GRAPHICAL ABSTRACT

ABSTRACT
A new germacrane-type sesquiterpenoid compound (1) and four known compounds (2-5) were isolated from Siegesbeckia orientalis. Chemical structures of these compounds were elucidated using 1D and 2D NMR spectroscopic data, HR-ESIMS, electronic circular dichroism (ECD) and compared with the literature. Their anti-proliferative effects were evaluated on human triple-negative breast cancer (TNBC) cell line MDA-MB-231. The results demonstrated that compound 2 significantly inhibits the proliferation of MDA-MB-231 cells by inducing apoptosis.
