Four flavonoid glycosides, flavaprin (7), evodioside B (8), vitexin (11), and hesperidin (12), as well as the coumarins bergapten (1), xanthotoxin (2), and isopimpinellin (3), the lignan simplexoside (10), the steroids b-sitosterol (4) and daucosterol (5), the limonoids isolimonexic acid (6) and limonin (9), and uracil (13) and myo-inositol (14) have been isolated from Euodia daniellii. The structures of these compounds were established from spectral data. Among the isolates, bergapten showed cyclooxygenase-2 inhibitory activity with an IC50 value of 6.2 mg/ml. Flavonoids isolated from this plant exhibited no cytotoxic activity against the human tumor cell lines, A549, SKOV-3, SKMEL-2, XF498, and HCT15.
