alpha,24- acid) , brevicuspisaponin 2 (3-O-alpha-L-arnbinopyranosyl-20( S)- 19 alpha,23,14- trihydroxyursolic acid) and 23-methylester or 20(S)-3 beta.19 alpha,24-hydr oxyurs-12-en-23,28-dioic acid.
