Abstract: Anatomical structure and the content of barbloin in primary roots of Pulsatilla chinensis were studied bymeans 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 .

Key words: Pulsatilla chinensis
