To study the chemical constituents of the flower of Paulownia fortunei (Seem.) Hemsl.
The constituents were isolated by column chromatography and their structures were elucidated through spectroscopic analysis.
The compounds were identified as diplacone(I) ,3 '-O-methyldiplacone (II) , mimulone (ll) , ursolic acid(IV), beta-sitosterol (V), daucosterol (VI).
All these compounds were obtained from the flower for the first time.
