ABSTRACT
Objective:
To study the chemical constituents in the twigs and leaves of Ervatamia officinalis.Methods:
The chemical constituents were isolated from the total alkaloids of the twigs and leaves of Ervatamia officinalis by using silica gel, ODS, Sephadex LH-20, and HPLC. The chemical structures of the compounds were identified based on their physical and chemical properties and spectroscopic methods.Results:
Fourteen alkaloids were isolated and identified as 7S-coronaridine hydroxyindolenine (1), 7S-voacangine hydroxyindolenine (2), coronaridine (3), 19S-heyneanine (4), voacangine (5), tabernaemontanine (6), dregamine (7), 3-(2-oxopropyl) coronaridine (8), 3-oxovoacangine (9), voastrictine (10), 16R,19E-isositsirikine (11), 16R,19Z-isositsirikine (12), 16R,19E-isositsirikine N4-oxide (13), and geissoschizol (14).Conclusion:
Compounds 8-14 are obtained from this plant for the first time.
