Three alkaloids, neoharringtonine, homoneoharringtonine and 3'S-hydroxyneoharringtonine, were isolated from the leaves and stems of Cephalotaxus harringtonia var. drupacea. Their structures were established by spectroscopic methods, including two-dimensional NMR and CD spectra, and their antileukaemic activity was evaluated using P-388 leukaemia cells.
从 Cephalotaxus harringtonia var. 的叶子和茎中分离出三种生物碱,新三尖杉酯碱、高三尖杉酯碱和 3'S-羟基新三尖杉酯碱。核果。它们的结构是通过光谱方法建立的,包括二维核磁共振和 CD 光谱,并使用 P-388 白血病细胞评估它们的抗白血病活性。
