Extraction of the aerial parts of Ophiorrhiza major Ridl. has yielded a new C19 pentacyclic quaternary indole alkaloid, ophiorrhizine.The structure was established as 1 on the grounds of its spectral properties (optical rotation) and its X-ray molecular structure.Its biosynthetic relationship to the Cinchona alkaloids is discussed.
