title: Three novel β-carboline alkaloids from Gelsemium elegans.
abstract: Three novel β-carboline alkaloids characterized with a unique degraded monoterpenoid moiety, gelebolines A-C (1-3), together with 11 known alkaloids of different types, were isolated from the roots of Gelsemium elegans. The structures of new alkaloids were established on the basis of analysis of spectroscopic data. It is the first example for report of β-carboline from genus Gelsemium (Loganiaceae).
