Indole alkaloids from cultivated Vinca major

Nine new indole alkaloids, vinmajines A–I (1–9), and 43 known indole alkaloids were isolated from cultivated Vinca major in Kunming. The new structures were elucidated by extensive spectroscopic and quantum theory analysis. In addition, the results also supported that types of indole alkaloids from V. major might be influenced significantly by the ecological environment.
