A new flavonoid, 7,3ˊ-dihydroxy-3,5,4ˊ-trimethoxy flavone, along with two known flavonoids, 7-hydroxy-5,4ˊ-dimethoxyflavone and 7-hydroxy-3,5,4ˊ-trimethoxy flavone were isolated from the leaves ethyl acetate extract of Eusideroxylon zwageri Teijsm. & Binn. (Lauraceae). Structures were elucidated by spectroscopic techniques such as NMR, IR, and Orbitrap Mass Spectrometry.
