Weitere Phloroglucin- und α-Pyron-Derivate ausHelichrysum-Arten

Abstract

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 α-pyrone derivatives and a dihydro chalcone also derived from phloroglucine. The structures were elucidated by sepectroscopic methods.
