The 13C NMR signals of D:A-friedo-olean-7-one, putranjivadione, D:A-friedo-olean-22-one, D:A-friedo-olean-3,22-dione, and Salacia triterpene R have been assigned using off-resonance decoupling and lanthanide induced shift techniques. 13C NMR data provide further evidence for the boat-boat conformation for the D and E rings of D:A-friedo-oleananes in solution.
