OBJECTIVE To study the chemical constituents of the flower of Paulownia fortunei. METHODS The constituents were isolated by column chromatography and their structures were elucidated through spectroscopic analysis. RESULTS The compounds were identified as: apigenin (I), luteolin (II), Hesperetin (III), Naringenin-7-O-beta-D-glucoside (IV), Arbutin (V), 4-hydroxybenzyl-beta-D-glucoside (VI), abscisic acid (VII) and 1-acetoxy-3-hydroxypropan-2-yl-3-hydroxypentanoate (VIII).
