Objective:To study the chemical constituents of the butanol portion of Ailanthus altissima. Method: The butanol portion was isolated and purified by silica gel column chromatography
HP-20 and Sephadex LH-20. Their chemical structures were elucidated by spectral data (1H-NMR
13C-NMR). Result: Five compounds were isolated from the butanol portion. They were identified as betulin ( 1 )
uvaol ( 2 )
betulinic acid ( 3 )
phaseic acid ( 4 )
1-O-(6-O-α-L-rhamnopyranosyl-β-D-glucopyranosyl)-4-allylbenzene( 5 ). Conclusion: Compounds 1-4 were isolated from this plant for the first time.
