In completion of our studies on Achillea exudate flavonoids, 11 alpine species of Achillea sect. Ptarmica were analyzed for their aglycone profiles. The study focuses on species commonly associated with A. moschata. The major flavonoid constituents found in exudates of most taxa were 6-hydroxyflavonol 3,6,4'-trimethyl ethers, except in A. ageratifolia and its subspecies, which are characterized by the accumulation of the 3,6,7-trimethoxy and 6-hydroxyflavones. Infraspecific variation was… CONTINUE READING
