Abstract

Phytochemical investigation on the ethanol extract from the stems of Spiraea formosana has resulted in the isolation of four new neolignans, named spiraformin-A, -B, -C and -D (1—4), together with thirty five known compounds. Their structures were established primarily on the basis of 1D and 2D NMR spectral and chemical transformation methods.
