An investigation of 14 samples of Tansy (Tanacetum vulgare L.), naturally occurring in the North-Eastern part of the Netherlands, revealed the presence of an artemisia ketone, a chrysanthenol/chrysanthenyl acetate, a lyratol/lyratyl acetate and a β-thujone chemotype. The essential oils of the flower heads contained a higher percentage of the main constituent than the oil obtained from the leaves. Vulgarone A and B were detected in five samples; however, vulgarone A was only found in the leaf oils. Cis-longipinane-2, 7-dione, a component of Bulgarian Tansy, could be detected only in two samples.
