Resumo
Two new triterpenoid glycosides, quinovic acid-3 beta-O-beta-D- glucopyranosyl-(1-->4)-alpha-L-rhamnopyranoside and quinovic acid-3 beta-O-beta-D-glucopyranosyl-(1-->3)-beta-D-fucopyranoside (named rubelloside A and B, respectively), were isolated from roots of Adina rubella. Their structures were elucidated by spectral and chemical means. Rubelloside B exhibited immunological enhancement.
