Abstract: A new atisine type diterpenoid named spiramilactone B (1) was islolated from the roots of Spiraeajaponica var.stellaris. Its structure was established by a spectroscopic analysis. In addi-tion, nine known compounds were also obtained, including a atisine-type diterpenoid, spiraminol(2) and eight diterpenoid alkaloids, spiramine A, B, C, D, F, H, P, Q.

Key words: Spiraea
