Four new oleanane triterpene saponins were isolated and purified from the whole plant of Clinopodium urticifolium. They were 3B 16B, 23, 28-tetrahydroxyoleana-9 (11), 12(13)-diene-3-yl-[B-D-glucopyranosyl-(1-2)]-[B-D-glucopyranosyl-(1-3)]- B-D-fucopyranoside 1; 3B, 16B, 21B, 23, 28-pentahydroxyoleana-9(11), 12(13)-diene-3-yl-[B-D-glucopyranosyl-(1-2)]-[B-D-glucopyranosyl-(1-3)]- B-D-fucopyranoside 2; 3B, 16B, 23, 28-tetrahydroxyoleana-9(11), 12(13)-diene-3-yl-[B-D-glucopyranosyl-(1-6)-B-D-glucopyranosyl-(1-3)]-[B-D-glucopyranosyl-(1-2)]-B-D-fucopyranoside 3; 3B, 16B, 23, 28-tetrahydroxyoleana-9(11), 12(13)-diene-3-yl-[B-D-gluco-pyranosyl-(1-4)-B-D-glucopyranosyl-(1-6)-B-D-glucopyranosyl-(1-3)]-[B-D-glucopyranosyl-(1-2)]- B-D-fucopyranoside 4. Their structures were elucidated on the basis of interpretation of NMR and MS data and from chemical evidence.
