To search for new and bioactive constituents from traditional Chinese medicines, a new steroidal saponin, named vernonioside G ( 1 ), was isolated from the roots of Vernonia cumingiana Benth. (Compositae). The structure of vernonioside G was elucidated using spectral methods, particularly two‐dimensional nuclear magnetic resonance analysis. Together with the new compound, eight known compounds were also isolated and identified from the roots of V. cumingiana , among which, VE‐1 ( 2 ) and 24‐methylenelanost‐9(11)‐en‐3β‐ol acetate ( 3 ) were assigned NMR data for the first time and compound 3 was obtained as a natural product from a plant for the first time.
