Abstract

A new cadinane sesquiterpenoid glucoside, 2β,7,3-trihydroxycalamenene 3-O-β-d-glucoside (1) together with six known compounds, N-(p-trans-coumaroyl)-N-methyl tyramine (2), Cleomiscosin A (3), 9,12,13-trihydroxy-10,15-heptadecadienoic acid (4), Cytochalasin B (5), Marmesinin (6) and N-(p-trans-coumaroyl) tyramine (7) were obtained from the stem bark of Abelmoschus sagittifolius. The new structure of compound 1 was elucidated by analysing its 1H and 13C-NMR, 1H-1H COSY, HSQC, HMBC, NOESY and HR-ESI-MS spectra. Compounds 1–7 showed moderate cytotoxicity against Hela and HepG-2 human cancer cell lines.
