Mch. Tavares et al., Separation of underivatised triterpene acids by capillary supercritical fluid chromatography, PHYTOCH AN, 12(2), 2001, pp. 134-137
Capillary supercritical fluid chromatography with flame ionisation detectio
n was used for the separation of some underivatised triterpene acids such a
s betulinic, oleanolic, polpunonic and ursolic acids. Supercritical fluid c
hromatography showed advantages over capillary gas chromatography since der
ivatisation was not required and separation was obtained in less than 15 mi
n with high efficiency and good resolving power. Copyright (C) 2001 John Wi
