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.
