摘要: 通过HPLC测定了喜树(Camptotheca acuminata)不同器官及不同种源幼枝中喜树碱的含量。结果表明, 喜树碱含量在叶、种子和幼枝(幼叶和幼茎)中较高, 木质部中较少, 髓中最低。不同种源的幼枝中, 来自成都种源喜树的喜树碱含量最高。通过比较, 两年生喜树各器官中喜树碱含量普遍比一年生高, 幼枝中顶枝的喜树碱含量比侧枝高。

Abstract: Camptothecin (CPT) content in organs of Camptotheca acuminata and young shoots from different areas of China was determined by HPLC. CPT content in leaves, seeds and young shoots was higher than that in xylem, lowest in piths and highest in young shoots from Sichuan province. CPT content in young biennial shoots was higher than that in annual shoots and that in caulody was higher than that in subbranches.
