Objective:To investigate the chemical constituents of Celastrus vamotii.Method:The air-dried roots and stems of C.vamotii were powdered and refluxed with 95% EtOH for three times.The combined extract were evaporation under reduced pressure to give residue
which was suspended in water and fractionated with ethyl acetate.Result: Five compounds were isolated from the EtOAc fraction and identified on basis of spectral and chemical evidence such as MS
1H-NMR
and 13C-NMR etc.They are β-sitosterol(1)
β-amyrin(2)
β-amyrin acetate(3)
30-hydroxylup-20(29)-en-3-one(4)
and 3-oxolup-20-(29)-en-30-al(5).Conclusion: All com-pounds were isolated from the plant for the first time.
