Abstract
Five new oleanane-type triterpene glycosides named strogins 1-5 were i solated from leaves of Staurogyne merguensis. Their structures were de termined on the basis of chemical and spectral evidence. After strogin s 1, 2 and 4 were held in mouth, water elicited a sweet taste. On the other hand, strogins 3 and 5 had no activity. The structure-activity r elationship is discussed.
