从长春花(Catharanthus roseus)一株悬浮细胞(CRW)中分离到Iboga型、Strychnos型和Aspido-sperma型生物碱,并通过同位素标记前体DL-tryp-tophan-[3-~(14)C](色氨酸)加入悬浮细胞培养基中,获得
Iboga type, Strychnos type and Aspido-sperma type alkaloids were isolated from a suspension cell (CRW) of Catharanthus roseus and were identified by isotope labeling of DL-tryp-tophan- [3-14 C ] (Tryptophan) into suspension cell culture medium
