[Studies on the chemical constituents from flower of Paulownia fortunei].
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).


CONCLUSIONS
All these compounds are obtained from the flower of this plant for the first time.
