Alkaloids from the Fruits of Stephania japonica MIERS. I. Structure of Stephabenine : A New Hasubanan Ester-Ketal Alkaloid
A new hasubanan ester-ketal alkaloid, named stephabenine, was isolated from the fresh fruits of Stephania japnica MIERS (Menispermaceae). Alkaline hydrolysis of the new base gave benzoic acid and a basic component, whose proton nuclear magnetic resonance spectrum was identical with that of authentic...

Zusammenfassung: | A new hasubanan ester-ketal alkaloid, named stephabenine, was isolated from the fresh fruits of Stephania japnica MIERS (Menispermaceae). Alkaline hydrolysis of the new base gave benzoic acid and a basic component, whose proton nuclear magnetic resonance spectrum was identical with that of authentic N, O-dimethylstephine. |
