From the roots and rhizomes of Primula elatior the main saponin (PS 4) and four minor saponins were isolated.In the case of one (PS 3) of the minor saponins, the genuine aglycon of which was identified as protoprimulagenin A (1), the structure of the sugar chain consisting of D-glucose, D-glucuronic acid, D-galactose, and L-rhamnose has been established.The structure of the sugar chain of the main saponin has been revised.
