Structures of the two saponins isolated from commercially available root extract of Primula sp.
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).
