A new coumaronochromone,6,4'-dihydroxy-7,5'-dimethoxy-coumaronochromone (1), together with eleven known flavonoids (2-12) were isolated from the ethanol extract of the aerial part of Derris elliptica. Their structures were elucidated on the basis of spectroscopic analysis. Compounds 2, 4, 7,8 and 9 exhibited moderate insecticidal activities against larvae of Aedes albopictus. All compounds showed strong cytotoxic activities against Spodoptera litura (SL) and Trichoplusia ni BTI-Tn-5B1-4 (Hi-5) cells comparison to positive control of rotenone. (C) 2012 Elsevier B.V.
