Capillary supercritical fluid chromatography with flame ionisation detection was used for the separation of some underivatised triterpene acids such as betulinic, oleanolic, polpunonic and ursolic acids. Supercritical fluid chromatography showed advantages over capillary gas chromatography since derivatisation was not required and separation was obtained in less than 15 min with high efficiency and good resolving power.
