Die Glykoside der Blätter von Isoplexis isabelliana (WEBB) MASF.. 3. Mitteilung

Abstract: Isoplexis isabelliana (WEBB) MASF. ( h (unbekanntes 2-Desoxosid). Versuche, die diesen Monosiden entsprechenden genuilien Glucosido-Verbindungen zu isolieren, schlugen fehl.In der vorliegenden Arbeit wird die Auftrennung der genuinen Glykoside des Chloroform-Alkohol-(4 : 1)-Extraktes 3, beschrieben.

“…The mixture of glycosides yielded the diglycosides glucoevatromonoside, cheiroside A and 'digitalinum verum' together with other derivatives of digitoxigenin, uzarigenin and xysmalogenin directly bound to 6-deoxy-D-glucose, its 2-0-acetyl compound, D-canarose or D-digitoxose and terminating by a glucose unit. The C 21 -steroid glycosides digifolein, diginin, lanafolein, 141X.-digipronin and strospeside and the genins y-digiprogenin, purpnigenin, 3~, 14 ~-dihydroxypregn-5-en-20-one, 3~, 14 ~-dihydroxypregn-5-en-15,20-dione and its digitoxoside were also found as well as the spirostan sapogenins tigogenin and neotigogenin (Breton & Gonzalez 1960b;Rees et al 1961a;Pavanaram et al 1963f;Freitag et al 1967g).…”

“…Andernfalls werden bei der milden Verseifung der Peracetylverbindungen mit KHCO, nur die leicht spaltbaren Acetylgruppen in den Zuckerresten verseift, nicht aber diejenigen im Geninanteil, wodurch eine Regenerierung der genuinen Glykoside unmoglich wird. (vgl. hierzu [ 8 ] ) danken.…”
