Alkaloids from <i>Cinnamomum Philippinense</i>

Abstract

A new pyridine, 2-(4'-hydroxypyridin-3'-yl)-acetic acid (1), along with five known alkaloids, cinnaretamine (2), crykonisine (3), corydaldine (4), glaziovine (5) and zenkerine (6), were isolated from the roots of Cinnamomum philippinense (Lauraceae). Their structures were characterized and identified by spectral analysis.
