摘　　要：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.Four new oleanane triterpene saponins were isolated and purified from the whole plant of Clinopodium urticifolium.
