ABSTRACT
Objective:
To develop a method for separation and purification of triterpenoids from Helicteres angustifolia by highspeed countercurrent chromatography( HSCCC).Methods:
The ethyl acetate extract of Helicteres angustifolia were separated by two-step HSCCC. The structures of the target compounds were identified by ESI-MS and1H-NMR and characterized by FTIR.Results:
Six compounds were isolated and prepared from ethyl acetate extract of Helicteres angustifolia,and identified as methyl helicterilate( 1),methyl helicterate( 2),helicterilic acid( 3),helicteric acid( 4),betulic acid( 5),oleanolic acid( 6). The purity of the chemical constituents were determined by HPLC,and the mass fraction was more than 95. 0%,respectively.Conclusion:
This method is suitable for the separation and preparation of triterpenoids from Helicteres angustifolia,which is rapid,high purity and high yield.
