摘　　要：Chemical investigation on the ethanol extract from the whole plants of Delphinium chrysotrichum resulted in the isolation of two new diterpene alkaloids named delphatisine A （1） and delphatisine B （2）, respectively. The structures of the new compounds were deduced on the basis of their spectral data （IR, HREIMS, EIMS, 1 D, 2D-NMR）. This is the first report on the isolation of diterpenoid alkaloids from the D. chrysotrichum.Chemical investigation on the ethanol extract from the whole plants of Delphinium chrysotrichum resulted in the isolation of two new diterpene alkaloids named delphatisine A （1） and delphatisine B （2）, respectively.
