The seeds ofStrophanthus kombe Oliv. have yielded 12 cardiac glycosides. Of them, six were identified with known cardenolides: S 1 - periplocymarin; S 2 - cymarin; S 4 -periplocin; S 5 - k-strophanthin-β; S 7 - erysimoside; S 8 - k-strophanthoside. The structure of k-strophanthoside as strophanthidin 3β-[O-β-D-glucopyranosyl-(1→6)-O-β-D-glucopyranosyl-(1→4)-β-D-cymaropyranoside] has been confirmed. This is apparently the first time that the other six glycosides have been isolated… CONTINUE READING
