Two new bioactive oleanane triterpene glycosides from Terminalia arjuna.

Academic Article


  • Two new oleanane-type triterpene glycosides designated as Termiarjunoside I and Termiarjunoside II were isolated from stem bark of Terminalia arjuna (Combretaceae) and characterized as olean-1alpha,3beta,9alpha,22alpha-tetraol-12-en-28-oic acid-3beta-D-glucopyranoside (1) and olean-3alpha,5alpha,25-triol-12-en-23,28-dioic acid-3alpha-D-glucopyranoside (2) based on chemical and spectral data evidences. Both compounds 1 and 2 potently suppressed the release of nitric oxide and superoxide from macrophages and also inhibited aggregation of platelets.
