A new sesquiterpenoid quinone, Acyl hibiscone B (1), together with five known compounds, (R)-lasiodiplodin (2), (R)-de- O -methyllasiodiplodin, (3) dibutyl phthalate (4), (R)-9-phenylnonan-2-ol (5) and hibiscone B (6), was obtained from the stem tuber of Abelmoschus sagittifolius . The structure of compound 1 was elucidated by analysing its ¹H and ¹³C NMR, ¹H- ¹H COSY, HSQC, HMBC, NOESY and HR-ESI-MS values. Compound 1 showed significant cytotoxicity against Hela and HepG-2 human cancer cell lines.
