OBJECTIVE
To study the chemical constituents of leaves of Paulownia fortunei (Seem.) Hemsl.
METHODS
The constituents were isolated by column chromatography and their structures were elucidated through spectroscopic analysis.
RESULTS
The compounds were identified as mimulone (I), apigenin (II), luteolin (III), 2alpha, 3beta, 19beta-trihydroxyurs-28-O-beta-D-galactonopyranos ylester (anserinoside, IV), 3alpha-hydroxyl-ursolicacid (V), ursolicacid (VI), daucosterol (VII), beta-sitosterol (VIII).
CONCLUSION
The compounds I - V are obtained from leaves of Paulownia fortunei (Seem.) Hemsl for the first time.
