Triterpenoids from the Roots of Rhaphiolepis indica var. tashiroi and Their Anti-Inflammatory Activity

Two new triterpenoids, 2α,3β-dihydroxyolean-11,13(18)-dien-19β,28-olide (1) and 3β,5β-dihydroxyglutinol (2), together with eight known compounds (3–10) were isolated from the roots of Rhaphiolepis indica var. tashiroi (Rosaceae). The structures of 1–10 were determined by spectroscopic techniques. Am...

Sumario:Two new triterpenoids, 2α,3β-dihydroxyolean-11,13(18)-dien-19β,28-olide (1) and 3β,5β-dihydroxyglutinol (2), together with eight known compounds (3–10) were isolated from the roots of Rhaphiolepis indica var. tashiroi (Rosaceae). The structures of 1–10 were determined by spectroscopic techniques. Among these isolates, 2α,3β-dihydroxyolean-13(18)-en-28-oic acid (9) exhibited inhibitory effect on N-formyl-methionyl-leucyl-phenylalanine (fMLP)-induced superoxide production, with an IC(50) value of 16.50 μM.
