摘　　要：利用解剖学和组织化学的方法,研究了野生和栽培白头翁(Pulsatilla chinensis)主根的解剖结构和皂苷组织化学定位。结果表明:野生白头翁根部韧皮纤维散在,而栽培白头翁的则多个聚集成环状或其它形状;栽培白头翁根的次生木质部导管管腔内富含侵填体;野生白头翁根中分泌腔和分泌道丰富;分泌腔与分泌道的数量及大小是决定白头翁皂苷物质含量高低的主要因子。因此,分泌腔与分泌道大小和数量的多寡可以作为判断所选育的白头翁品种是否优良的结构性指标。Anatomical structure and the content of barbloin in primary roots of Pulsatilla chinensis were studied by means of anatomy and histochemical localization. The differences between wild and cultivated P. chinensis were as follows： the phloem fiber in roots of wild P. chinensis was dispersed, while that in the cultivated roots gathered to circular or other shapes; a large amount of invade body was found in the vessel cavity of the cultivated; secretory ducts and secretory cavities were rich in the wild, the number and size of which are the main factors determining the barbloin content of P. chinensis.
