Die Glykoside der Wurzeln von Kanahia laniflora (FORSSK.) R. BR. 2. Mitteilung: Struktur von Kalanosid-H und Kalanosid-K† Glykoside und Aglykone, 300. Mitteilung‡

The total acidic hydrolysis of kalanoside-H and kalanoside-K yielded 12-O-acetyl-17-isolineolon as well as three sugars: oleandrose, canarose and digitoxose. From partial hydrolysis and UV., IR. and NMR. spectral data, it could be concluded that kalanoside-H is probably a trisaccharide glycoside having the partial formula 1a or 1b, and similarly that kalanoside-K has probably the partial formula 2.
