TL;DR: In this article, eleven indole alkaloids, alstoniascholarines A-K (1-11), along with one known analogue, were isolated from the aqueous fraction of Alstonia scholaris leaf extract.

TL;DR: Six new indole alkaloids, named alstoniascholarines L–Q (1–6), together with nineteen known analogues were isolated from the inadequately dried leaves of Alstonia scholaris and their structures were elucidated on the basis of extensive analysis of spectroscopic data.

TL;DR: Alstonia scholaris F (1), a monoterpenoid indole alkaloid pigment with unprecedented carbon skeleton, and alstoscholarisine G (2) incorporated with a third nitrogen atom were isolated from the long-term stored leaves of Alstonia scholarsis as discussed by the authors.

TL;DR: In this paper, nine new indole alkaloids, vinmajines A-I (1-9), and 43 known indole alkaloids were isolated from cultivated Vinca major in Kunming.

TL;DR: Eight new C-21 pregnane glycoside ecdysosides A-H (1-8) were isolated from the stem of Ecdysanthera rosea and their structures were elucidated based on extensive spectroscopic data, as well as comparison with the reported literature data.
