Abstract

Objective: To investigate the chemical constituents of Kalopanax septemlobus.

Methods: Chromatographic techniques including silica gel, gel, semi-preparative HPLC and PTLC as well as recrystallization were employed in the isolation and purification, and the structures were elucidated by spectral analysis and physical and chemical properties.

Results: 6 compounds were identified as liriodendrin (1), (-) -syringarenol (2), trans-coniferyl aldehyde (3), trans-caffeic acid (4), beta-daucosterol (5), beta-sitosterol (6).

Conclusion: Compounds 2 -5 are obtained from this genus for the first time.
