Indole Alkaloids from the Leaves of Alstonia scholaris
摘要:
A new indole alkaloid, akuammidine-N-oxide (1) was isolated from the leaves of Alstonia scholaris (Apocynaceae) together with akuammidine (2), and the structure was elucidated by NMR spectral analysis and chemical correlation. Akuammidine (2) showed a moderate antiplasmodial activity.
