OBJECTIVE
To investigate the chemical constituents of the rhizome of Ervatamia hainanensis.
METHODS
The solvent extraction and silica column chromatography were used to separate the chemical constituents, and their structures were identified by physico chemical properties and spectra analysis.
RESULTS
Twelve compounds were isolated and their structures were identified as voacangine (1), ibogaine (2), ibogamine (3), coronaridine (4), 19-heyneanine (5), 19-epi-heyneanine (6), 3-hydroxyl coronaridine (7), coronaridine hydroxyindolenine (8), 3-(2-oxopropyl) coronaridine (9), vobasine (10), alpha-amyrin (11), alpha-amyrin acetate (12).
CONCLUSIONS
Compounds 1, 2, 6, 11 and 12 were first found from this plant.
