Objectives : This research was observed by examining the external and internal parts and the quantity of the surface components of the wild type and cultivar of Angelica dahurica in korea. Methods : The slice of the tested material mede by paraffin section technique was colored with Safranine Malachite Green contrast methods, and then observed and photographed by the microscope and examined the quantity of the surface components. Results : In the shape of the roots, the wild type had a very thin main root and 2 long roots, while the cultivar had a long root branched out from the short and thick main root making a square pyramid shape. Isoimperatorin was detected at Rt $17{sim}18$ minutes. The wild type contained 0.56% while the cultivar contained it of 0.355%, thus the component of the wild type was about 1.5 times of that of the cultivar. Conclusions : It was thought that there might be also some differences in their genetic characteristics, etc.
