5-Hydroxydictamnine, a new alkaloid from Atalantia monophylla

Abstract

A new furoquinoline alkaloid, 5-hydroxydictamnine, along with β-sitosterol was isolated from the heartwood of Atalantia monophylla. The structure of this alkaloid was established by chemical and spectral evidences together with a nuclear overhauser effect (NOE) experiment.
