Abstract:
Objective To study indole alkaloids of Ervatamia hainanensis. Methods The compounds were separated and purified by column chromatography with silica gel and Sephadex LH-20. The structures were identified by IR, MS, and NMR. Results Seven alkaloids were identified as: hainanervatasine (Ⅰ), hainanervatacine (Ⅱ), vobasine (Ⅲ), coronaridine (Ⅳ), 3-hydroxyl coronaridine (Ⅴ), 3-(2-oxopropyl) coronaridine (Ⅵ), and tabernamine (Ⅶ), respectively. Conclusion Compounds Ⅰ and Ⅱ are new compounds. Compounds Ⅳ and Ⅵ are isolated from this plant for the first time.
