Phytochemical investigation of Acanthus montanus has resulted in the isolation of novel pentacyclic triterpenoids, urs-12-ene-3-α-L-rhamnopyranosyl(28→1)-β-D-glucopyranosylester 1, urs-12-en-28-oic acid-3-O-β-D-glucopyranosyl(1→2)-β-D-glucopyranoside 2 and 3β,24-dihydroxyolean-12-en-28-oic acid 3. Their structures have been established by spectroscopic studies.
