ALKANE CONSTITUENTS OF THE PYRETHRUM FLOWER HEAD TANACETUM CINERARIAEFOLIUM AND THEIR DISTRIBUTION

The major components of the alkane fraction of the pyrethrum flower head are shown to be a series of n-alkanes from C₂₃ to C₃₁. The presence of minor components of complex composition having an equivalent carbon range of C₃₃ to C₄₃ is recognised.
Analysis of the separated flower head reveals that the anther and stamen together with the associated pollen are rich in n-C₂₅ while the remaining parts have n-C₂₉ as the major component.
