New diterpene alkaloids from the roots of Spiraea japonica

J Nat Prod. 2001 Mar;64(3):379-80. doi: 10.1021/np0004911.

Abstract

Chemical investigation on an ethanol extract from the roots of Spiraea japonica var. acuta resulted in the isolation of three new diterpene alkaloids named spiramide (1) and spiratine A (2) and spiratine B (3). Structures of 1-3 were elucidated primarily on the basis of 1D and 2D NMR experiments.
