Abstract

A new alkaloid, oxypterine, was isolated from Lotononis oxyptera. It was also detected in related species of the subsection Rostrata. The structure consists of an azacyclooctane ring with methylene, chloro and chloromethylene substituents. Mass spectrometry and 1D and 2D NMR experiments were used in the structural analysis of the new product.
