Abstract

Five new oleanane-type triterpene glycosides named strogins 1-5 were isolated from leaves of Staurogyne merguensis. Their structures were determined on the basis of chemical and spectral evidence. After strogins 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 relationship is discussed.

摘要

从滨海叉柱花的叶子中分离出了五种新的齐墩果烷型三萜糖苷，命名为strogins 1 - 5。它们的结构是根据化学和光谱证据确定的。将strogins 1、2和4含在口中后，水会引发甜味。另一方面，strogins 3和5没有这种活性。本文讨论了构效关系。
