Objective To study the chemical constituents in the seeds of Datura metel. Methods The constituents were isolated and purified by silica gel, ODS, and Sephadex LH-20 column chromatographies as well as HPLC. Their chemical structures were elucidated on the basis of spectral data. Results The compounds were isolated from the EtOAc fraction of D. metel extract and identified as cannabisin D (1), cannabisin E (2), cis-cannabisin E (3), cannabisin F (4), cannabisin L (5), cannabisin G (6), grossamide K (7), hyoscyamilactol (8), daturaolone (9), N-trans-feruloyl tryptamine (10), and fraxetin (11), respectively. Conclusion Compounds 2 and 4 are firstly isolated from the plants in Solanaceae, compounds 1, 3, and 5-7 are firstly isolated from the plants in genus Datura L. and compounds 8-11 are isolated from this plant for the first time.
