By the use of absorption, partition and paper chromatography as well as counter‐current distribution 18 pure crystalline cardenolides (B, γ, C, δ, D, E, F, G, H, I, K, L N, 0, P, π, ς and Q) and a further crystalline KEDDE‐positive compound (A) were isolated after fermentation of the seeds of Nerium oleaizder L. The compounds H, I and e were identified with known genins; namely Digitoxigenin (H), Oleandrigenin (I) and Gitoxigenin (ς). Of the remaining 15 compounds, 14 were found to be glycosides composed of the 4 genins H, I, ς and 16‐Anhydro‐gitoxigenin with the following sugars: L ‐Oleandrose, D ‐Diginose, D ‐Samentose and D ‐Digidose. 10 of these glycosides have previously been isolated in pure form. They are: Digistroside (γ), Oleandrin (C), Cryptograndoside A (d), 16‐Anhydro‐desacetyl‐cryptograndoside A (D), Odoroside A (E), Desacetyl‐oleandrin (K), Desacetyl‐cryptograndoside A (L), Odoroside H (0), 16‐Anhydro‐strospeside (n) and Strospeside (Q). The other 4 are new compounds whose structures were elucidated and which were named as follows: Nerigoside (F), 16‐Anhydro‐desacetyl‐nerigoside (G), Desacetyl‐nerigoside (N) and Neritaloside (P).
