Crysochroa fulgidissima (Bidan-beole, Spanish fly) is traditionally used as a crude drug and insecticide in the East Asia and Korea, respectively. This study investigated the effect of ethanol extract of C. fulgidissima on the NO production activity. The C. fulgidissima extract was a potent inducer of NO production in CPAE cells and a stimulator of endothelial nitric oxide synthase in a dose-dependent manner. This study also evaluated the anti-inflammatory activity of this extract by determining the level of ICAM-1, VCAM-1, and prostaglandin $E_2$ from HUVEC cells. Although C. fulgidissima extract was a potent inducer of NO production in the CPAE cells, it showed weak inhibitory effects on vascular endothelial growth factor (VEGF) production in HUVEC cells. HPLC and GC-MS analysis of the ethanol extract of C. fulgidissima revealed the presence of cantharidin.
