Abstract: Two new saponins, Inflasaponin Ⅲ and Inflasaponin Ⅴ were obtained from 10% EtOHextracts of Glycyrrhiza inflata Bat.through HPLCisolation and purification.On the basis of chemical and spectroscopic evidences, their structures were identified as Liouiritic acid-3-O-β-D-6"-n-butyl-gluctironopyranosyl-(1→2).-β-D-6'-ethyl-glucuronopyranoside, Liquiritic acid-3-O-β-D-6"-n-butyl-glucuronopyranosyl-(1→2)-β-D-6'-n-butyl-glucuronopy-ranoside, The ¹³C NMRdata of metliyl-liquiritic ester were reassigned.
