Chuan Wu (Aconitum carmichaeli Debx.) is a famous chillese drug and is also an important original materials of thc famous Fuzi. The plant was much investigated by both chinese and japanese scientists. In this communication, we have investigated the plant which was introduced by a fine variety from Sichuan and cultivated at Dali prefecture of Yunnan. To bc very intcresting we found that this plant not only changes in quantity of alkaloidal constituents but changes in quality as well in making comparison with Chuan wu cultivated at Shanxi. We also isolated neolinc, songorine and a new compound fuziline from this plant except mesaconitine, hypaconitine, and aconitine reported before.
