Abstract: BY means of HPLC isolation ,seven triterpenoid saponins were isolated from theroots and rhizomes of Glycyrrhiza inflata Bat.Two of them were identified as glycyrrhetic acid-3-O-β-D-6″-methyl-glucuronopyranosyl-(1→2)-β-D-6′-n-butyl-glucuronopyranoside(Ⅱ )and glycyrrheticacid-3-O-β-D-6″-n-butyl-glucuronopyranosyl-( 1→2)-β-D-6′-butyl-glucuroi1opyranoside(Ⅰ)onthe basis of chemical and spectroscopic methods ,and named as inflasaponinⅠand inflasaponin Ⅳ,respectively。
