Primula elatior (L.) Hill - Primulaceae - oxlip, Hohe Schlüsselblume, (Gewöhnliche, Wald-) Schlüsselblume,
Perennial herb, up to 30cm high, native to Europe, Sibiria, West Asia; leaves erect, pubescent; inflorescence umbel-like on a long stalk; flowers pale yellow, not as fragrant as P.veris.
„It may be confused with the closely related Primula veris (cowslip), which has a similar general appearance, although P. veris has smaller, bell-shaped, bright yellow flowers (and red dots inside the flower), and a corolla tube without folds. The leaves of P. veris are more spade-shaped than P. elatior.“
Flowers and roots of P.elatior are medicinally used the same way (expectorant and secretolytic to treat bronchitis, cough, colds and catarrh of the nose and throat) as Primula veris.
„From the roots and rhizomes of Primula elatior the main saponin (PS4) and four minor saponins were isolated. In the case of one (PS3) 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.“

The flower scent of P.elatior consist mostly of limonene (94%) with small amounts of sabinene, α-pinene, myrcene, and benzaldehyde.
