A HPLC method with amperometric detection is established for the contact allergen alpha-peroxyachifolid (1) from yarrow (Achillea millefolium L., s. str.). The amounts of 1 are between 0.25 and 0.60% in blossoms, dried 2 h at room temperature, and between 0.01 and 0.05% in the leaves. In completely dried material and in some preparations from the market 1 could also be quantified.
