    Description / Table of Contents: Triterpenes XXVIII1). The Saponins of Spinach (Spinacia oleracea L.)Two saponins, spinasaponin A and B, have been isolated from the roots of spinach. The structures are elucidated by acid and enzymatic hydrolysis and by methylation, fission of the resulting methyl derivatives, and identification of the methyl sugars. Accordingly, spinasaponin A is 3O-[β-D-Glucopyranosyl(1 → 3)-β-D-glucuronopyranosyl]-3β-hydroxy-Δ12-oleanen-28-acid (1a), whereas B is the corresponding derivative 2a of hederagenin.
    Notes: Aus den Wurzeln des Spinats werden zwei Saponine, Spinasaponin A und B, isoliert, deren Struktur durch saure und enzymatische Hydrolyse sowie durch Methylierung, Spaltung der Methyl-Derivate und Identifizierung der methylierten Zucker ermittelt wird. Spinasaponin A ist demnach eine 3O-[β-D-Glucopyranosyl(1 → 3)-β-D-glucuronopyranosyl-(1)]-3β-hydroxy-Δ12-oleanen-28-säure (1a), während B das entsprechende Hederagenin-Derivat 2a ist.
