title: Phytotoxic cis-cinnamoyl glucosides from Spiraea thunbergii.
abstract: Spiraea thunbergii Sieb. was found to contain 1-O-cis-cinnamoyl-beta-D-glucopyranose and 6-O-(4'-hydroxy-2'-methylene-butyroyl)-1-O-cis-cinnamoyl-beta-D-glucopyranose as major plant growth inhibitory constituents along with related compounds of lower phytotoxicity including 6-O-(trans-cinnamoyl)-1-O-(4"-hydroxy-3"-methyl-furan-2"-one)-beta-D-glucopyranose, 6-O-(4'-hydroxy-2'-methylene-butyroyl)-1-O-trans-cinnamoyl-beta-D-glucopyranose, and 1-O-trans-cinnamoyl-beta-D-glucopyranose. The former three compounds were cinnamoyl glucosides.
