Abstract
The chemical investigation of the roots of Lindera glauca guided the isolation and identification of three new sesquiterpenoids, namly glaucatotones J-L (1-3), and one known congener, (1β,5β)-1-hydroxyguaia-4(15),11(13)-dieno-12,5-lactone (4). The structures of new compounds were established based on comprehensive spectrographic methods, mainly including 1D & 2D NMR and HRESIMS analyses, and the absolute configurations were further confirmed by the comparison of experimental and calculated electronic circular dichroism (ECD). The cytotoxicity activities of isolates were evaluated, and the results showed that they have moderate cytotoxic activities.
