Weitere Phloroglucin- und alpha-Pyron-Derivate aus Helichrysum-Arten.
The investigation of three South African HELICHRYSUM species afforded a tremetone derivative, where the acetyl group is methylated, four phloroglucin derivatives, two of them being chromones, four alpha-pyrone derivatives and a dihydro chalcone also derived from phloroglucine. The structures were elucidated by sepectroscopic methods.
