From the whole plant of Stauntonia hexaphylla, a new phenolic glycoside, staunoside F, was isolated along with six triterpenoids: 3-hydroxy-30- norolean-12,20(29)-dien-28-oic acid, oleanolic acid, hederagenin, lupeol, betulonic acid and betulinic acid. The phenolic glycoside was characterized by 1D- and 2D-NMR techniques. The biogenetic relationship of 30- nortriterpenoids with an exocyclic double bond at C-20(29) is briefly discussed.
