A comparative anatomy has been carried out on the Scopolia rhizomes imported from China, North Korea and Europe to Japan. Although the original plants of Chinese and North Korean scopolia rhizomes have not been clarified, both materials resemble the rhizome of Scopolia parviflora NAKAI in anatomical features whereas they differ from the rhizome imported from Europe (Scopolia carniolica JACQ.) in the arrangement of vessels. As for alkaloids among various materials, no qualitative difference was detected by thin layer chromatography of the chloroform extracts (Fig. 6). The contents of scopolamine (sc) and atropine (at) and ratio of sc. to at. varied widely depending upon the plant or the part of rhizome even in the same species. The younger parts of rhizome showed significantly higher values than the older parts. However the average alkaloid contents of the imported rhizomes were generally higher than those of the Japanese rhizomes (TABLE I).
