RESUMEN
OBJECTIVE: To study the coumarins from Mallotus conspurcatus. METHODS: The ethyl acetate part of 75% ethanol extracts from Mallotus conspurcatus was isolated. The compounds were isolated and purified with column chromatography, and their structures were elucidated on the basis of 1H-NMR, 13C-NMR and ESI-MS data. RESULTS: Twelve coumarins were determined to be malloapelin A (1), 5'-demethyl aquillochin (2), aquillochin (3), cleomiscosin B (4), 6-hydroxy-7-methoxy-coumarin (5), braylin (6), aegelinol (7), bergapten (8), isofraxidin (9), fraxidin (10), grevillone (11), and fraxetin (12). CONCLUSION: Compounds 6-12 are isolated from this genus for the first time.
