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
通过吸收,分配和纸色谱法以及逆流分布,获得了18种纯结晶烯属内酯(B,γ,C,δ,D,E,F,G,H,I,K,LN,0,P,夹竹桃L的种子发酵后,分离出另一种结晶的KEDDE阳性化合物(A)。即
