Abstract

A rearranged cadinane sesquiterpene glycoside named tinocordiside ( 1 ), consisting of a tricyclic skeleton with a cyclobutane ring, has been isolated from the immunomodulatory aqueous fraction of the Indian medicinal plant Tinospora cordifolia . The structure has been established by spectroscopic and chemical methods.
