title: Structures of the two saponins isolated from commercially available root extract of Primula sp.
abstract: The two main saponins of commercially available extract of Primula sp. were isolated by HPLC. Their structures were elucidated by spectroscopic methods as already known primulasaponin (1) and the new 3-O-¿[alpha-rhamnopyranosyl-(1-->2)-beta- galactopyranosyl-(1-->3)-[beta-xylopyranosyl-(1-->4)-beta-glucopyranosyl - (1-->2)]-beta-glucuronopyranosyl]¿-protoprimulagenin A (2).
