Alkaloids of Jasminum species (family Oleaceae). II. Isolation of a new monoterpenoid alkaloid and other constituents

Abstract

A new monoterpenoid alkaloid (VI), closely related to the alkaloid (VII) from Rauwolfia verticillata, has been isolated from a Jasminum species from New Guinea. The same Jasminum species contains a substance C₁₁H₁₆O₅ for which the probable structure (IX) has been assigned from a study of its 100-Mc/s N.M.R. spectrum. The lignan pinoresinol has been isolated from the Queensland species Jasminum simplicifolium Forst.
