Objective: To study the chemical constituents of the chloroform portion of Ailanthus altissima. Method: The chloroform portion were 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: Six compounds were isolated from the chloroform portion. They were identified as betulinic acid (1)
α-amyrin (2)
6α-hydroxylup-20(29)-en-3-on-28-oic acid (3)
2α
3β-dihydroxyurs-12-en-28-oic acid (4)
β-sitosterol (5)
ursolic acid (6). Conclusion: Compounds 1
2
3
4 and 6 were isolated from this plant for the first time.
