摘　　要：皂苷类物质是白头翁的重要药用成分,主要存在于根内。研究白头翁根的解剖结构与皂苷类物质的关系有重要意义。利用解剖学和组织化学定位方法对不同生长龄白头翁根的解剖结构和皂苷的储藏场所进行了研究.结果表明：栓内层和次生韧皮部中的分泌细胞团、分泌腔和分泌道是白头翁根的主要结构特征,是皂苷类物质的主要贮存场所;而分泌腔和分泌道的数量及分泌道的宽窄与生长年限相关,4-5年生达到最大值。推测白头翁的栽培年限应为4年。The barbloin substance which mainly exist in the roots is the important medicinal ingredient in the plant of the Pulsatilla chinensis. The study of their relationship between anatomical structure of Pulsatilla chinensis＇ root and barbloin substance is of great significance. A study on the anatomical structure and the barbloin＇s store place of Pulsatilla chinensis of different growth lengths by anatomy and barbloin histochemical localization shows that multicellular nodulos, secretory cavities and secretory ducts in phelloderm and secondary phloem ＂are the primary place of the barbloin substances and the major structural characteristics, wide or narrow of the secretory ducts is related to the growth length, 4 to 5 years old reaches maximum. The growth length of Pulsatilla chinensis is supposedly 4 years.
