Abstract

IN 1962, it was reported that the petals of Paeonia albiflora Pall. contain considerable quantities of “pyrethroids”1. The chemical evidence was based on ultraviolet absorption maxima and on the supposed isolation of chrysanthemum mono- and di-carboxylic acids. Evidence that the compounds isolated from the peony were not identical with the pyrethroids that occur in Chrysanthemum cinerariaefolium is the reported melting point (205–206°) for the diacid. Naturally occurring (+)-chrysanthemum dicarboxylic acid has a melting point of 164° (ref. 2).
