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.
