Minor diterpenoid glycosides from the leaves of Stevia rebaudiana

► Twelve diterpenoid glycosides, including three new compounds (1-3) were isolated from the leaves of Stevia rebaudiana. Among them, 2-4 are ent-kaurene diterpenoids with a 15,16-double bond whereas 1 has the 16,17-double bond common to steviol glycosides. The discovery of these compounds is an important addition in expanding our understanding of the diversity of the diterpenoid glycosides present in the S. rebaudiana.
